Equity in household spending on alcoholic beverages in South Africa: assessing changes between 1995 and 2011.

BACKGROUND: Globally, alcohol consumption accounts for a substantial burden of disease, which translates into high social and economic costs. To address this burden, several policies (e.g. age and trading hour restrictions, increasing alcohol taxation) were implemented. Despite the existence of these policies evidence shows that alcohol misuse and alcohol-related harms have increased in South Africa over recent years. The objective of this paper is to assess progressivity and the changes in progressivity of alcohol expenditure at the household level in South Africa using datasets that span 15 years. METHODS: Data come from the 1995, 2000, 2005/06 and 2010/11 South Africa Income Expenditure Survey. Distribution of spending on alcoholic beverages were analyzed using standard methodologies. Changes in progressivity between 1995 and 2000, and between 2005/06 and 2010/11 were also assessed using the Kakwani index. RESULTS: Alcohol spending was regressive between 1995 and 2011 as the fraction of poorer households' expenditure spent on alcohol beverage exceeds that for the richest households. Also, the difference in Kakwani indexes of progressivity indicates that spending on alcoholic beverages has become less regressive between the same time periods. CONCLUSION: The results show no evidence that alcohol policy including taxation increased regressivity. Thus, there is an opportunity to further reduce the regressivity using coherent alcohol policies. This paper concludes that there is a need for further research to unpack why alcohol spending became less regressive over the years that goes beyond just looking at changes in the distribution of alcohol expenditure.

Missing knowledge of gendered power relations among non-governmental organisations doing right to health work: a case study from South Africa.

BACKGROUND: Despite 20 years of democracy, South Africa still suffers from profound health inequalities. Gender roles and norms are associated with individuals' vulnerability that lead to ill-health. For instance, gender inequality influences women's access to health care and women's agency to make health-related decisions. This paper explores gender-awareness and inclusivity in organisations that advocate for the right to health in South Africa, and analyses how this knowledge impacts their work? METHODS: In total, 10 in-depth interviews were conducted with members of The Learning Network for Health and Human Rights (LN), a network of universities and Civil Society Organisations (CSOs) which is explicitly committed to advancing the right to health, but not explicitly gendered in its orientation. RESULTS: The results show that there is a discrepancy in knowledge around gender and gendered power relations between LN members. This discrepancy in understanding gendered power relations suggests that gender is 'rendered invisible' within the LN, which impacts the way the LN advocates for the right to health. CONCLUSIONS: Even organizations that work on health rights of women might be unaware of the possibility of gender invisibility within their organisational structures.

Systematic Review of the Economic Evaluation of Returning Incidental Findings in Genomic Research.

Objectives: Discussions regarding who and how incidental findings (IFs) should be returned and the ethics behind returning IFs have increased dramatically over the years. However, information on the cost and benefits of returning IFs to patients remains scanty. Design: This study systematically reviews the economic evaluation of returning IFs in genomic sequencing. We searched for published articles on the cost-effectiveness, cost-benefit, and cost-utility of IFs in Medline, Scopus, PubMed, and Google Scholar. Results: We found six published articles that met the eligibility criteria of this study. Two articles used cost analysis only, one used cost-benefit analysis only, two used both cost analysis and cost-effectiveness, and one used both cost-benefit analysis and cost-utility to describe the cost of returning IFs in genomic sequencing. Conclusion: While individuals value the IF results and are willing to pay for them, the cost of returning IFs depends on the primary health condition of the patient. Although patients were willing to pay, there was no clear evidence that returning IFs might be cost-effective. More rigorous economic evaluation studies of IFs are needed to determine whether or not the cost of returning IFs is beneficial to the patient.

Assessing Intertemporal Socioeconomic Inequalities in Alcohol Consumption in South Africa.

Background: This paper assesses changes in the socioeconomic inequality in alcohol consumption by exploring whether alcohol consumption (current and binge drinkers) is more prevalent among the wealthier (pro-rich) or poorer (pro-poor) group over time. Methods: Data come from the 2008, 2010/11, 2012, and 2014/15 waves of the National Income Dynamics Study (NIDS). Various equity stratifiers (sex, age, race, and rural/urban) are used to analyze the prevalence of alcohol consumption and to investigate differences in socioeconomic inequalities. Changes in socioeconomic inequality in alcohol consumption between 2008 and 2014/15 were also assessed using the concentration index. Results: Current drinkers were more concentrated among richer South Africans, while binge drinkers were concentrated among the poorer population. For current drinkers, irrespective of sex, race, age, and urban, socioeconomic inequality in alcohol consumption had become less pro-rich between 2008 and 2014/15; while inequality in binge drinking, outside of the Asian/Indian and rural categories, had become less pro-poor between 2008 and 2014/15. Conclusion: The results show evidence that binge drinking is a bigger problem among those of low-SES, young individuals, male and African populations. This paper concludes that the SA government should continue to push forward policies aiming to reduce the prevalence of binge drinking.

Usability of existing alcohol survey data in South Africa: a qualitative analysis.

OBJECTIVE: This paper assesses the usability of existing alcohol survey data in South Africa (SA) by documenting the type of data available, identifying what possible analyses could be done using these existing datasets in SA and exploring limitations of the datasets. SETTINGS: A desktop review and in-depth semistructured interviews were used to identify existing alcohol surveys in SA and assess their usability. PARTICIPANTS: We interviewed 10 key researchers in alcohol policies and health economics in SA (four women and six men). It consisted of academic/researchers (n=6), government officials (n=3) and the alcohol industry (n=1). PRIMARY AND SECONDARY OUTCOME MEASURES: The desktop review examined datasets for the level of the data, geographical coverage, the population surveyed, year of data collection, available covariables, analyses possible and limitations of the data. The 10 in-depth interviews with key researchers explored informant's perspective on the usability of existing alcohol datasets in SA. RESULTS: In SA, alcohol data constraints are mainly attributed to accessibility restrictions on survey data, limited geographical coverage, lack of systematic and standardised measurement of alcohol, infrequency of surveys and the lack of transparency and public availability of industry data on production, distribution and consumption. CONCLUSION: The International Alcohol Control survey or a similar framework survey focusing on substance abuse should be considered for implementation at the national level. Also, alcohol research data funded by the taxpayers' money and alcohol industry data should be made publicly available.

Validity and reliability of maternal recall of pregnancy history and service use among signing Deaf women: a cross-sectional descriptive study from South Africa.

INTRODUCTION: There is little credible quantitative data on pregnancy histories and outcomes for disabled women in low-income and middle-income countries. The purpose of this study, based in Cape Town, South Africa, was to test the reliability and validity of maternal recall of pregnancy history and service use among a sample of Deaf women who use South African Sign Language (SASL). METHODS: We interviewed 42 signing Deaf women of childbearing age (18-49 years) in SASL using a structured questionnaire in July 2016. To assess reliability, seven participants (16% of the sample) were reinterviewed by different interviewers under the same conditions after 10-30 min. For the analysis we used (1) Cohen's kappa, an inter-rater statistical method, and (2) overall percentage agreement. Validity was explored by comparing the participants' pregnancy history to the Western Cape Provincial Health Data Centre (PHDC) database. RESULTS: The reliability results showed that out of 19 questions 14 demonstrated substantial to perfect agreement kappa scores (kappa between 0.61 and 1) and 5 had the lowest kappa agreement scores (kappa <0.61). With respect to percentage agreement, participants provided identical responses in 87% cases. Overall, women provided more reliable responses to pregnancy outcomes compared with demographic information. Validity results showed that 29 out of 35 Deaf women provided survey responses that matched or nearly matched (83% agreement) the PHDC database for birth history and delivery location. CONCLUSION: This study suggests that for this sample of signing Deaf women recall of pregnancy history and service use is reliable and valid. Extending this approach to other similar populations will require further research, but it is important that methods to access hard-to-reach disabled populations are developed so that health system responsiveness to marginal populations can be based on robust evidence.
