Abstract

Background.

As reported from studies conducted in Nepal, between 15% and 57% of adults had ever consumed alcohol and between 1.5% and 25% of adults have alcohol use disorders (AUD). Few studies in Nepal have identified the correlates of consumption or described the help-seeking patterns and stigma among those affected with AUD.

Methods.

Interviewers administered the Alcohol Use Disorders Identification Test (AUDIT) as part of population-based surveys of adults in Chitwan District between 2013 and 2017. We conducted a secondary analysis to identify sociodemographic and health-related correlates of recent alcohol consumption using the χ2 test, to identify correlates of total AUDIT scores among men who drink using negative binomial regression, and to describe the treatment-seeking and stigma beliefs of men with AUD.

Results.

Over half (53.7%, 95% CI 50.4–57.0) of men (n  =  1130) recently consumed alcohol, and there were associations between being a drinker with age, religion, caste, education, occupation and tobacco use. Nearly one in four (23.8%, 95% CI 20.2–27.8%) male drinkers screened positive for AUD, and AUDIT scores were associated with age, caste, marital status, occupation, tobacco use, depression, functional status and suicidal ideation. Few (13.3%, 95% CI 11.7–15.0) women (n  =  2352) recently consumed alcohol, and 5.3% (95% CI 3.0–9.1) of female drinkers screened positive for AUD. Among AUDIT-positive men, 38% spoke to another person about their problems and 80% had internalized stigma.

Conclusions.

This study revealed that nearly one in four men who drink likely have AUD. Higher AUDIT scores were associated with depression, suicidality, dysfunctionality and internalized stigma.

Background

Alcohol is responsible for over 5% of global burden of disease and injury (World Health Organization, 2014). Across Nepal, alcohol use varies widely: various studies have estimated that between 15% and 57% of adults had ever consumed alcohol (Dhital et al. 2001; Chataut et al. 2011; Lee et al. 2011; Manandhar et al. 2012; Luitel et al. 2013; Aryal et al. 2014; World Health Organization, 2014) and between 1.5% and 25% of adults have behaviours consistent with alcohol use disorders (AUD) (Jhingan et al. 2003; World Health Organization, 2014; Aryal et al. 2015). Similar to other low-income countries, Nepal, prior to 2014, lacked a national strategy to reduce harmful alcohol use (Riley & Cowan, 2014; World Health Organization, 2014). Yet, emerging evidence (Benegal et al. 2009; Nadkarni et al. 2017) demonstrates that it is effective and cost-effective to deliver treatment such as Brief Intervention (Babor & Higgins-Biddle, 2001) for harmful alcohol use at the primary care level in low- and middle-income countries.

Epidemiologic studies conducted in Nepal have characterized the burden and consequences of alcohol consumption in the community (Katz et al. 2003; Tausig et al. 2004; Ho-Yen et al. 2007; Kulkarni et al. 2010; Chataut et al. 2011; Lee et al. 2011; Oshiro et al. 2011; Manandhar et al. 2012; Bam et al. 2013; Khan et al. 2013; Adhikari et al. 2014; Vaidya & Krettek, 2014; Atteraya et al. 2015), and clinical studies have characterized the consumption histories of hospitalized patients (Shyangwa et al. 2009; Subba et al. 2010; Bam et al. 2011; Maskey et al. 2011a, b; Pradhan et al. 2012; Gyawali et al. 2013), but few population-based studies in Nepal have identified the correlates of alcohol consumption in the population, or have described the help-seeking patterns and barriers among those whose drinking patterns are consistent with AUD. Understanding alcohol consumption patterns will inform community engagement efforts and case detection, and with treatment provision in the public sector.

In this secondary analysis, we have described the alcohol-related features of adults in Chitwan District, Nepal, specifically relating to recent alcohol consumption and severity of alcohol use problems, and the internalized stigma beliefs of men with AUD.

Methods

Setting

Nepal is classified as a low-income state (Cosic et al. 2017), with a human development rank of 144 and life expectancy of 70 years (United Nations Development Programme, 2016). Chitwan District is in central Nepal near the India border. A relatively affluent district, the literacy rate is 77% (Central Bureau of Statistics, 2014), compared to the national average of 57% (UNDP, 2015). As of 2014, no evidence-based services for hazardous or harmful alcohol use were available in the primary health care sector Chitwan. The nearest detoxification and rehabilitation services for people who were dependent on alcohol were available in the district headquarters.

The Programme to Improve Mental Health Care (PRIME) consortium aims to improve the accessibility of treatment by integrating mental health services into the primary health care sector in low- and middle-income country settings (Lund et al. 2012). In consultation with Nepal Ministry of Health officials, 10 Village Development Committees (VDC) in Chitwan District, with a total population of 108 369 (Central Bureau of Statistics, 2014) were selected for the initial stage of the PRIME implementation (Jordans et al. 2016).

Study design and sampling

Details of the PRIME Community Study, including the sampling plan, recruitment and questionnaire design were previously reported (Rathod et al. 2016). The primary aim of the Community Study was to estimate a change in population-level treatment coverage for depression and for AUD in Chitwan District, coinciding with the implementation of a district-level mental health care plan (Jordans et al. 2016). This secondary analysis of the Community Survey dataset – described in brief below – specifically concerned the correlates of alcohol use. Two survey rounds were completed (n  =  1983 in May–August 2013 and n  =  1499 in December 2016–March 2017), which was set to have 80% power to detect an increase in coverage from 5% to 25%. At each survey round, fieldworkers used sampling frames consisting of households enumerated by the VDC authorities and used a computer programme to select households randomly. The fieldworkers approached a member of selected households, took an inventory of adults (inventory participation rate 100%), wrote the adults’ names on individual pieces of paper, mixed up the pieces and asked a family member to pick one piece as a means of selecting the adult for recruitment into the study (consent rate 99%). An adult was eligible to participate if they were resident of the household and age 18 years or more, and ineligible if they were intellectually incapable of providing informed consent. For this secondary analysis, all participants were included, and unless otherwise indicated the data from both survey rounds were pooled. There were no missing data.

Data collection

With participating adults, the fieldworker orally administered a Nepali-language-structured interview using a questionnaire application programmed on an Android tablet. All participants completed the questionnaire sections about basic sociodemographic characteristics, tobacco use, AUD screening, and depression screening and suicidality. Participants who were identified as AUD cases or depression cases completed disorder-specific sections about who they spoke to about the problems, and about their internalized stigma beliefs. To facilitate secondary analyses such as for this report while reducing data collection burden, selected participants completed an extended version of the questionnaire, which included sections on sociodemographic characteristics, household socioeconomic status, hospitalization and functional status. These sections were completed by all screen-positive participants and by 10% of screen-negative participants who were selected through a random number generator in the questionnaire application.

Study measures

The tobacco and alcohol use section contained questions about current tobacco use, lifetime alcohol use and the 10-item Alcohol Use Disorders Identification Test (AUDIT) (Babor et al. 2001). Prior to any questions about alcohol, the questionnaire application included a script for the fieldworker to read to women and Brahmin/Chhetri caste members, acknowledging that traditionally members of these groups did not consume alcohol but that habits have changed. The AUDIT has been widely used to screen individuals for AUD for research purposes, and has been validated in Nepal (Pradhan et al. 2012). From the total AUDIT score, we considered a person with a score of 0 to be abstinent, ≥1 to be a recent (within 12 months) consumer of alcohol; and, using World Health Organization guidelines (Babor et al. 2001), we considered a score of ≥8 to be a positive screen for AUD, inclusive of the following sub-categories: 8–15 to be indicative of hazardous drinking patterns, 16–19 of harmful drinking and ≥20 of dependent drinking.

To screen for depression, we used the total score of the Patient Health Questionnaire (PHQ9) screening tool (Kroenke et al. 2001), which has been validated in Nepal (Kohrt et al. 2016). A score of 10 or more was a positive screen. For suicidal ideation, we adapted a question from the Composite International Diagnostic Interview (Robins et al. 1988), and question about hospitalization in the past 12 months was drawn from the Client Service Inventory Receipt (Beecham & Knapp, 2001).

PHQ9 and AUDIT screen-positive participants were asked 11 questions from the Internalized Stigma of Mental Illness (Boyd Ritsher et al. 2003) measure, and those who had responses of ‘agree’ or ‘strongly agree’ were considered to have that internalized stigma belief. To assess household economic status, we asked questions drawn from the Nepal Demographic and Health Survey [Ministry of Health & Population (MOHP) [Nepal] et al. 2012] about drinking water source, toilet access, housing amenities and household assets. We entered the dummy coded economic variables into principle components analysis using the method described by Vyas & Kumaranayake (2006) and created three equally proportioned groups from the sum of first factor weights.

We created tertiles from the World Health Organization Disability Assessment Schedule (Üstün et al. 2010) total score to create categories of functional status. For the question about religion, we created categories of Hindu, Buddhist and other. For caste, we combined Magar, Gurung, Newar and Tamang into a single ‘Janajati’ group, as these groups share important cultural characteristics. For marital status, we combined those who were separated, divorced or widowed into a single group of people who were post-marital. For occupation, we combined service and business workers into a group, and all other non-agricultural occupations into a group.

Ethics

Fieldworkers gave adults written and oral information about the study and adults were asked if they had questions about the study before deciding to participate. Literate adults provided written confirmation of consent, while – due to cultural consideration against use of fingerprinting – illiterate adults provided verbal confirmation of consent. Participants who provided affirmative responses to questions about suicidality were referred to psychosocial counsellors who were mobilized as part of PRIME. The study protocol and consent procedures were approved by institutional review committees of the Nepal Health Research Council (Kathmandu, Nepal), World Health Organization (Geneva, Switzerland) and the University of Cape Town (South Africa).

Statistical analysis

As a secondary analysis, the choice of characteristics for this analysis was guided by availability from the study questionnaire. First, we summarized the sociodemographic (i.e. age, occupation, caste, religion, marital status, household economic status) and health-related (i.e. tobacco use, depression score, functional status, suicidal ideation, hospitalization) characteristics separately for men and women in the study. Within each category, we reported the proportion of participants who had recently consumed alcohol and tested for associations using the Pearson's χ2 test. We noted when χ2 p < 0.05. Second, separately for men and women, we reported the proportion who had AUD (AUDIT score ≥8) and who were dependent on alcohol (AUDIT score ≥20). For the rest of the analysis, we limited the sample to men: though many women in Nepal consume alcohol (Dhital et al. 2001), the frequency and intensity of their consumption is substantially lower than for men (Riley & Cowan, 2014; Aryal et al. 2015), which was observed for this sample in a previous report (Rathod et al. 2016).

Third, among men who recently consumed alcohol (AUDIT ≥1), we assessed whether any sociodemographic or health-related characteristics were associated with AUDIT scores. As the dependent variable (AUDIT score) distribution was right skewed, we could not use linear regression, and instead, we used negative binomial regression (Elhai et al. 2008) to estimate the mean AUDIT score and 95% confidence interval for each category of the characteristic. We used a separate regression model for each characteristic of interest. We noted when the regression model's F test had p < 0.05, indicating evidence of an association for the characteristic with the AUDIT score. Finally, we tabulated the proportion of men with AUD who ‘agree’ or ‘strongly agree’ with 11 internalized stigma beliefs.

We conducted the analysis in Stata 14.1 (College Station, TX, USA). An additional text file contains the Stata code for this analysis (see Additional file 1). Aside counts, we adjusted all figures reported here for the population-based sampling design and sampling probability weights.

a

Assessed among participants who screened positive for depression or screened positive for alcohol use disorder, and a randomly selected 10% sub-sample of participants who screened negative for both.

Within the total sample of 3482, 36% were men and 64% were women. Among men, 53.7% (95% CI 50.4–57.0) had recently consumed alcohol. A quarter (25.0%) of men were aged between 18 and 29 years, and of these men, 52.4% recently consumed alcohol. Another 17.8% were aged 30–39 years, and of these, 65.2% recently consumed alcohol. Over half (51.6%) of men were in the Brahmin or Chhetri caste group, and 35.7% of these men recently consumed alcohol. Drinking was more likely among men from Janajati (68.0%), Dalit (80.0%) or other (77.2%) castes. There was evidence of association for drinking alcohol by category of age, religion, caste, education, occupation and tobacco use (all p < 0.05). Among women, 13.3% (95% CI 11.7–15.0) had recently consumed alcohol. Nearly a third (31.9%) of women were aged between 18 and 29 years, and 6.8% of these women recently consumed alcohol. Another 13.3% of women were aged between 50 and 59 years, and 21.9% of these women recently consumed alcohol. Almost half (48.9%) of the women were in the Brahmin or Chhetri caste, and 2.3% of these women recently consumed alcohol. Of the remaining caste groups, between 19.7% and 26.9% of women recently consumed alcohol. There was evidence of association for drinking alcohol by category of age, religion, caste, marital status, education, economic group, tobacco use, depression severity and suicidal ideation (all p < 0.05).

Of the men who recently consumed alcohol, nearly one in four (23.8%, 95% CI 20.2–27.8%) had AUD (AUDIT score ≥8), which is inclusive of 15.3% who had hazardous drinking, 3.1% with harmful drinking and 5.4% with dependent drinking. Of the women who recently consumed alcohol, 5.3% (95% CI 3.0–9.1) had AUDIT scores consistent with AUD, inclusive of 4.2% with hazardous drinking, 0.3% with harmful drinking and 0.3% with dependent drinking.

There were no missing data.

a

Assessed among participants who screened positive for depression or screened positive for alcohol use disorder, and a randomly selected 10% sub-sample of participants who screened negative for both.

Overall, the mean AUDIT score for men who consumed alcohol was 5.5 (95% CI 4.9–6.1). There was evidence of an association between age group and AUDIT scores, ranging from a mean AUDIT score of 3.5 for men aged 18–29 to a mean AUDIT score of 6.9 for men aged 40–49. AUDIT scores were inversely associated with educational attainment, with a mean score of 7.0 for men with less than primary education to 3.4 for men who completed secondary education. A similar association was evident for economic group. AUDIT scores were especially high among men who were tobacco users (mean 7.2), who screened positive for depression (mean 16.9), had lower functional status (mean 8.7) or had suicidal ideation in the past 12 months (mean 13.8).

Talking about problems and internalized stigma

Among AUDIT-positive men, only 38% spoke to at least one other person about problems with alcohol. Of the men who spoke to another person, they were most likely to speak to a spouse/partner (64%), friend or neighbour (60%), or another family member (30%).

The internalized stigma beliefs of men with AUD are presented in Table 3.

Per cent figures sum to more than 100% because participants could agree with more than one statement.

There were no missing data.

Counts are reported as observed, while percentage figures are design-adjusted.

Nearly half (45.6%) of the men with AUD say they would either ‘agree’ or ‘strongly agree’ that ‘I am disappointed in myself’. Men with AUD were also likely to agree that ‘These problems have spoiled my life’ (42.7%) or that ‘Others think I can achieve much in life’ (40.1%). Nearly one in five men with AUD (19.4%) did not agree with any of the statements.

Discussion

Consumption of alcohol was largely a male habit in Chitwan District; among women, its use was concentrated among specific subgroups. Among men who drink, AUDIT scores were positively associated with suicidality, depression and dysfunction, and among men with AUD, feelings of internalized stigma were common. Much of the data concerning alcohol use in Nepal were generated from studies which investigated the burden and consequences of alcohol use (Katz et al. 2003; Tausig et al. 2004; Ho-Yen et al. 2007; Kulkarni et al. 2010; Chataut et al. 2011; Lee et al. 2011; Oshiro et al. 2011; Manandhar et al. 2012; Bam et al. 2013; Khan et al. 2013; Adhikari et al. 2014; Vaidya & Krettek, 2014; Atteraya et al. 2015), or were based on AUD patients in tertiary care facilities (Shyangwa et al. 2009; Subba et al. 2010; Bam et al. 2011; Maskey et al. 2011a, b; Pradhan et al. 2012; Gyawali et al. 2013); these data offer a more complete picture of the population-level epidemiologic features of alcohol use in Nepal.

The prevalence of recent alcohol consumption in Chitwan District provides further evidence of the wide variation of drinking prevalence across Nepal. Findings from where community-based studies in Nepal are that between 18% and 71% of men (Dhital et al. 2001; Oshiro et al. 2011; Luitel et al. 2013; Vaidya & Krettek, 2014; Atteraya et al. 2015) and 6.8–28% of women (Dhital et al. 2001; Katz et al. 2003; Kulkarni et al. 2010; Khan et al. 2013; Luitel et al. 2013; Vaidya & Krettek, 2014) recently drank alcohol. As observed here, a majority (54%) of all men drank alcohol in the past 12 months, and the behaviour was widespread across sub-groups: men between 60 and 88 years of age were least likely (31%) to drink and Dalit caste members were most likely (80%).

Among women, there were notable variations within subgroups: though 13% of all women in Chitwan were recent drinkers, the probability of drinking was substantially higher for women who used tobacco, screened positive for depression or had suicidal ideation (all >23%). These associations are suggestive of alcohol use as self-medication for mental distress, a hypothesis which can be explored with qualitative methods. Though it is not possible to establish the causal direction between alcohol use and factors such as education and economic status, the associations observed here highlight how the role of alcohol must be considered as part of any discussion of social development. Further research can establish whether drinking behaviour becomes more common among all women or within specific subgroups, and thus inform alcohol education programmes.

We found evidence that AUDIT scores were inversely associated with wellness among male drinkers. Higher AUDIT scores were evident among male drinkers who used tobacco, experienced suicidal ideation and had higher levels of dysfunction and depression. Other studies from Nepal have found alcohol use to be positively associated with sexual risk taking (Poudel et al. 2004; Bam et al. 2013), hypertension (Chataut et al. 2011; Khan et al. 2013), psychological disorders (Tausig et al. 2004), physical inactivity (Vaidya & Krettek, 2014), tuberculosis infection (Gyawali et al. 2013) and betel-quid dependency (Lee et al. 2012). In this district of Nepal, while only 5% of men with AUD sought treatment specifically for problems with alcohol (Rathod et al. 2016), it is likely that a substantial proportion of men with AUD accessed health care for these other health problems. As has recently been demonstrated in India, general service providers can offer effective counselling (Nadkarni et al. 2017). By addressing the alcohol problem first, the service provider will improve the prognosis for the co-morbid condition. For men with AUD who are not accessing health care, a more pro-active approach such as community-informed referral may be appropriate, and has been recently demonstrated as feasible and effective in Chitwan (Jordans et al. 2015).

Also notable was the pattern of alcohol consumption by age, education and household economic status. Over 60% of men aged 30–59 years consumed alcohol (v. 52% for 18–29 years and 31% for 60–88 years), and the AUDIT score for drinkers peaks at a mean of 7.0 for those aged 40–49 years and slightly declines thereafter. Further research can investigate the life course factors (e.g. marriage, becoming head of household) which lead men to drink more heavily in middle age. For education, men with highest level of education were least likely to drink, and those who did drink had lower AUDIT scores. Though alcohol consumption was consistent by economic status, there was an inverse association with AUDIT scores. The inverse association has been observed consistently in high-income countries, with fewer data available in low- and middle-income settings (Blas et al. 2010); available evidence underpinning conceptual models highlight how low socioeconomic status is both a risk factor and a consequence of alcohol consumption (Blas et al. 2010; World Health Organization, 2014).

Globally, health service utilization for mental health disorders varies by area and by the specific disorder; utilization is least likely for adults in low-income countries and for alcohol problems (Kohn et al. 2004). This pattern was confirmed in Chitwan, where only 5% of AUDIT-positive adults sought treatment for their problems (Rathod et al. 2016). Accordingly, clinic-based health promotion programmes are likely to have limited effect on alcohol treatment coverage in a low-income setting such as Nepal. In Chitwan, 38% of men with AUD discussed their alcohol problems with another person, and often to a friend or neighbour, and as such there is potential to promote treatment seeking through community-informed referral (Jordans et al. 2015). For the 62% of men with AUD who do not discuss their problems with others, further exploration of the internalized stigma beliefs is warranted. Most men with AUD (81%) endorsed at least one internalized stigma belief. It is possible that community sensitization programmes can create awareness that alcohol problems are not indicative of a personal failing, that alcohol habits are modifiable, and that discussion with a health care provider can help. Developing effective community sensitization programmes remains a key research goal for addressing the treatment gap.

This study was unique in Nepal in that it was a large community-based survey of men and women conducted over a large geographic area, with a population-based sampling design and analysis. We used a widely validated screening tool to measure alcohol use, which facilitates comparison across settings. However, this study also has important limitations. As a secondary analysis, the choice of characteristics for this analysis was guided by availability from the study questionnaire, and there may be other important risk groups for alcohol use which were not investigated here. Like many areas of Nepal, Chitwan District has a high level of seasonal labour migration (Bohra & Massey, 2009; Central Bureau of Statistics, 2014), and so we are likely to have undersampled men in this study. Male migrants are a notable risk group with regard to alcohol (Poudel et al. 2004; Bam et al. 2013) and who were less likely to be captured in this study. Though our interviewers had a special script to sensitize participants who belonged to traditionally abstinent groups (i.e. women and members of the Brahmin caste), we must also note the high levels of internalized stigma observed among those with AUD likely prevented other drinkers from acknowledging their drinking, leading to an underestimate of the prevalence of alcohol consumption. Finally, as a cross-sectional study measuring the prevalence of drinking behaviours across the population, the correlations found here are not intended to be interpreted as causal factors but as factors to inform health service provision and health promotion planning. Future research using longitudinal designs can identify the risk factors for developing AUD and can inform the development of prevention strategies.

A priority-setting exercise with expert stakeholders in Nepal came to a consensus that the burden, severity and treatability of AUD made it a strong candidate for provision of treatment services (Jordans et al. 2013). This study provides support for the assumptions about burden and severity, in that a large proportion of men who drink have AUD, and there is a confluence of depression, suicidality and dysfunctionality among men who drink more heavily. As AUD treatment services have now been developed (Jordans et al. 2016) and integrated into the primary health care sector in Chitwan District, subsequent work must focus on promoting help seeking for men with AUD, and to monitor trends in alcohol consumption over time.
