Monitoring breastfeeding indicators in high-income countries: Levels, trends and challenges.

ABSTRACT: Monitoring indicators of breastfeeding practices is important to protect and evaluate the progress of breastfeeding promotion efforts. However, high-income countries lack standardized methodology to monitor their indicators. We aimed to update and summarize nationally representative annual estimates of breastfeeding indicators in high-income countries and to describe methodological issues pertaining to the data sources used. A review was conducted through population-based surveys with nationally representative samples or health reports from nationally representative administrative data of electronic surveys or medical records. Methodological aspects and rates of all breastfeeding indicators available were summarized by country. The median and annual growth of breastfeeding in percentage points within countries with time-series data were estimated. Data from 51 out of 82 high-income countries were identified. The data were obtained through surveys (n = 32) or administrative data (n = 19). Seventy-one percent of countries have updated their indicators since 2015. Ever breastfed was the indicator most frequently reported (n = 46), with a median of 91%. By 6 months of age, the median equals 18% for exclusive and 45% for any breastfeeding. At 12 months, the median of continued breastfeeding decreased to 29%. The annual growth rate for ever breastfed, exclusive and any breastfeeding at 6 months and continued at 12 months varied from 1.5 to -2.0, 3.5 to -3.1, 5.0 to -1.0 and 5.0 to -1.9, respectively, with positive changes for most countries. Stronger interventions are needed to promote breastfeeding in high-income countries as a whole, and investments are required to monitor trends with standardized methodologies.

Project description:BackgroundIn low- and middle-income countries (LMICs), low levels of formal maternal educational are positively associated with breastfeeding whereas the reverse is true among women with higher levels of formal education. As such, breastfeeding has helped to reduce health equity gaps between rich and poor children. Our paper examines trends in breastfeeding and formula consumption by maternal educational in LMICs over nearly two decades.MethodsWe used 319 nationally representative surveys from 81 countries. We used WHO definitions for breastfeeding indicators and categorized maternal education into three categories: none, primary, and secondary or higher. We grouped countries according to the World Bank income groups and UNICEF regions classifications. The trend analyses were performed through multilevel linear regression to obtain average absolute annual changes in percentage points.ResultsSignificant increases in prevalence were observed for early initiation and exclusive breastfeeding across all education categories, but more prominently in women with no formal education for early breastfeeding and in higher level educated women for exclusive breastfeeding. Small decreases in prevalence were seen mostly for women with no formal education for continued breastfeeding at 1 and 2 years. Among formula indicators, only formula consumption between 6 and 23 months decreased significantly over the period for women with primary education. Analysis by world regions demonstrated that gains in early and exclusive breastfeeding were almost universally distributed among education categories, except in the Middle East and North Africa where they decreased throughout education categories. Continued breastfeeding at 1 and 2 years increased in South Asia, Latin America and the Caribbean, and Eastern Europe and Central Asia for primary or higher education categories. Declines occurred for the group of no formal education in South Asia and nearly all education categories in the Middle East and North Africa with a decline steeper for continued breastfeeding at 2 years. With a few exceptions, the use of formula is higher among children of women at the highest education level in all regions.ConclusionsOver the course of our study, women with no formal education have worsening breastfeeding indicators compared to women with primary and secondary or higher education.

Project description:ObjectivePrior studies have reported inequitable global access to essential medicines for cardiovascular disease (CVD) prevention, especially statins. Here we examine recent trends and disparities in statin utilisation at the income group, regional and country levels.DesignEcological study. Pharmaceutical sales data were used to examine statin utilisation in high-income counties (HICs) and low/middle-income countries (LMICs) from 2015 to 2020. Population estimates were obtained from the Global Burden of Disease. Fixed-effects panel regression analysis was used to examine associations between statin utilisation and country-level factors.SettingGlobal, including 41 HICs and 50 LMICs.ParticipantsPopulation older than 40 years of age.Primary and secondary outcome measuresStatin utilisation was measured using defined daily doses (DDDs) per 1000 population ≥40 years per day (TPD).ResultsGlobally, statin utilisation increased 24.7% from 54.7 DDDs/TPD in 2015 to 68.3 DDDs/TPD in 2020. However, regional and income group disparities persisted during this period. In 2020, statin utilisation was more than six times higher in HICs than LMICs (192.4 vs 28.4 DDDs/TPD, p<0.01). Substantial disparities were also observed between LMICs, ranging from 3.1 DDDs/TPD in West African nations to 225.0 DDDs/TPD in Lebanon in 2020. While statin utilisation increased in most LMICs between 2015 and 2020, several experienced declines in utilisation, most notably Venezuela (-85.1%, from 92.3 to 14.0 DDDs/TPD). In LMICs, every $100 increase in per capita health spending was associated with a 17% increase in statin utilisation, while every 10% increase in out-of-pocket health spending was associated with a 11% decline (both p<0.05).ConclusionsDespite global increases in statin utilisation, there are substantial regional and country-level disparities between HICs and LMICs. To address global CVD disparities, policymakers should promote increased and equitable access to statins in LMICs.
