Blood pressure screening in Mozambique: the May Measurement Month 2017 project-Sub-Saharan Africa.

Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. In Mozambique, two national surveys of risk factors for chronic diseases were done, using the WHO STEPWISE approach, the first in 2005 and the last in 2014/2015. In this period of 10 years, the prevalence of hypertension in the adult population increased from 33.1% to 38.9% and the extremely low levels of awareness, treatment, and control did not change significantly. May Measurement Month (MMM) is a global initiative of the International Society of Hypertension aimed at raising awareness of high BP and to act as a temporary solution to the lack of screening programmes worldwide. An opportunistic cross-sectional survey of volunteers aged ≥18 years was carried out in May 2017. Blood pressure measurement, the definition of hypertension and statistical analysis followed the standard MMM protocol. Screening was conducted by volunteers, mainly in work places, markets, and religious activities, in the capital city, in most of the provincial capitals and some rural districts. About 4454 individuals were screened with a mean age of 39 years, and, after multiple imputation, 1371 (31.1%) had hypertension. Of individuals not receiving anti-hypertensive medication, 1099 (26.6%) were hypertensive. Of individuals receiving antihypertensive medication, 166 (61.6%) had uncontrolled BP. MMM17 was the largest BP screening campaign undertaken in Mozambique. These results suggest that opportunistic screening is an important tool to identify significant numbers of patients with raised BP.

HIV prevalence and incidence in a cohort of women at higher risk for HIV acquisition in Chókwè, southern Mozambique.

BACKGROUND: Reliable HIV incidence estimates for Mozambique are limited. We conducted a prospective HIV incidence study as part of a clinical research site development initiative in Chókwè district, Gaza Province, southern Mozambique. METHODS: Between June 2010 and October 2012, we recruited women at sites where women at higher risk of HIV infection would likely be found. We enrolled and tested 1,429 sexually active women in the screening phase and 479 uninfected women in the prospective phase. Participants were scheduled for 12+ months follow-up, when they underwent face-to-face interviews, HIV counseling and testing, and pregnancy testing. We observed a total of 373.1 woman-years (WY) of follow-up, with mean (median) of 9.4 (9.7) women-months per participant. RESULTS: The prevalence of HIV was 29.4% (95% confidence interval [CI]: 27.0-31.8%). In multivariable logistic regression analysis, factors that remained significantly associated with prevalent HIV were: older age (OR: 0.6; 95% CI: 0.4-0.7), lower educational level (OR: 0.4; 95% CI: 0.3-0.7), and using hormonal contraception (OR: 0.6; 95% CI: 0.4-0.7) or condoms (OR: 0.5; 95% CI: 0.3-0.7). We observed an HIV incidence rate of 4.6 per 100 WY (95% CI: 2.7, 7.3). The HIV incidence was 4.8 per 100 WY (95% CI: 2.5, 8.3) in women aged 18-24 years, 4.5 per 100 WY (95% CI: 1.2, 11.4) in women aged 25-29 years and 3.2 per 100 WY (95% CI: 0.1, 18.0) in the 30-35 years stratum. None of the demographic factors or time-varying behavioral factors examined was significantly associated with incident HIV infection in bivariable analysis at p ≤ 0.10. CONCLUSIONS: We found a high HIV incidence among sexually active young women in Chókwè, Mozambique. HIV prevention programs should be strengthened in the area, with more comprehensive reproductive health services, regular HIV testing, condom promotion, and messaging about multiple sexual partners.
