Prevalence and associated factors of cardiovascular diseases among men and women aged 45 years and above: Analysis of the longitudinal ageing study in India, 2017-2019.

OBJECTIVE: Epidemiological studies on the prevalence and associated factors of cardiovascular diseases (CVDs) representative of all states of India among middle-aged and elderly are not much reported. The present study estimates the prevalence and associated factors of cardiovascular diseases across Indian states among men and women aged ≥45 years. METHODS: We used data from the Longitudinal Ageing Study in India wave 1 (2017-2019), which included a final analytical sample size of 56,935 adults and their spouses aged 45 years and above. We estimated CVDs prevalence for sociodemographic and behavioural variables, and multivariable logistic regression was used to assess the association between behavioural factors and CVDs in both men and women. RESULTS: The prevalence of CVDs was 5.2% among adults ≥45 years (women: 4.6%; men: 5.9%), hypertension was 46.7% (women:48.9%; men:44%). Men and women have a similar prevalence of diabetes (11.9%) and cholesterol (2.3%). Prevalence of physical inactivity was 30.3% (women:27%; men:34.1%). Hypertension (adjusted odds ratio; aOR women:2.60, 95% CI: 2.08-3.25, men:1.88, 95% CI 1.54-2.29), hypercholesterolemia (aOR women:1.70; 95% CI 1.07-2.69, men 3.55; 95% CI 2.66-4.74), diabetes (aOR women:2.53; 95% CI 1.83-3.51, men:1.77 95% CI 1.44-2.17), obesity, physical inactivity, and smoking in men were significantly associated with CVDs. CONCLUSION: The prevalence of CVDs and lifestyle risk factors among middle-aged and elderly poses severe concerns regarding noncommunicable disease (NCD) healthcare services provided in a lower-middle-income country like India. The key to preventing CVDs is controlling hypertension, diabetes, hypercholesterolemia, and increasing physical activity among adults aged ≥45 years.

Contraception and intersection with HIV services in 11 high HIV burden sub-Saharan African countries: Results from the population-based HIV Impact Assessment cross-sectional studies conducted from 2015 to 2018.

OBJECTIVE: The United Nations' Sustainable Development Goal 3.7.1 addresses the importance of family planning. The objective of this paper is to provide information on family planning to policymakers to help increase access to contraceptive methods to women in sub-Saharan Africa. METHODS: We analyzed data from the Population-based HIV Impact Assessment studies conducted in 11 sub-Saharan African countries from 2015 to 2018 to assess the relationship between HIV services and family planning. Analyses were restricted to women aged 15-49 years who reported being sexually active within the past 12 months and had data on contraceptive use. RESULTS: Approximately 46.4% of participants reported using any form of contraception; 93.6% of whom used modern contraceptives. Women with a positive HIV status were more likely to use contraceptives (P < 0.0001) than HIV-negative women. Unmet need was higher among women who were confirmed to be HIV-negative in Namibia, Uganda, and Zambia than confirmed to be positive. Women aged 15-19 years used contraception less than 40% of the time. CONCLUSION: This analysis highlights crucial gaps in progress among HIV-negative and young women (aged 15-19 years). To provide access to modern contraception for all women, programs and governments need to focus on women who desire but do not have access to these family planning resources.

Population-Based HIV Impact Assessments Survey Methods, Response, and Quality in Zimbabwe, Malawi, and Zambia.

BACKGROUND: The population-based HIV impact assessment (population-based HIV impact assessments) surveys are among the first to estimate national adult HIV incidence, subnational prevalence of viral load suppression, and pediatric HIV prevalence. We summarize the survey methods implemented in Zimbabwe, Malawi, and Zambia, as well as response rates and quality metrics. METHODS: Each cross-sectional, household-based survey used a 2-stage cluster design. Survey preparations included sample design, questionnaire development, tablet programming for informed consent and data collection, community mobilization, establishing a network of satellite laboratories, and fieldworker training. Interviewers collected demographic, behavioral, and clinical information using tablets. Blood was collected for home-based HIV testing and counseling (HBTC) and point-of-care CD4+ T-cell enumeration with results immediately returned. HIV-positive blood samples underwent laboratory-based confirmatory testing, HIV incidence testing, RNA polymerase chain reaction (viral load), DNA polymerase chain reaction (early infant diagnosis), and serum antiretroviral drug detection. Data were weighted for survey design, and chi square automatic interaction detection-based methods were used to adjust for nonresponse. RESULTS: Each survey recruited a nationally representative, household-based sample of children and adults over a 6-10-month period in 2015 and 2016. Most (84%-90%) of the 12,000-14,000 eligible households in each country participated in the survey, with 77%-81% of eligible adults completing an interview and providing blood for HIV testing. Among eligible children, 59%-73% completed HIV testing. Across the 3 surveys, 97.8% of interview data were complete and had no errors. CONCLUSION: Conducting a national population-based HIV impact assessment with immediate return of HIV and other point-of-care test results was feasible, and data quality was high.
