Recovery and long-term health outcomes of Sars-CoV-2 infection in a prospective cohort in an urban setting, Kenya
Background Evidence on long COVID remains limited in sub-Saharan countries.Objective This study explored the occurrence of COVID-19-related symptoms and factors affecting recovery and long COVID severity in Nairobi, Kenya.Methods A prospective cohort of individuals testing positive for SARS-CoV-2 between February 2022 and February 2023 was followed until June 2023. COVID-19-related symptoms were assessed every three months. Time to recovery was a…
Worldwide trends in underweight and obesity from 1990 to 2022
BACKGROUND: Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. METHODS: ). For school-aged children and adolescents, we report thinness (BMI 2 SD above the median). FINDINGS: From 1990 to 20…
Drivers of informal sector and non-prescription medication use in pediatric populations in a low- and middle-income setting
Obtaining medication from the informal sector is common in low- and middle- income countries. Informal sector use increases the risk for inappropriate medication use, including inappropriate antibiotic usage. Infants are at the highest risk of complications from inappropriate medication use, yet there is insufficient knowledge about the risk factors driving caregivers to obtain medication from the informal sector for young children. We aimed to d…
Worldwide trends in hypertension prevalence and progress in treatment and control from 1990 to 2019
BACKGROUND: Hypertension can be detected at the primary health-care level and low-cost treatments can effectively control hypertension. We aimed to measure the prevalence of hypertension and progress in its detection, treatment, and control from 1990 to 2019 for 200 countries and territories. METHODS: We used data from 1990 to 2019 on people aged 30-79 years from population-representative studies with measurement of blood pressure and data on blo…
Using treatment guidelines to improve antibiotic use
Clinical practice guidelines have the potential to improve quality of care through improving decision making and antibiotic prescription. These guidelines are particularly important in areas with limited laboratory and specialist capacity.\n\nFor some of the common conditions managed in the hospitals, guidelines are not available or are outdated.\n\nTo reduce irrational antibiotic use and contain the threat of antimicrobial resistance, the proces…
Antimicrobial resistance control efforts in Africa
Background: Antimicrobial resistance (AMR) is a growing public health threat in Africa. AMR prevention and control requires coordination across multiple sectors of government and civil society partners.Objectives: To assess the current role, needs, and capacities of CSOs working in AMR in Africa.Methods: We conducted an online survey of 35 CSOs working in 37 countries across Africa. The survey asked about priorities for AMR, current AMR-specific …
Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries and territories
BACKGROUND: Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. METHODS: For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease …
Rising rural body-mass index is the main driver of the global obesity epidemic in adults
Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities 1,2 . This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity 3–6 . Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean B…
Evaluating hospital performance in antibiotic stewardship to guide action at national and local levels in a lower-middle income setting
BACKGROUND: Inappropriate use of antibiotics can lead to the development of resistant pathogens. Ensuring proper use of these important drugs in all healthcare facilities is essential. Unfortunately, however, very little is known about how antibiotics are used in LMIC clinical settings, nor to what degree antibiotic stewardship programmes are in place and effective. OBJECTIVE: We aimed to record all Antibiotic Stewardship policies and structures …
Worldwide trends in blood pressure from 1975 to 2015
BACKGROUND: Raised blood pressure is an important risk factor for cardiovascular diseases and chronic kidney disease. We estimated worldwide trends in mean systolic and mean diastolic blood pressure, and the prevalence of, and number of people with, raised blood pressure, defined as systolic blood pressure of 140 mm Hg or higher or diastolic blood pressure of 90 mm Hg or higher. METHODS: For this analysis, we pooled national, subnational, or comm…
Worldwide trends in body-mass index, underweight, overweight, and obesity from 1975 to 2016
BACKGROUND: Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults. METHODS: We pooled 2416 population-based studies with measurements of height…
The effect of health insurance and health facility-upgrades on hospital deliveries in rural Nigeria
BACKGROUND: Access to quality obstetric care is considered essential to reducing maternal and new-born mortality. We evaluated the effect of the introduction of a multifaceted voluntary health insurance programme on hospital deliveries in rural Nigeria. METHODS: We used an interrupted time-series design, including a control group. The intervention consisted of providing voluntary health insurance covering primary and secondary healthcare, includi…
Enablers and barriers for implementing high-quality hypertension care in a rural primary care setting in Nigeria
BACKGROUND: Hypertension is a highly prevalent risk factor for cardiovascular diseases in sub-Saharan Africa (SSA) that can be modified through timely and long-term treatment in primary care. OBJECTIVE: We explored perspectives of primary care staff and health insurance managers on enablers and barriers for implementing high-quality hypertension care, in the context of a community-based health insurance programme in rural Nigeria. DESIGN: Qualita…
Barriers to uptake of antenatal maternal screening tests in Senegal
In Senegal, recommended antenatal maternal screening tests are substantially underutilized. Efforts to increase test uptake should include accessible testing guidelines, reducing the cost of tests, raising awareness about the reasons for tests, and making the complete test set in point-of-care format accessible in peripheral health posts. National and international antenatal care policies and programs should facilitate access to maternal screenin…
Step-by-step guideline for disease-specific costing studies in low- and middle-income countries
BACKGROUND: Disease-specific costing studies can be used as input into cost-effectiveness analyses and provide important information for efficient resource allocation. However, limited data availability and limited expertise constrain such studies in low- and middle-income countries (LMICs). OBJECTIVE: To describe a step-by-step guideline for conducting disease-specific costing studies in LMICs where data availability is limited and to illustrate…
