Abstract

Background

Adolescence is considered a critical period marked by an increase in energy intake to meet the body's physiological needs especially during puberty. This study reviews existing literature and critically analyses factors associated with eating habits and energy intake of adolescent girls.

Methods

A comprehensive search was conducted to identify at least 200 peer reviewed articles which dealt with the factors affecting energy intake (EI) and eating habits of adolescent girls. Studies were identified using a reference period between 1994 and 2016, based primarily on the PubMed/ CINL/ Science Direct/Google Scholar databases using keywords adolescent/ teenagers, factors/determinants and energy intake.

Results

No studies investigated all factors affecting energy intake among adolescents. Some studies found mixed association among the determinants of EI in adolescent girls. However, a number of reviews confirm that many factors namely physical activity level, socio-economic status, diet, individual and social factors do contribute to either a higher or a lower EI of adolescents.

Conclusion

There is a dire need to consider factors associated with EI when designing nutritional intervention programs to prevent health problems in adulthood. The goal is not to change behavior of all but to increase the percentage of people adopting healthier lifestyle.

Keywords: Adolescent girls, energy intake, physical activity level, socio-economic status, nutrition education

Background

Adolescence represents one of the critical transitions in the life span and is characterized by rapid physical growth and changes in body composition, physiology, and endocrine with profound biological, emotional, social, and cognitive changes1. During adolescence nutritional and energy needs are increased due to the increased growth rate and changes in body composition associated with puberty2. One point to be noted is that when energy intake (EI) exceeds energy expenditure, a state of positive energy balance occurs, resulting in weight gain3. Conversely, when energy expenditure exceeds EI, a state of negative energy balance ensues, and the consequence is weight loss4. Therefore, considering how nutritional related health problems have risen drastically due to failure to consume a balanced diet, it seems critical to understand the food preferences and their relationships to BMI in adolescents especially in girls. This review provides an insight into the different factors affecting energy intake of adolescent girls.

Methods

Several inclusion criteria were used to warrant that all pertinent studies were reviewed. Studies were included if they met the following: (a) subjects were teenagers; (b) published between 1994 and 2016; (c) measured overall energy intake as a dependent variable; (d) evaluated predictors, factors, and determinants of energy intake; (e) research reported in English. Published and unpublished studies were counted in this review. A systematic review of the literature was undertaken using a reference period between 1994 and 2016, based primarily on the PubMed/CINAHL/Science Direct/Google Scholar databases using the key words adolescent/youth/teenage, factors/determinants/predictors/correlates, and energy intake, eating habits. Computerized searches were directed on all the authors of the 220 studies that met the criteria. The titles and abstracts of the studies were screened for potential correlates of energy intake. From the initial search for peer-reviewed articles based on title and abstract, 138 full papers were read to assess if they should be considered further. Twenty-two studies were excluded because energy intake as well as eating habits were not a dependent variable. A total of 116 articles were considered appropriate for this review (Figure 1)

Results and discussion

Factors affecting energy intake & eating habits of adolescent girls

It is well documented that EI is positively correlated with eating habits5. For instance, Llaurado et al.6 found that as the number of eating occasions increased in adolescents, so did the overall EI. However, it is worth pointing out that there are a number of important factors that do contribute to either a higher or a lower EI (Figure 2).

Factors affecting energy intake

Personal factors

Hunger, appetite and satiety

Hunger is the physiological drive to find and eat food while appetite is the psychological desire to eat7. Satiety can be described as the state after a meal during which hunger is dampened and the urge to consume food is inhibited8. Weigle et al.9 reported that an isocaloric high-protein diet markedly increased satiety while slow eating has been shown to decrease hunger and promote greater satiety10. Many studies have demonstrated that slow eating helps control EI since it enhances satiety11. Consequently, decreased hunger and increased satiety will eventually discourage more food consumption, hence lower EI. However, the mechanisms responsible for regulation of appetite and food intake still warrants further investigation12.

Health status and body image

Nowadays it is the desire of most girls to be thin keeping in mind the ideal female body image. This attitude is driven, to a large extent by movie and television celebrities, fashion models and beauty pageant contestants whereby society considers thin to be healthy13. BMI is positively associated with concern about weight and shape and frequency of dieting and the latter was more prevalent among obese pre-adolescent and adolescent girls14.

Similarly, Japanese females with low BMI had high body dissatisfaction15. Moreover, Howe et al.16 reported a significant negative association between frequency of dieting and EI among high school students. However, Sharma et al.17 argued that body dissatisfaction was significantly associated with total energy intake with an increased intake of all macronutrients. Body image distortion and overall body dissatisfaction among adolescents may eventually lead to disordered eating behaviours such as anorexia nervosa or bulimia18. Raymond et al.19 observed that females who had binge eating disorders consumed significantly more kilocalories and more macronutrients while anorectic restrictors consumed significantly more energy to gain weight than did the anorectic bulimics (a mean of 3055 kcals per day vs. a mean of 2788 kcal per day)20. Contrarily, according to Higgins et al.21 patients with anorexia nervosa had a mean daily energy intake of 1272 kcal which was significantly lower than the mean EI for normal individuals.

Educational level and nutrition knowledge

Despite the fact that many young adults have inadequate knowledge about good nutrition, including information on recommended servings of specific food groups, only one in five (21.6%) university students felt a lack of nutritional knowledge (NK) was an actual barrier to healthy eating22. Most adolescents are fully aware of the type of food that they should consume. To support this, some studies have shown that some adolescents, despite having a significant amount of knowledge regarding healthy foods, find it difficult to follow healthy eating guidelines and frequently consume foods that they perceive as unhealthy23,24. On the other hand, girls had higher knowledge scores than boys25, particularly because girls and older adolescents were more likely to read nutritional food labels26,27. Although education was not associated with the risk of being thin, Alam et al. 3 reported that Bangladeshi girls with lower education were more likely to be stunted than girls with higher education. Despite the fact that many adolescent girls are not aware about their nutritional requirements28, knowledge of girls about the need for extra nutrients in adolescence did not have an effect on the prevalence of stunting29. However private school girls had significantly better knowledge than governmental school girls as regards to healthy food, low fat cheese, best food to eat during dieting28. As a matter of fact, O'Brien and Davies30, Shabaan et al.31 and Wolfgang et al.32 reported that there was no significant relationship between nutrition knowledge and BMI, nutrition behaviours or food preferences, suggesting that there may be reasons other than poor nutrition knowledge that account for the higher EI and BMI of respondents.

Environmental factors

Physical activity level and sedentary lifestyle

Physical activity (PA) plays a significant role in non-communicable diseases prevention and accounts for about 20–40% of total energy expenditure33. The working body requires energy and nutrients in order to fuel activity and function. PA, on the other hand, manipulates energy expenditure and regulates the use of fuels34. PA is closely interrelated with EI35 and has been shown to decline during adolescence especially among the American, Canadian and Finnish youth36. Increasing westernisation, urbanisation and mechanisation occurring in most countries around the world are associated with changes in the diet towards one of high fat, high energy-dense foods and a sedentary lifestyle37. Prolonged strenuous PA performed on a regular basis causes an increase in overall energy turnover, and leads either to loss of body weight, or to an increased food intake34. To support this statement, Zalilah et al.38, Fulton et al.35 and Goyal et al.39 reported that physical activity was inversely related to increases in BMI, overweight, obesity and adiposity whereby overweight children had reduced physical fitness due to increased physical inactivity. As energy output is increased through exercise, an individual must increase energy intake to match expenditure in order to maintain body mass. In highly physically trained persons, daily energy expenditure due to vigorous exercise is generally matched by a high-energy intake40. Obese adolescents engaged in sports less often than normal-weight and overweight participants, but underweight adolescents reported the least amount of time devoted to sports41. Interestingly Fokeena and Jeewon42 found that high PA was more common among the high SES adolescents as compared to the low SES. This can be due to the unsafe environments of the low SES neighborhoods and less access to recreational resources compared to high SES areas43. A decrease in spontaneous daily energy consumption and a reduction in energy balance were observed in obese adolescents with high intensity exercise whereas low intensity exercise had no effect on energy intake44.

Several studies have investigated the association between eating habits and (Physical activity levels)AL. Ottavaere et al.45 found that male and female adolescents with the highest physical activity levels, consumed more fruit and milk products and less cheese compared to the least active adolescents and that the energy intake was higher among those who participated more frequently in sport activities. Nowadays with advances in technology young teens spend more time in sedentary activities such as watching television, reading, eating, chatting with friends or playing video games than indulging in physical activities46. Fear of violence, secondary to drug dealing, and fear of kidnapping provide parents with no other alternatives than to keep children in the house and avoid outside sports and activities47. However physical activity and sedentary behavior are not always associated with children's overweight and/or obesity48 and one plausible explanation is that PA may not be a risk factor of obesity during adolescence49.

Socioeconomic status (SES)

Socioeconomic status (SES) is postulated to be a major predictor of dietary intake and lifestyle which are the major contributors to weight problems42. In a study among Lebanese adolescents, energy and nutrient intake analysis showed that adolescents in the high-SES group consumed significantly higher amounts of calories, protein, fat and significantly lower amounts of carbohydrates50. The relationship between SES and energy intake is complex. In developing countries, results are otherwise. The prevalence of stunting in urban Cameroon (Africa) was two times higher among the urban adolescents with low SES (12%) compared to those from high SES (5%)51. Urban adolescents with high SES and girls reported a more frequent consumption of in-between meals and most food groups compared to the rural adolescents. Lower education and lower socio-economically family background is associated with less healthy dietary patterns52. Children and young people from a lower socioeconomic background and those whose mothers had a lower level of education consume more sweets and high-fat bakery products as well as sugary and salted snacks, but lower vegetables intake53.

Contrarily Goyal et al.54 reported that the prevalence of overweight among children was higher in middle SES as compared to higher SES group while prevalence of obesity was higher in high SES group as compared to middle SES group. Additionally, Manios et al.55 reported that middle/ high SES children had higher energy intake compared to their low SES counterparts. This can be because high class people have better access to energy-dense and expensive foods such as meat than the poor54. Moreover Darmon et al.56 reported that adolescents with high SES had significantly higher percentage of energy intake from fat while the low SES had higher percentage of energy intake from carbohydrate. In contrast, Fokeena and Jeewon42 reported that among Mauritian adolescents, consumption of vegetables, low fat protein sources, and sweetened and fatty foods were higher in the low SES group while the high SES group consumed more fruits, wholegrain cereals, refined cereals, milk and dairy products whether low fat or full-cream, and high fat protein sources along with fast foods. While high income people can afford healthy food products, adolescents with low SES do not always eat properly because of poverty57. It has also been reported that female adolescents from larger families and males from families with higher incomes were less likely to be overweight and consumed less calories than their low SES peers58.

Availability and accessibility

During adolescence, teens spend less time with family and more time with friends. As teens become more independent, eating away from home increases59. The mushrooming of shopping malls, convenience stores, vending machines, delivery options, restaurants and fast food outlets encourage adolescents to practice unhealthy eating habits60. The average teen eats at a fast food restaurant at least twice a week. Fast food visits account for 31% of all food eaten away from home, and make up 83% of adolescent visits to restaurants59. This has eventually resulted an obesogenic environment whereby traditional foods face greater competition than before and high energy dense foods are made easily available for teenagers61. These food items, super-sized fast food meals, soft drinks, bags of chips, king- sized candy bars and oversized pizzas have contributed to excessive caloric sugar, high in glycemic load and fat intake among adolescents resulting in excess daily energy requirements62. Female adolescents who reported eating at a fast food restaurant ≥3 times in the past week had energy intake 37% more than those who did not eat at a fast food outlet63. Moreover mean energy intake from fast food meal among adolescents was extremely large (1652 kcal), accounting for 61.6% of estimated daily energy requirements64.

Social factor

Media

The mass media, mainly the television have become a powerful force throughout the world and strongly influence the behaviours of people65. Australian children are exposed to more television food advertising than probably children of every other nationality66. These long hours of television viewing are positively associated with overweight and obesity among girls65,67. These contribute to excess energy intake both by decreasing the amount of physical activity hence reducing energy expenditure and from increased unhealthy snacking during television viewing or as a result of exposure to food advertising68. High television/video use among boys and girls is associated with more unhealthful dietary behaviours (eg increased consumption of soft drinks, fried foods, and snacks). In contrast, time spent reading/doing homework was associated with more healthful dietary behaviours (such as increased consumption of fruits and vegetables) 69. Moreover, fast food restaurants and energy-dense foods and drinks are among the most advertised products on television63 and children are often the targeted market. The fat, sugar and energy content of foods advertised to children are very high compared to their daily needs70. Chou68 found a strong positive correlation between exposure to fast food restaurant advertising and the probability that children and adolescents are overweight especially among girls. However, such is not always true. According to Amos et al.65, media influences did not significantly correlate with students' eating habits. External factors such as values pertaining to food, socioeconomic status, family, and availability of food that have an impact on eating habits might have been the real predictors71. Interestingly female teens who are more concerned of their weight and figure, indulge in slimming diets and are more willing to choose low-fat foods such as fruits and vegetables72. Advertising healthy and nutritious foods to children encourage positive attitudes and beliefs towards the food and may increase children's willingness to choose healthy food as a snack73.

Influence of parents and friends

Studies have shown that parents and peers do have a strong influence on youths' eating habits especially on weight control behaviours of female adolescents74. Parental body weight is often described as a predictor of obesity in children, both in their childhood and adulthood, either to the genetic characteristics and/or attitudes and behaviours of parents with their children75. Brown and Odgen76 reported significant correlations between parent and child for reported snack intake, eating motivations and body dissatisfaction and therefore indicates an important role for modelling. Salvy et al.74 observed that female adolescents consumed more healthy foods and fewer unhealthy snacks when they were with their friends than when with their mothers which lead to the fact that parents may act as an inhibitory influence on healthy eating. In contrast, there has been opposing views on same whereby adolescents, out of home, consume healthy foods with family but more ‘junk type of food’ with peers77. Additionally, it has been reported that parents with longer working hours might have less time and energy to spend on preparation of healthy meals or exercise with their children78. However, Wang et al.79 concluded that there was a weak relationship between parental and child dietary patterns in the target urban low-income African-American population group in the United States while Scaglioni et al.80 found no relationship between parents' and child eating habits. Adolescents often compare themselves to their friends and may alter their choices to conform to the behaviour of their peers81. Amos et al.65 concluded that there was a significant positive relationship between peer influence and eating habits suggesting that the higher the peer pressure, the more unhealthy the students' dietary intake. All evidence suggests that the presence of peers and friends increases children and adolescents' energy intake74.

Culture (Veg vs Non-Veg diet)

Culture and religion is one of a broad range of factors that has an effect on the eating habits of adolescents82. Different ethnic groups demonstrate marked differences in the character and amounts of foods eaten47. People in the United States and other developed countries are becoming more affluent and able to afford more food especially processed and ready-to-eat foods, which tend to have a higher energy density while the median Indian household consumes far fewer calories than the recommended caloric intake83. Cultural food preferences vary most dramatically across India particularly vegetarianism because of the attitude towards animal products84.

Adolescents adopt vegetarian eating plans for a variety of reasons, including cultural or religious beliefs, moral or environmental concerns, health beliefs, as a means to restrict calories and/or fat intake and as a means of exerting independence by adopting eating behaviors that differ from those of the teen's family59. Restricted vegetarians are more likely to be females from a higher SES group and have healthier eating attitudes than the semi-vegetarian85. Vegetarian adolescents have been found to be shorter and leaner than omnivores during childhood and experience a delay in puberty and menarche at a later age than among non-vegetarians86. After puberty, vegetarian adolescents are as tall or taller than omnivores and are generally leaner, although final adult height may be reached at a later age87. Perry88 stated that vegetarian adolescents are twice as likely to consume fruits and vegetables, one-third as likely to consume sweets, and one-fourth as likely to consume salty snack foods once per day. This is supported by O'Brien89 who reported that current vegetarians in the younger and older cohorts had healthier dietary intakes than non- vegetarians with regard to fruits, vegetables, and fat. However adolescent vegetarians, especially adolescent males, have been found to be at high risk for engaging in unhealthy and often extreme weight loss behaviours90. This observation is corroborated with those who found that energy intakes of the vegetarian adolescents were well below the reference values (66%)91. Children who follow certain vegetarian diets, particularly vegan diets, are reported to have difficulty acquiring adequate energy intake92. Protein intake was higher in omnivores than in lacto-ovo-vegetarians but was still adequate for their weight93. However, Sanders and Reddy94 and Donovan and Gibson95 argued that total energy intakes were similar to those reported in non-vegetarian children. Lamisse96 also concluded that energy intake of lacto-ovo vegetarians was not significantly different from that of the omnivores, though slightly lower.

Dietary factors

Portion size and percentage of fat in the diet

The current obesogenic eating environment is characterized by convenient, relatively inexpensive, energy dense and highly palatable foods served in large portions. An increase in portion size of foods in recent years have resulted in an “obesogenic” environmental influence for children by producing excessive intake at meals97,98. Though it is not clear why children are more influenced by portion size as they age, Ello-Martin et al.99 reported that portion size influences the development of hunger and satiety with higher levels of overeating. Thus, when offered bigger portions, subjects ate a larger amount before they reached satiation100. To support this statement, a significant relationship between the amount of food provided and energy intake was observed whereby subjects consumed 30% more energy (676 kJ) when offered the largest portion than when offered the smallest portion101. The combined effects of high-energy density and large portion size may also lead to excess energy intakes and body weight gain102. On the other hand, smaller bite sizes or pauses within meals have been associated with reduced energy intake in some studies98, or conversely have led to no differences in overall energy intake103. The latter reported that energy intake during a fast food meal was not influenced by portion sizes. Therefore, it can be argued that other inherent characteristics such as the nutritional composition, palatability, high fat content of conventional fast food are more likely to promote excess energy intake. In general foods that are high in fat tend to be energy dense, highly palatable and promote overconsumption, hence leading to excess energy intake and eventually weight gain104. Astrup et al.105 argued that reduced fat diets consistently results in a reduced total energy intake and reduced weight gain. Fats also carry many aromatic compounds that add flavour to foods and, therefore, high fat foods may be overconsumed. Adolescents tend to exceed the recommendation for fat intake (32% to 40%)106. Swedish and Norwegian children and adolescents have the lowest fat intake in Europe (30–33%), whereas Spain, Greece and UK have the highest (>40%)107. This trend persists in developing countries whereby percentage of fat was 25.6g/day for Tanzanian adolescent girls108 while in India the majority had percentage fat intake well below the RDA28.

Snacking and meal skipping

Adolescents develop their own values, including values relating to food and meals109. The eating pattern of adolescents has changed rapidly towards the trend of increased snacking and high-fat food intake, and greater frequency of eating outside the home or meal skipping110. Adolescent girls are more likely to skip breakfast than adolescent boys111. Shils et al.2 reported that approximately 20% of adolescents skip breakfast each day. Breakfast calories have the greatest influence on daily energy intake and skipping breakfast is associated with lower total daily intake112. Moreover, girls with irregular breakfast and lunch intake had higher percent of energy from in-between meals (19% from ‘snack food') and less healthy food choice including lower intake of milk, vegetables, brown bread. They also consume more soft drinks and sweets compared to girls with regular meal pattern113. Snacks contribute 30% increase in the amount of daily energy, 612 Kcal/day in114. In 2005–2006, higher snacking frequency was associated with higher total calorie intake115. Adolescents who had 4 or more snacks in a day consumed over 1.5 times as many calories as did adolescents who reported no snacks116. Sonoo et al.24 reported that snacking was highly prevalent (84%) and occurred more often in female teens, urban residents and middle and higher income groups while Bargiota et al.27 observed that about half of the adolescents purchased a snack daily from the school canteen and half of them had an afternoon snack out with peers.

Study limitations

Most of the studies assessed relied on self-reported data and cross-sectional study designs with descriptive statistics. There were difficulties to compare findings of reviewed studies due to differences in study designs, methods of data collection and characteristics of samples participants. To obtain more comprehensive information on the predictive determinants affecting energy intake, more longitudinal studies are needed. In addition, future research should possibly adopt measurement approaches that use both self-report and objective measurements to measure predictive factors and determinants of energy intake more accurately. Some studies used theoretical framework which are important to identify behavior change and enabling development of effective interventions among youth. Most of the research studies did not assess the effects among the variables or the direction of their effects. Assessing determinants of eating habits and energy intake objectively is a topic of recent interest117. Limited studies on determinants of environmental factors on snacking which are linked to energy intake were found and this may be because the role of physical environment is of recent interest118.

Conclusion

The factors discussed in the present systematic review are namely physical activity level, socioeconomic status, diet ,individual and social factors which do have an impact on energy intake and eating habits. Obviously, there are other factors not discussed here such as the genetic factor, basal metabolic rate (BMR), and total energy expenditure (TEE) to name but a few. All the examples and studies in this study revealed clear patterns towards nutritional behaviours of adolescent girls. As evident in this review, there are mixed results regarding the impact of the different factors on subsequent energy intake. To conclude, it is a dire need to consider these factors when designing nutritional interventional programs so as to prevent shortterm health problems and chronic disease in adulthood. The goal is not to change behaviour of all but to increase the percentage of people adopting healthier lifestyle and eating habits.
