Abstract
Objective
To explore the extent to which national policies guaranteeing breastfeeding breaks to working women may facilitate breastfeeding.
Methods
An analysis was conducted of the number of countries that guarantee breastfeeding breaks, the daily number of hours guaranteed, and the duration of guarantees. To obtain current, detailed information on national policies, original legislation as well as secondary sources on 182 of the 193 Member States of the United Nations were examined. Regression analyses were conducted to test the association between national policy and rates of exclusive breastfeeding while controlling for national income level, level of urbanization, female percentage of the labour force and female literacy rate.
Findings
Breastfeeding breaks with pay are guaranteed in 130 countries (71%) and unpaid breaks are guaranteed in seven (4%). No policy on breastfeeding breaks exists in 45 countries (25%). In multivariate models, the guarantee of paid breastfeeding breaks for at least 6 months was associated with an increase of 8.86 percentage points in the rate of exclusive breastfeeding (P < 0.05).
Conclusion
A greater percentage of women practise exclusive breastfeeding in countries where laws guarantee breastfeeding breaks at work. If these findings are confirmed in longitudinal studies, health outcomes could be improved by passing legislation on breastfeeding breaks in countries that do not yet ensure the right to breastfeed.
Résumé
Objectif
Découvrir dans quelle mesure les politiques nationales garantissant les «pauses allaitement» pour les femmes qui travaillent peuvent faciliter l'allaitement.
Méthodes
Une étude a été menée sur le nombre de pays qui mettent en place des «pauses allaitement», le nombre d'heures octroyées par jour et la durée de vie de ces dispositions. Pour obtenir des renseignements détaillés et à jour sur ces politiques nationales, des lois locales et des sources secondaires de 182 des 193 États membres des Nations Unies ont été examinées. Des analyses de régression ont été menées afin d'analyser le lien existant entre la politique nationale en vigueur et le pourcentage de femmes ayant opté pour un allaitement maternel exclusif, tout en contrôlant le niveau de revenu national, le niveau d'urbanisation, le pourcentage de femmes actives et le taux d'alphabétisation des femmes.
Résultats
Les «pauses allaitement» rémunérées ont été mises en place dans 130 pays (71%) et les pauses non rémunérées dans 7 d'entre eux (4%). L'absence de politiques sur les «pauses allaitement» est à noter dans 45 pays (25%). Dans les modèles multivariés, la mise en place de «pauses allaitement» rémunérées pendant au moins 6 mois a été associée à une augmentation de 8,86 points du pourcentage d'allaitement exclusif (P < 0,05).
Conclusion
Un pourcentage plus élevé de femmes pratiquent l'allaitement maternel exclusif dans les pays où les lois garantissent des «pauses allaitement» au travail. Si ces résultats sont confirmés dans des études longitudinales, les répercussions sur la santé pourraient être bénéfiques si des lois sur les «pauses allaitement» étaient adoptées dans les pays qui ne garantissent pas encore le droit à l'allaitement.
Resumen
Objetivo
Investigar en qué medida podrían facilitar la lactancia las estrategias nacionales que garantizan permisos de lactancia para mujeres trabajadoras.
Métodos
Se realizó un análisis del número de países que garantizan los permisos de lactancia, el número diario de horas garantizado y la duración de esos permisos. A fin de obtener información actual y detallada sobre las estrategias nacionales, se examinaron tanto la legislación original como fuentes secundarias de 182 de los 193 Estados Miembros de las Naciones Unidas. Se llevaron a cabo análisis de regresión para examinar la asociación entre la estrategia nacional y las tasas de lactancia exclusiva, al tiempo que se tuvo en cuenta el nivel de ingresos nacional, el nivel de urbanización, el porcentaje de mujeres de la población activa y la tasa de alfabetización femenina.
Resultados
Los permisos de lactancia remunerados están garantizados en 130 países (71%). Siete países (4%) garantizan permisos de lactancia no remunerados y en 45 países (25%) no existe ninguna estrategia sobre la lactancia. En modelos multivariados, los permisos de lactancia remunerados garantizados durante al menos seis meses estuvieron asociados con un aumento de 8,86 puntos porcentuales en la tasa de lactancia exclusiva (P< 0,05).
Conclusión
El porcentaje de mujeres que practica la lactancia exclusiva fue mayor en los países en los que las leyes garantizan los permisos de lactancia en el trabajo. Si estos resultados quedaran confirmados con estudios longitudinales, sería posible mejorar los resultados sanitarios mediante la aprobación de legislación sobre permisos de lactancia en aquellos países que aún no garantizan el derecho a la lactancia.
ملخص
الغرض
استعراض إلى أي حد قد تسهّل السياسات الوطنية التي تضمن راحات الرضاعة الطبيعية للسيدات العاملات من الرضاعة الطبيعية.
الطريقة
تم إجراء تحليل لعدد البلدان التي تضمن راحات الرضاعة الطبيعية، وعدد الساعات اليومية المضمونة، ومدة الضمانات. وللحصول على معلومات مفصلة وحديثة عن السياسات الوطنية، تم دراسة التشريعات الأصلية وكذلك المصادر الثانوية في 182 دولة من الدول الأعضاء في الأمم المتحدة البالغ عددها 193 دولة. وتم إجراء تحليلات الارتداد لفحص العلاقة بين السياسة الوطنية ومعدلات الاقتصار على الرضاعة الطبيعية مع السيطرة على مستوى الدخل الوطني ومستوى التوسع الحضري والنسبة المئوية للإناث في القوى العاملة ومعدل الإلمام بالقراءة والكتابة لدى الإناث.
النتائج
يتم ضمان راحات الرضاعة الطبيعية مدفوعة الأجر في 130 بلداً (71 %)، ويتم ضمان الراحات غير مدفوعة الأجر في سبعة بلدان (4 %). ولا توجد سياسة معنية براحات الرضاعة الطبيعية في 45 بلداً (25 %). وفي النماذج متعددة المتغيرات، ارتبط ضمان راحات الرضاعة الطبيعية مدفوعة الأجر لمدة 6 أشهر على الأقل بزيادة قدرها 8.86 في المائة نقطة في معدل الاقتصار على الرضاعة الطبيعية (الاحتمال < 0.05).
الاستنتاج
تمارس نسبة أكبر من النساء الاقتصار على الرضاعة الطبيعية في البلدان التي تضمن فيها القوانين راحات الرضاعة الطبيعية في العمل. وإذا تم تأكيد هذه النتائج في دراسات طولانية، فمن الممكن تحسين الحصائل الصحية من خلال سن تشريعات تختص براحات الرضاعة الطبيعية في البلدان التي لا تضمن حتى الآن حق الرضاعة الطبيعية.
摘要
目的
探索保证工作妇女哺乳时间的国家政策可以在何种程度上促进母乳喂养。
方法
对保证哺乳时间的国家的数量、每天保证的小时数、保证期限进行分析。为了获得国家政策当前的详细信息,对原始立法以及联合国193 个会员国中182 个国家的第二手资料进行检查。执行回归分析,以对照国家收入水平、城镇化水平、劳动力女性比例和女性识字率检测国家政策和纯母乳喂养率之间的关联。
结果
有130 个国家(71%)可保证有薪哺乳时间,有7 个国家可保证无薪哺乳时间(4%)。有45 个国家(25%)没有哺乳时间政策。在多变量模型中,至少6 个月有薪哺乳时间的保证与纯母乳喂养率增长8.86 个百分点(P <0.05)相关。
结论
在有法律保证提供工作妇女哺乳时间的国家中,妇女进行纯母乳喂养的比例更高。如果纵向研究证实这些发现,在还没有确保母乳喂养权利的国家中,可经由通过哺乳时间立法来改善卫生成果。
Резюме
Цель
Изучить, в какой степени национальная политика, гарантирующая для работающих женщин перерывы в работе для кормления ребенка, может способствовать грудному вскармливанию.
Методы
Для ряда стран, гарантирующих для женщин перерывы для грудного вскармливания детей, был проведен анализ, включающий сравнение ежедневного количества гарантированных часов перерыва и продолжительность предоставления таких гарантий. Для получения обновленной и подробной информации о национальных политиках были исследованы как непосредственно законодательства стран, так и вторичные источники информации о 182 из 193 государств-членов Организации Объединенных Наций. Для проверки связи между национальной политикой и распространенностью исключительно грудного вскармливания проводился регрессионный анализ с поправками на национальный уровень доходов, уровень урбанизации, процент женщин в составе рабочей силы и уровень грамотности среди женщин.
Результаты
Оплачиваемые перерывы для грудного вскармливания гарантированы в 130 странах (71%), а неоплачиваемые перерывы гарантированы в 7 странах (4%). В 45 странах (25%) отсутствуют политики в отношении перерывов для грудного вскармливания. В многовариантных моделях гарантия оплачиваемого перерыва для грудного вскармливания в течение как минимум 6 месяцев была связана с увеличением показателя исключительно грудного вскармливания на 8,86% (P < 0,05).
Вывод
Больший процент женщин практикует исключительно грудное вскармливание в странах, где законы гарантируют женщинам перерыв для грудного вскармливания. Если эти данные подтвердятся в продольных исследованиях, то могут быть получены положительные результаты в сфере общественного здравоохранения путем принятия законов о перерывах для грудного вскармливания в странах, которые еще не обеспечили своим женщинам право кормить детей грудью.
Introduction
Breastfeeding lowers the risk of diarrhoeal disease by four- to 14-fold1 and the risk of respiratory illness by fivefold.2 Although the absolute benefits are greater in settings of poverty, poor nutrition and poor hygiene, where baseline disease rates are higher, the relative risk of these illnesses is significantly reduced by breastfeeding in high-income settings as well.3–5 Breast milk also markedly improves nutritional status in infants. Since malnutrition contributes to half of all infant deaths,6 breastfeeding helps to reduce infant mortality. Studies around the world in affluent and poor nations alike have shown a 1.5- to five-fold decrease in mortality among breastfed infants. 7–10 Breastfeeding has also been associated with lower rates of chronic diseases such as diabetes 11,12 and inflammatory bowel disease13,14 and with improved neurocognitive development. 15–18
Breastfeeding is beneficial to the health of both women and infants. Women who breastfeed have longer intervals between births and, as a result, a lower risk of maternal morbidity and mortality, as well as lower rates of breast cancer rates before menopause and potentially lower risks of ovarian cancer, osteoporosis and coronary heart disease.3,19 As a result, the World Health Organization (WHO) recommends exclusive breastfeeding for at least 6 months.20 Nonetheless, the rates of breastfeeding vary substantially around the world; the rate of exclusive breastfeeding among infants under 6 months of age ranges from 1% to 89%.21 One of the most common reasons that women stop breastfeeding is that they need to return to work.22–25 According to World Bank figures on the female share of the labour force, between 1960 and 2009 this share increased from 32% to 46% in the United States of America, from 25% to 47% in Canada, and from 21% to 41% in Latin America and the Caribbean. In sub-Saharan Africa, East Asia and the Pacific, as well as in Europe and Central Asia, women already made up at least 40% of the labour force in 1960 and this proportion remained the same or increased over subsequent decades. In the Middle East and North Africa females comprised a smaller share of the labour force, but this share increased from 21% to 25% between 1960 and 2009.26,27
Working does not necessarily have to lead to lower rates of breastfeeding.28 The quantity and nutritional quality of breast milk are not undermined by maternal work or activity, including vigorous exercise, and there is no indication that working women are less interested in breastfeeding than non-working women.28,29 Rather, it is the difficulty of continuing to breastfeed under the conditions experienced when they return to work that women most often cite as the reasons for supplementary feeding or for weaning infants.22 A woman’s ability to breastfeed is markedly reduced when she returns to work if breastfeeding breaks are not available, if quality infant care near her workplace is inaccessible or unaffordable, and if no facilities are available for pumping or storing milk.30
Given that circumstances play a major role in whether women breastfeed after returning to work, it makes sense to ask whether providing breastfeeding breaks from work might not increase the number of women who breastfeed for the recommended 6 months. Legislation guaranteeing breastfeeding breaks could substantially improve working mothers’ ability to continue to breastfeed. However, it might not make a substantial difference if the legislation covers a small fraction of the labour force, if breaks are too short for women to be able to pump milk or breastfeed, if infants are far from workplaces and locations for storing pumped milk are not available, or if legislation is not enforced.
This study analyses how many countries guarantee mothers breastfeeding breaks, how long the daily breaks are, and how often the breaks are guaranteed for enough months so that women can breastfeed for the minimum 6 months recommended by WHO for breastfeeding. We then conduct the first analysis of how labour policies affect breastfeeding rates around the world. Understanding the relationships between national policy and breastfeeding rates is critically important because of the substantial health benefits of breastfeeding to infant and mother, in addition to the facts that the majority of pregnant women are now employed and that a sizable proportion of women prefer to breastfeed.31,32
Methods
In this study, we examined the number of countries that guarantee mothers breastfeeding breaks, the time allowed daily for breaks and the months of breaks granted. We conducted multivariate regression analyses to test the association between national policy on breastfeeding breaks and national rates of exclusive breastfeeding among women with children less than 6 months of age. We controlled for other national-level factors that could also influence the likelihood of a woman in a given country initiating and sustaining breastfeeding for a minimum of 6 months, as recommended by WHO.
Data sources
To obtain current, detailed information on national policies on breastfeeding breaks in the workplace, we collected and analysed information on breastfeeding policy in all Member States of the United Nations (UN). Our primary data source was original national labour legislation. Our research team reviewed all national labour legislation collected by the International Labour Organization (ILO) and available in their NATLEX database in original languages and in translations. While this comprehensive review of primary source legislation provided us with the most reliable information available on legal rights to breastfeeding breaks, the legislation has some limitations. The ILO repository relies on countries to provide updated legislation. Additionally, we did not capture any subnational variation in breastfeeding break policies or policies that were regulated at an industry level or for subsets of the labour force through collective bargaining. To supplement the data available through the ILO and ensure that we were using the most up-to-date information available, we reviewed legislation on line through country web sites, the World Bank’s “Doing Business” law library, and the Lexadin World Law Guide legislation database, as well as in hard copy through Harvard University, McGill University and the ILO headquarters library.33,34 Finally, to search for any additional information we also investigated secondary sources, such as reports on national policies, information compiled by global organizations, including the World Alliance for Breastfeeding Action, and the maternity protection component of the International Labour Organization’s Database of Conditions of Work and Employment Laws. These secondary sources were selected after a comprehensive computerized search of the academic and grey literature for comparative databases.35,36 Based on all of these sources, we developed a database with information on breastfeeding break policies for 182 of the 193 countries that were Member States of the United Nations at the time the database was last updated, in March 2012.
Nations vary in how they structure their laws on breaks for breastfeeding at the workplace. We had therefore gathered information on whether countries guarantee women the ability to take breastfeeding breaks at work, whether these breaks are paid, how much time is allowed daily for breaks, and for how many months after giving birth women are entitled to take the breaks. National policies also vary in terms of how the breaks can be scheduled. For example, some policies indicate the total time allotted for breaks without restriction on how the breaks are taken, whereas others specify whether each break has to be taken at once or can be split into multiple, shorter breaks. In some countries, legislation specifies the number of minutes of break allowed for a certain number of hours worked (e.g. 30 minutes over a four-hour period). In others, legislation stipulates that breaks can be accumulated and taken at the start or the end of the day, which shortens the number of hours per day that a woman works.
Analyses conducted
We conducted descriptive analyses of our data on breastfeeding breaks in the workplace to provide a global picture of working women’s ability to breastfeed their infants. Most commonly, the law specifies for how long women can take breastfeeding breaks in terms of the age of the child, but sometimes it does so in terms of the time transpired after a woman returns to work, in which case we added this to the total maternal leave available to new mothers since this is guaranteed time off. In this article, when breastfeeding breaks vary based on the employee’s tenure, hours worked or the number of young children, we report the minimum granted.
We used multivariate regression to test for an association between the presence of national legislation guaranteeing breastfeeding breaks at the workplace and breastfeeding rates. Ordinary least squares regression analyses were conducted. We conducted a stepwise regression analysis in which we first examined the effect of breastfeeding break policies, controlling only for national resources and level of urbanization (measures found in other research studies to be associated with breastfeeding rates).37,38 This model is referred to as the more “parsimonious” one. The sample for this model was the 116 countries with data on all three independent variables and the outcome variable – the rate of exclusive breastfeeding in infants aged less than 6 months. Female literacy rate, a proxy for degree of access to information, was then added. This model is referred to as the “full” model. The sample for the “full” model was the 108 countries for which data on all four independent variables and the outcome variable were available. All analyses included controls for the year of breastfeeding rate data available, since data for every country were not available for the same point in time and substantial efforts have been made internationally to promote exclusive breastfeeding rates as part of the Millennium Development Goals. Policies allowing women to take breaks from work to breastfeed affect employed women directly; they may also affect women outside the labour force indirectly through changing norms. To the extent that the laws have a direct effect, one would expect a greater impact where a greater number of women are in the paid labour force. To test this, we examined whether the policies on breastfeeding breaks in the workplace are associated with higher exclusive breastfeeding rates in countries with a higher female share of the labour force than in countries where females represent a smaller share. This was done by analysing the extent to which the breastfeeding outcomes are explained by the interaction between the guarantee of breastfeeding breaks and the national female share of the labour force. Again, first we estimated a “parsimonious” model in which we used national resources and level of urbanization as controls. For this model the sample size was the 115 countries with data on all included variables. We then estimated a “full” model that also included the female literacy rate as a control. For this model the sample size was 108 countries.
Variables
Outcome examined
The outcome variable in this study was the percentage of children aged less than 6 months who were exclusively breastfed in each country. The data were obtained from WHO’s Global Data Bank on Infant and Young Child Feeding,39 which contains internationally comparable data derived primarily from Demographic and Health Surveys, Multiple Cluster Indicator Surveys and Ministries of Health. Because of the nature of some of these sources, data on breastfeeding rates were more frequently available for lower-income countries. These rates were provided for 129 nations for at least one year between 2000 and 2011. When multiple years of data on breastfeeding rates were available, we used the most recent rate.
Key independent variables
Paid breastfeeding breaks
For every country for which we had labour policy information, we constructed a binary indicator variable and set it to 1 if national legislation required employers to offer paid breastfeeding breaks until the child was at least 6 months old, and to 0 in the absence of such legislation. For every nation included in our analysis, we verified that the legislation had been in place for at least one year before the year for which we obtained data on exclusive breastfeeding rates.
Per capita gross domestic product
From the World Bank’s World Development Indicators Online we obtained the gross domestic product (GDP) of each country, measured in purchasing-power-parity-adjusted constant 2005 international dollars, and used it as an indicator of national economic resource level.40 For analysis, we used GDP from the year for which exclusive breastfeeding rates were available. A log transformation of per capita GDP was used instead of a linear term to allow for the common finding that changes in income at the lower end of the income spectrum have a larger impact on breastfeeding rates than changes in wealth at the higher end of the income spectrum.
Female share of the labour force
The female share of the labour force is the percentage of females among members of the labour force. A rate of 50% would indicate that females and males make up an equal share of the labour force. We preferred this measure to the female labour force participation rate – i.e. the percentage of females active in the labour force – because it obviates the need to adjust for differences in cross-country employment rates. Our data were taken from the World Bank’s World Development Indicators Online.40 For analysis, we used female share of the labour force from the most recent year for which exclusive breastfeeding rates were available.
Female literacy rate
The female literacy rate was defined as the percentage of literate females among all females aged 15 years or older. We obtained the data from the World Bank’s World Development Indicators Online.40 We used the female literacy rate as a proxy for access to information (since information is disseminated in writing as well as orally). The influence of literacy on breastfeeding depends on the nature of the information made available to women. If substantial public health information on breastfeeding is provided in written form, literate women will have greater access to information on the benefits of breastfeeding. If advertising for formula is conducted in written form, then higher literacy rates may be associated with greater exposure to marketing and lower rates of breastfeeding. Countries’ female literacy rates are not available for every year. For analysis, we used the female literacy rate available for the most recent year for which data on exclusive breastfeeding rates for each country were available, or for the preceding year. For higher-income countries for which data were unavailable, we used a female literacy rate of 99%, consistent with the female literacy rate assumed by the United Nations Development Programme for such countries in constructing the Human Development Index.41
Urban percentage of the population
We included the percentage of the population living in an urban area as a control in the models because other researchers have found the level of urbanization to be negatively associated with breastfeeding rates.42,43 We extracted data from the World Bank’s World Development Indicators Online.40 For analysis, we used the urbanization rate for the year for which exclusive breastfeeding rates were available. Table 1 summarizes the variables included in the analyses.

Results
Of the 182 nations that had data for 2012 on the existence of a national policy for breastfeeding breaks in the workplace, 45 countries (25%) have no policy in place. A policy guaranteeing paid breastfeeding breaks is in place in 130 countries (71%) and seven countries (4%) have policies guaranteeing unpaid breaks. There is significant variation in the length of time for which working mothers have access to breastfeeding breaks (Table 2 and Fig. 1). Most nations’ policies specify how long employers must guarantee breastfeeding breaks in terms of the age of the child, rather than according to how long the employee has been back at work. Only three countries (Bhutan, San Marino and Swaziland) provide for breastfeeding breaks for less than 6 months after an infant’s birth. Working mothers are guaranteed a break most commonly until the infant is one year old. This is true of 41 countries. In 32 countries, the legislation does not specify the child’s age.

a Several countries in this group grant breaks for as long as the mother chooses to breastfeed.
The time allowed daily for breastfeeding breaks was specified in the policies of 111 of the 137 countries that had a policy. Most countries’ policies provide for a daily total of one hour during work for breastfeeding breaks. In 30 countries, breastfeeding breaks can be accumulated to shorten the work day. In 22 countries, the legislation specifies over how many hours the break can be spread; for example, if 30 minutes are allotted in total, the legislation might specify that the employee can take a single 30-minute break or two 15-minute breaks as long as the time is taken within a 3- or 4-hour window.
In multivariate models, national policies guaranteeing paid breastfeeding breaks at least until the child turns 6 months old were associated with significantly higher rates of exclusive breastfeeding. This was observed even when controlling for countries’ GDP per capita, percentage of the population living in an urban area, female literacy rate and year of exclusive breastfeeding data. The guarantee of paid breastfeeding breaks until the infant was at least 6 months of age was associated with an increase of 8.86 percentage points in the rate of exclusive breastfeeding of infants under 6 months of age (P < 0.05) in the full model (Model 2 in Table 3).

b The constant, or intercept, represents the breastfeeding rate predicted by the model before taking into account the influence of any independent variables.
As expected, our findings show that national policies guaranteeing breastfeeding breaks in the workplace are associated with a higher increase in exclusive breastfeeding in countries where the share of females in the labour force is higher (Table 4).44,45 The coefficient for the interaction of our policy indicator with the female share of the labour force is positive and statistically significant at the P < 0.05 level in the more parsimonious model as well as in the full model. Controlling for access to information did not affect the size or significance of the estimated coefficient. Based on the full model estimates, at the average female share of the labour force for the countries in the sample on which this model was run, which was 41%, a national policy guaranteeing breastfeeding breaks was associated with an increase of 7.7 percentage points in the rate of exclusive breastfeeding of infants less than 6 months of age. Fig. 2 shows the predicted rates of exclusive breastfeeding during the first 6 months of life for countries with and without a national policy guaranteeing breastfeeding breaks, by income group, with predictions based on the average value of each independent variable in the model.

Discussion
Although most countries guarantee breastfeeding breaks to working women, at least 45 of them had still failed to do so as of 2012. We found that the existence of a national policy guaranteeing breastfeeding breaks until an infant is at least 6 months old was associated with significantly higher rates of exclusive breastfeeding. This was true even after controlling for national GDP, female literacy rate and percentage of the population living in urban areas.
Because this study is cross-sectional, it can demonstrate association but not causation. The true effect size could differ from the estimated one if pre-existing breastfeeding rates influence the likelihood of countries passing legislation guaranteeing breastfeeding breaks. Longitudinal studies are needed to address this question. Nonetheless, the presence of clear mechanisms by which guaranteed breastfeeding breaks would contribute to the higher rates of exclusive breastfeeding suggest that the relationship is causal. If these results continue to be borne out, countries that do not yet have legislation that guarantees breaks for breastfeeding in the workplace may benefit greatly by passing such legislation. Any workplace that can provide a break for working adults to have a meal should be able to provide a break for working mothers to breastfeed. Our previous research has also demonstrated that countries can be economically competitive while providing these breaks.46 Yet without breastfeeding breaks, women who return to work less than 6 months after giving birth may not be able to breastfeed for as long as recommended to protect their infants’ health and their own. Policies that guarantee working women breastfeeding breaks for at least 6 months after giving birth increase the probability of exclusive breastfeeding for the recommended period.
Policies that provide for breastfeeding breaks at the workplace are in line with international agreements that protect the rights of children and women. The Convention on the Rights of the Child has been ratified by 190 countries. Article 24 of the Convention stipulates that “States Parties recognize the right of the child to the enjoyment of the highest attainable standard of health” and that “States Parties shall pursue full implementation of this right and, in particular, shall take appropriate measures: To diminish infant and child mortality.” The Convention goes on to refer specifically to the importance of breastfeeding. International conventions focusing on women also call for legislation seeking to ensure equity at work for mothers. The Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) requires that “States Parties shall take all appropriate measures to eliminate discrimination against women in the field of employment in order to ensure, on a basis of equality of men and women, the same rights.” CEDAW goes on to specifically call on all signatory countries “to prevent discrimination against women on the grounds of marriage or maternity and to ensure their effective right to work.”
The longer breastfeeding lasts, the greater its nutritional benefits and the greater the protection it confers against diarrhoeal disease. Moreover, a dose–response effect has been observed between breastfeeding duration and neurocognitive outcomes in children.11,12 Future research should examine the impact of policies guaranteeing breaks from work for breastfeeding children beyond the first 6 months of life and subsequent health outcomes for women and infants.
Little is known about the impact of legislation on breastfeeding breaks for women in the informal economy. Women who work independently, such as those who sell goods in marketplaces, may be able to bring their infants to work with them to feed. However, many women in the informal economy work for an employer. Some countries are starting to cover jobs previously considered part of the informal economy with labour legislation, to the extent possible. Extending policies on breastfeeding breaks to the informal sector should be readily feasible, since small employers can provide these breaks. Moreover, even in cases in which legislation does not apply to workers in the informal economy, it can help set norms and guidelines for all employers. Because many of the world's poorest women work in the informal economy, future studies should examine the extent to which these women are covered by breastfeeding policies in different countries.
