Anemia in Low-Income Countries Is Unlikely to Be Addressed by Economic Development Without Additional Programs

Harold Alderman; Sebastian Linnemayr

Although governments may decline to invest in iron fortification or supplementation influenced by the view that income growth will address the problem, the data do not support this view. Looking at the rates of anemia among children and adult women across 40 Demographic and Health Surveys from 32 countries, this study found that although anemia rates do decrease as income increases, the decrease is modest. Indeed, overall anemia rates decline roughly a quarter as fast as income increases and at only half the speed at which rates of underweight decline.

This paper presents one of the first qualitative studies to discuss programmatic barriers to SMS-based interventions for HIV-positive youth and discusses pathways through which youth perceive them to work. We conducted six focus groups with 20 male and 19 female HIV-positive youths in two clinics in Kampala, Uganda. We find that youth commonly use SMS as over 90% of this study’s youths knew how to read, write and send messages and almost three-fourths of them had phones. Youth strongly felt that the success of this intervention hinged on ensuring confidentiality about their HIV-positive status. Key programmatic challenges discussed where restrictions on phone use and phone sharing that could exclude some youth. Participants felt that the intervention would improve their adherence by providing them with needed reminders and social support. Youths’ suggestions about intervention logistics related to content, frequency, timing and two-way messages will be helpful to practitioners in the field.

Optimal strategies to improve food security and nutrition for people living with HIV (PLHIV) may differ in settings where overweight and obesity are prevalent and cardiovascular disease risk is a concern. However, no studies among PLHIV have investigated the impact of food support on nutritional outcomes in these settings. We therefore assessed the effect of food support on food insecurity and body weight in a population of PLHIV with high prevalence of overweight and obesity. We implemented a pilot intervention trial in four government-run HIV clinics in Honduras. The trial tested the effect of a monthly household food ration plus nutrition education (n = 203), compared to nutrition education alone (n = 197), over 12 months. Participants were clinic patients receiving antiretroviral therapy (ART). Assessments were obtained at baseline, 6 and 12 months. Primary outcomes for this analysis were food security, using the validated Latin American and Caribbean Food Security Scale and body weight (kg). Thirty-one percent of participants were overweight (22%) or obese (8%) at baseline. At 6 months, the probability of severe food insecurity decreased by 48.3% (p < 0.01) in the food support group, compared to 11.6% in the education-only group (p < 0.01). Among overweight or obese participants, food support led to average weight gain of 1.13 kg (p < 0.01), while nutrition education alone was associated with average weight loss of 0.72 kg (p < 0.10). Nutrition education alone was associated with weight gain among underweight and normal weight participants. Household food support may improve food security but not necessarily nutritional status of ART recipients above and beyond nutrition education. Improving nutritional tailoring of food support and testing the impact of nutrition education should be prioritized for PLHIV in Latin America and similar settings.

HIV medical care, including antiretroviral therapy (ART), is often successful in restoring physical health and functioning. But in developing countries, HIV medical care is often insufficient to achieve social and economic health, and hence innovative economic support programs are much needed. We conducted semistructured interviews with 30 adults receiving ART and microcredit loans operated by Uganda Cares. Using content analysis, we explored the impact of the microcredit loans on the economic, social, and psychological well-being of respondents. Most respondents indicated that the microcredit loans played a positive role in their lives, helped them to keep their children in school and sustain their families, and improved their self-esteem and status in the community. In addition, we also found significant positive knowledge spill-over and network effects in the program with regard to business management and support. However, more than half of the participants indicated experiencing repayment problems either personally or with other group members due to unexpected emergencies and sickness. These findings highlight that microcredit programs have the potential of being an economic support system for HIV clients trying to reestablish their livelihoods, especially in resource-constrained settings, though more research is needed to determine the overall economic viability of such programs.

Objectives To assess the effectiveness of Short Message Service (SMS) reminder messages on antiretroviral and cotrimoxazole prophylaxis adherence among HIV-positive youths as well as the relative effectiveness of SMS with and without a response option. Methods Eligible HIV-positive patients aged 15 to 22 years at 2 HIV clinics in Kampala, Uganda, participated in a year-long parallel individual-randomized controlled trial and were assigned in a 1-to-1-to-1 ratio to a weekly SMS message group, weekly SMS message with response option group, or a usual-care control group. Results We enrolled 332 participants. Electronically measured mean adherence was 67% in the control group, 64% in the 1-way SMS group (95% confidence interval [CI] = 0.77, 1.14), and 61% in the 2-way SMS group (95% CI = 0.75, 1.12) in an intent-to-treat analysis. Results for secondary outcomes and complete-case analysis were similarly statistically insignificant across groups. Conclusions Despite previous evidence that interventions using SMS reminders can promote antiretroviral therapy adherence, this study shows that they are not always effective in achieving behavior change. More research is needed to find out for whom, and under what conditions, they can be beneficial. Trial registration ClinicalTrials.gov identifier: NCT00830622.

Background More than half of those newly infected with HIV are young people yet youths have lower medication adherence than adults. Short message service (SMS) based interventions have demonstrated their effectiveness in improving adherence among adults in resource limited settings, but their efficacy with youths has not been studied. This study is one of the first qualitative studies to explore youths view on strategies for best implementing SMS based interventions.

Behavioral economic incentives to improve adherence to antiretroviral medication.

Sebastian Linnemayr; Chad Stecher; Barbara Mukasa

Objective: Fixed incentives have been largely unsuccessful in improving adherence to antiretroviral medication. Therefore, we evaluate whether small incentives based on behavioral economic theory can increase adherence to antiretroviral medication among treatment-mature adults in Kampala, Uganda. Design: A randomized control trial design tests whether providing small incentives based on either attending timely clinic visits (intervention group 1) or achieving high medication adherence (intervention group 2) can increase antiretroviral adherence. Antiretroviral adherence is measured by medical event monitoring system (MEMS) caps. Methods: Overall, 155 HIV-infected men and women age 19–78 were randomized into one of two intervention groups and received small prizes of US

1.50 awarded through a drawing conditional on either attending scheduled clinic appointments or achieving at least 90% antiretroviral adherence. The control group received the usual standard of care. Results: Preliminary results based on pooling the intervention groups showed individuals receiving incentives were 23.7 percentage points more likely to achieve 90% antiretroviral adherence compared with the control group [95% confidence interval (CI), 6.7–40.7%]. Specifically, 63.3% (95% CI, 52.9–72.8%) of participants in the pooled intervention groups maintained at least 90% mean adherence during the first 9 months of the intervention, compared with 39.6% (95% CI, 25.8–54.7%) in the control group. Conclusion: Small prize incentives resulted in a statistically significant increase in antiretroviral adherence. Although more traditional fixed incentives have not produced the desired results, these findings suggest that small incentives based on behavioral economic theory may be more effective in motivating long-term adherence among treatment-mature adults.

This study evaluates the impact of antiretroviral treatment (ART) on employment-related outcomes using prospective, longitudinal analysis. Starting in January 2008, 602 treatment-naïve clients in one rural clinic and in one clinic in the capital Kampala were interviewed about their medical history, and psychosocial and socioeconomic adjustment at baseline and at months 6 and 12. Half of the sample was eligible to receive ART, while the other half was also in HIV care, but not yet eligible for ART, therefore providing a comparison group that is similar to the treatment group in that its members are HIV-positive and have made the decision to enroll in HIV care. We found improvements in general health, reduction in the incidence of pain and health interfering with work, as well as improvements in work-related self-efficacy for both groups over time, but significantly more so for the group receiving ART treatment. At baseline, less than half of the people in the ART group worked, but after 6 months more than three quarters of them were working, surpassing the fraction of people working in the control group after 1 year. Another key finding of the study was the importance of mental health as a key mediator for employment-related outcomes. These data indicate that ART clients experience greater improvements compared to pre-ART clients, and not only with regard to general health, but also in restoring confidence in their ability to work, as well as actual work status.

BackgroundYoung people in the Middle East and North Africa (MENA) are profoundly affected by violence, high unemployment, and economic hardship. Experiences of community-level violence and personal trauma increase the likelihood that young people will engage in risky behaviors that include smoking, drug use, and unsafe sex. Little is known about the sexual behavior of young people in the region, particularly in the occupied Palestinian territory (oPt). Our aim in this study was to gain an insight into the perceived prevalence and patterns of sexual behavior among Palestinian youth.MethodsThe study was based on ten focus groups and 17 in-depth interviews with young people aged 16-24 years as part of the formative phase of a cross-sectional representative study of risk behaviors in the West Bank, including Jerusalem, in 2012. The sample was selected using a combination of purposive and convenience sampling. Qualitative analysis was used to code detailed notes of focus groups and interviews.ResultsBased on participants’ reports, different types of sexual activity outside marriage were not uncommon, even in conservative communities. The most reported sexual activity was non-penetrative sex: oral and anal intercourse, and virtual sex. Some young people had sexual intercourse with sex workers; they went to brothels in Israel and to brothels operating clandestinely in the West Bank, including East Jerusalem. Most respondents were of the opinion that young people did not usually use protection during sexual intercourse. Many reported that youth engage in different types of sexual activity outside marriage for several reasons: to challenge the culture, financial constraints and inability to marry, basic human need, personal pleasure, suppression, to kill boredom, and to prove manhood.ConclusionsIn contrast with the conservative social context of the occupied Palestinian territory (oPt), the findings suggest that sexual activities outside marriage may be more common than is currently assumed. Sexual behavior in the oPt is a concern because of the low awareness of the potential health consequences. The results draw attention to the need to incorporate sexual reproductive health into the national agenda and ensure that it is included in the programs of national institutions.
