The silent epidemic of obesity in The Gambia: evidence from a nationwide, population-based, cross-sectional health examination survey.

OBJECTIVES: Non-communicable diseases account for 70% of global deaths; 80% occur in low-income and middle-income countries. The rapid increase of obesity in sub-Saharan Africa is a concern. We assessed generalised and abdominal obesity and their associated risk factors among adults in The Gambia. DESIGN: Nationwide cross-sectional health examination survey using the WHO STEPwise survey methods. SETTING: The Gambia. PARTICIPANTS: This study uses secondary analysis of a 2010 nationally representative random sample of adults aged 25-64 years (78% response rate). The target sample size was 5280, and 4111 responded. Analysis was restricted to non-pregnant participants with valid weight and height measurements (n=3533). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome variable was generalised obesity, using WHO body mass index (BMI) thresholds. Analyses used non-response weighting and adjusted for the complex survey design. We conducted multinomial logistic regression analysis to identify factors associated with BMI categories. The secondary outcome variable was abdominal obesity, defined as high waist circumference (using the International Diabetes Federation thresholds for Europeans). RESULTS: Two-fifths of adults were overweight/obese, with a higher obesity prevalence in women (17%, 95% CI 14.7 to 19.7; men 8%, 95% CI 6.0 to 11.0). 10% of men and 8% of women were underweight. Urban residence (adjusted relative risk ratio 5.8, 95% CI 2.4 to 14.5), higher education (2.3, 1.2 to 4.5), older age, ethnicity, and low fruit and vegetable intake (2.8, 1.1 to 6.8) were strongly associated with obesity among men. Urban residence (4.7, 2.7 to 8.2), higher education (2.6, 1.1 to 6.4), older age and ethnicity were associated with obesity in women. CONCLUSION: There is a high burden of overweight/obesity in The Gambia. While obesity rates in rural areas were lower than in urban areas, obesity prevalence was higher among rural residents in this study compared with previous findings. Preventive strategies should be directed at raising awareness, discouraging harmful beliefs on weight, and promoting healthy diets and physical activity.

HIV/AIDS knowledge, attitudes and behaviour of persons with and without disabilities from the Uganda Demographic and Health Survey 2011: Differential access to HIV/AIDS information and services.

Uganda is among the first to use the Washington Group Short Set of Questions on Disability to identify persons with disabilities in its Demographic and Health Survey. In this paper, we review the HIV Knowledge, Attitudes and Behaviour component of the 2011 Ugandan Demographic and Health Survey, analysing a series of questions comparing those with and without disabilities in relation to HIV/AIDS knowledge, attitudes and practices. We found comparable levels of knowledge on HIV/AIDS for those with and those without disabilities in relation to HIV transmission during delivery (93.89%, 93.26%) and through breastfeeding (89.91%, 90.63%), which may reflect increased attention to reaching the community of persons with disabilities. However, several gaps in the knowledge base of persons with disabilities stood out, including misconceptions of risk of HIV infection through mosquito bites and caring for a relative with HIV in own household (34.39%, 29.86%; p<0.001; 91.53%, 89.00%; p = 0.001, respectively). The issue is not just access to appropriate information but also equitable access to HIV/AIDS services and support. Here we found that persons with multiple disabilities were less likely than individuals without disabilities to return to receive results from their most recent HIV test (0.60[0.41-0.87], p<0.05). HIV testing means little if people do not return for follow-up to know their HIV status and, if necessary, to be connected to available services and supports. Additional findings of note were that persons with disabilities reported having a first sexual encounter at a slightly younger age than peers without disabilities; and persons with disabilities also reported having a sexually transmitted disease (STD) within the last 12 months at significantly higher rates than peers without disabilities (1.38[1.18-1.63], p<0.01), despite reporting comparable knowledge of the need for safer sex practices. This analysis is among the first to use HIV/AIDS-related questions from Demographic Health Surveys to provide information about persons with disabilities in Uganda in comparison to those without disabilities. These findings present a more complex and nuanced understanding of persons with disabilities and HIV/AIDS. If persons with disabilities are becoming sexually active earlier, are more likely to have an STD within the preceding 12 month period and are less likely to receive HIV test results, it is important to understand why. Recommendations are also made for the inclusion of disability measures in Uganda's AIDS Indicator Survey to provide cyclical and systematic data on disability and HIV/AIDS, including HIV prevalence amongst persons with disabilities.

Surviving polio in a post-polio world.

Excitement mounts as the global health and international development communities anticipate a polio-free world. Despite substantial political and logistical hurdles, only 223 cases of wild poliovirus in three countries were reported in 2012. Down 99% from the estimated 350,000 annual cases in 125 countries in 1988-this decline signals the imminent global eradication of polio. However, elimination of new polio cases should not also signal an end to worldwide engagement with polio. As many as 20 million continue to live with the disabling consequences of the disease. In developed countries where polio immunization became universal after dissemination of the polio vaccine in the 1950s, almost all individuals who have had polio are now above age 50. But in many developing countries where polio vaccination campaigns reached large segments of the population only after 1988, millions disabled by polio are still children or young adults. Demographically, this group is also different. After three decades of immunization efforts, those children unvaccinated in the late 1980s were more likely to be from poorer rural and slum communities and to be girls-groups not only harder to reach than more affluent members of the population but also individuals who, if they contract polio, are less likely to have access to medical and rehabilitation programs or education, job training, employment and social support services. The commitment to eradicate polio should not be considered complete while those living with the disabling sequelae of polio continue to live in poor health, poverty and social isolation. This paper reviews what is currently known about disabled survivors of polio and highlights areas of need in public health research, policy and programming. Based on a literature review, discussion and field observations, we identify continuing challenges posed by polio and argue that the attention, funding and commitment now being directed towards eradication be shifted to provide for the rehabilitative, medical, educational and social needs of those for whom the disabling sequelae of polio will remain a daily challenge for decades to come.

HIV issues and people with disabilities: a review and agenda for research.

The recent AIDS and Disability Partners Forum at the UN General Assembly High Level Meetings on AIDS in New York in June 2011 and the International AIDS Conference in Washington, DC in July 2012 underscores the growing attention to the impact of HIV and AIDS on persons with disabilities. However, research on AIDS and disability, particularly a solid evidence base upon which to build policy and programming remains thin, scattered and difficult to access. In this review paper, we summarise what is currently known about the intersection between HIV and AIDS and disability, paying particular attention to the small but emerging body of epidemiology data on the prevalence of HIV for people with disabilities, as well as the increasing understanding of HIV risk factors for people with disabilities. We find that the number of papers in the peer-reviewed literature remains distressingly small. Over the past 20 years an average of 5 articles on some aspect of disability and HIV and AIDS were published annually in the peer-reviewed literature from 1990 to 2000, increasing slightly to an average of 6 per year from 2000 to 2010. Given the vast amount of research around HIV and AIDS and the thousands of articles on the subject published in the peer-reviewed literature annually, the continuing lack of attention to HIV and AIDS among this at risk population, now estimated to make up 15% of the world's population, is striking. However, the statistics, while too limited at this point to make definitive conclusions, increasingly suggest at least an equal HIV prevalence rate for people with disabilities as for their non-disabled peers.

The intersection of everyday life and group prenatal care for women in two urban clinics.

Women from vulnerable populations encounter challenging circumstances that generate stress and may adversely affect their health. Group prenatal care (GPNC) incorporates features that address social stressors, and has been demonstrated to improve pregnancy outcomes and prenatal care experiences. In this qualitative study, we describe the complex circumstances in the lives of women receiving care in two urban clinics and how GPNC attenuated them. Stressors included problems with transportation and child care, demanding jobs, poverty, homelessness, difficult relationships with partners, limited family support, and frustrating health care experiences. Receiving prenatal care in groups allowed women to strengthen relationships with significant others, gain social support, and develop meaningful relationships with group leaders. By eliminating waits and providing the opportunity to participate in care, GPNC also offered sanctuary from frustrations encountered in receiving individual care. Reducing such stressors may help improve pregnancy outcomes; however, more evidence is needed on mechanisms underlying these effects.

Surviving sepsis in low-income and middle-income countries: new directions for care and research.

Sepsis is a disorder characterised by systemic inflammation secondary to infection. Despite recent progress in the understanding and treatment of sepsis, no data or recommendations exist that detail effective approaches to sepsis care in resource-limited low-income and middle-income countries (LMICs). Although few data exist on the burden of sepsis in LMICs, the prevalence of HIV and other comorbid conditions in some LMICs suggest that sepsis is a substantial contributor to mortality in these regions. In well-resourced countries, sepsis management relies on protocols and complex invasive technologies not widely available in most LMICs. However, the key concepts and components of sepsis management are potentially translatable to resource-limited environments. Health personnel in LMICs should be educated in the recognition of sepsis and the importance of early and appropriate antibiotic use. Simple and low-cost standardised laboratory testing should be emphasised to allow accurate diagnosis, prognosis, and monitoring of treatment response. Evidence-based interventions and treatment algorithms tailored to LMIC ecology and resources should thus be developed and validated.

Immunization rates among disabled children in Ecuador: unanticipated findings.

Researchers hypothesize that impoverished parents in developing countries may forego provision of healthcare for disabled children, instead allocating scarce resources to nondisabled children or other household needs. We compared the immunization rates of 32 children with complex special heathcare needs with those of 95 nondisabled siblings in coastal Ecuador. Almost 100% (31 of 32) of the disabled children studied were immunized at a rate comparable with their nondisabled siblings. We propose that this finding is attributable to an effective national immunization program and to positive local sociocultural attitudes toward disability. These findings underscore the need for more research on disability across cultures.

Cultural influences on health care use: differences in perceived unmet needs and expectations of providers by Latino and Euro-American parents of children with special health care needs.

This study compares service use, perceived unmet needs, and expectations of providers of Latino and Euro-American families of children with disabilities enrolled in a Title V Program. Eighty-four families and 20 providers participated in open-ended, semistructured, and structured interviews. Latino families underused Title V services (p <.001). The Latino families were more likely to cite unmet needs in the following areas: an unresolved health problem (p <.05), rehabilitation therapy programs (p <.001), or need for more information or a support group (p <.001). The Euro-American families cited unmet needs in the following areas: lack of day care (p <.001), respite services (p <.001), recreational programs (p <.001), and home health aides (p <.007). Textual analysis of open interviews revealed that the two groups of families had different expectations of providers. Latino cultural values play a role in these differences, creating barriers for effectively communicating with providers and for meeting children's needs.
