This study aimed to (a) assess the relationship between a person's occupational category and their physical inactivity, and (b) analyze the association among country-level variables and physical inactivity. The World Health Survey (WHS) was administered in 2002-2003 among 47 low- and middle-income countries (n = 196,742). The International Physical Activity Questionnaire (IPAQ) was used to collect verbal reports of physical activity and convert responses into measures of physical inactivity. Eco ...[more]

Project description:ObjectivesPhysical inactivity is a risk factor for premature mortality and several non-communicable diseases. The purpose of this study was to estimate the global burden associated with physical inactivity, and to examine differences by country income and region.MethodsPopulation-level, prevalence-based population attributable risks (PAR) were calculated for 168 countries to estimate how much disease could be averted if physical inactivity were eliminated. We calculated PARs (percentage of cases attributable to inactivity) for all-cause mortality, cardiovascular disease mortality and non-communicable diseases including coronary heart disease, stroke, hypertension, type 2 diabetes, dementia, depression and cancers of the bladder, breast, colon, endometrium, oesophagus, stomach and kidney.ResultsGlobally, 7.2% and 7.6% of all-cause and cardiovascular disease deaths, respectively, are attributable to physical inactivity. The proportions of non-communicable diseases attributable to physical inactivity range from 1.6% for hypertension to 8.1% for dementia. There was an increasing gradient across income groups; PARs were more than double in high-income compared with low-income countries. However, 69% of total deaths and 74% of cardiovascular disease deaths associated with physical inactivity are occurring in middle-income countries, given their population size. Regional differences were also observed, with the PARs occurring in Latin America/Caribbean and high-income Western and Asia-Pacific countries, and the lowest burden occurring in Oceania and East/Southeast Asia.ConclusionThe global burden associated with physical inactivity is substantial. The relative burden is greatest in high-income countries; however, the greatest number of people (absolute burden) affected by physical inactivity are living in middle-income countries given the size of their populations.

Project description:OBJECTIVE:Using estimates from the Global Burden of Disease (GBD) study, we examined differences in unintentional occupational injury mortality rates from 1990 to 2016 between high-income countries (HICs) and low- and middle-income countries (LMICs). METHODS:Unintentional occupational injury mortality rates were obtained through the GBD online visualization tool. We quantified mortality changes over time for common external causes of injury for ages 15?49 years and 50?69 years separately in HICs and LMICs using negative binomial regression models. RESULTS:In 2016, there were 24,396 and 303,999 unintentional occupational injury deaths among individuals aged 15 to 69 years in HICs and LMICs, respectively, corresponding to 3.1 and 7.0 per 100,000 people. Between 1990 and 2016, unintentional occupational injury mortality for people aged 15?69 years dropped 46% (from 5.7 to 3.1 per 100,000 people) in HICs and 42% in LMICs (from 13.2 to 7.0 per 100,000 people). Sustained and large disparities existed between HICs and LMICs for both sexes and both age groups during 1990?2016 (mortality rate ratio: 2.2?2.4). All unintentional occupational injury causes of death displayed significant reduction with one exception (ages 15?49 years in HICs). Country-specific analysis revealed large variations in unintentional occupational injury mortality and changes in occupational injury mortality between 1990 and 2016. CONCLUSIONS:Despite substantial decreases in mortality between 1990 and 2016 for both HICs and LMICs, a large disparity continues to exist between HICs and LMICs. Multifaceted efforts are needed to reduce the disparity.

Project description:BackgroundPromotion of physical activity (PA) among populations is a global health investment. However, evidence on economic aspects of PA is sparse and scattered in low-income and middle-income countries (LMICs).ObjectiveThe objective of this study was to summarise the available evidence on economics of PA in LMICs, identify potential target variables for policy and report gaps in the existing economic evidence alongside research recommendations.Data sourcesA systematic review of the electronic databases (Scopus, Web of Science and SPORTDiscus) and grey literature.Study eligibility criteriaCost-of-illness studies, economic evaluations, interventions and descriptive studies on economic factors associated with PA using preset eligibility criteria.Study appraisal and synthesis of methodsScreening, study selection and quality appraisal based on standard checklists performed by two reviewers with consensus of a third reviewer. Descriptive synthesis of data was performed.ResultsThe majority of the studies were from upper-middle-income countries (n=16, 88.8%) and mainly from Brazil (n=9, 50%). Only one economic evaluation study was found. The focus of the reviewed literature spanned the economic burden of physical inactivity (n=4, 22%), relationship between PA and costs (n=6, 46%) and socioeconomic determinants of PA (n=7, 39%). The findings showed a considerable economic burden due to insufficient PA, with LMICs accounting for 75% of disability-adjusted life years (DALYs) globally due to insufficient PA. Socioeconomic correlates of PA were identified, and inverse relationship of PA with the cost of chronic diseases was established. Regular PA along with drug treatment as a treatment scheme for chronic diseases showed advantages with a cost-utility ratio of US$3.21/quality-adjusted life year (QALY) compared with the drug treatment-only group (US$3.92/QALY) by the only economic evaluation conducted in the LMIC, Brazil.LimitationsMeta-analysis was not performed due to heterogeneity of the studies.Conclusions and recommendationsEconomic evaluation studies for PA promotion interventions/strategies and local research from low-income countries are grossly inadequate. Setting economic research agenda in LMICs ought to be prioritised in those areas.Prospero registration numberCRD42018099856.

Project description:BACKGROUND:The health of the caregivers is crucial to sustain informal care provision, while multimorbidity is an important health risk concept. However, studies on the association between informal caregiving and physical multimorbidity are currently lacking. Therefore, we investigated this association in adults from 48 low- and middle-income countries (LMICs). METHOD:Cross-sectional data from 242,952 adults (mean age 38.4 years) participating in the World Health Survey 2002-2004 were analyzed. Informal caregivers were considered those who provided help in the past year to a relative or friend (adult or child) who has a long-term physical or mental illness or disability, or is getting old and weak. Nine physical conditions were assessed. Multivariable logistic regression analyses were conducted to assess associations between informal caregiving and physical multimorbidity, while the between-country heterogeneity in this relationship was studied with country-wise analyses. RESULTS:The overall prevalence of informal caregiving and physical multimorbidity (ie, two or more physical conditions) was 19.2% and 13.2%, respectively. Overall, caregivers had 1.40 (95% confidence interval = 1.29-1.52) times higher odds for physical multimorbidity. This association was particularly pronounced in younger caregivers (eg, 18-44 years: odds ratio = 1.54; 95% confidence interval = 1.37-1.72), whereas this association was not statistically significant among those aged ?65 and older (odds ratio = 1.19; 95% confidence interval = 0.98-1.44). Country-wise analyses corroborated these findings, and there was a negligible level of between-country heterogeneity (I2 = 24.0%). CONCLUSIONS:In LMICs, informal caregivers (especially young caregivers) were more likely to have physical multimorbidity. This should be taken into account in policies that address the health and well-being of informal caregivers.

Project description:BackgroundGrowth and early development (ECD) are vital outcomes for children. This study aimed to examine the association between child growth and overall development in children aged 3 to 5?years in low- and middle-income countries.MethodsA secondary analysis of nationally representative data collected in UNICEF's Multiple Indicator Cluster Surveys (MICS) and national Demographic and Health Surveys (DHS). The early development of children aged 3 to 5?years from the randomly selected households was ascertained using a 10-item scale which assessed four developmental domains: language-cognitive, physical, socio-emotional, and approaches to learning with a total development score ranging from 0 (the least optimal) to 10 (the most optimal). Children's growth, the height-for-age Z score (HAZ), was calculated using the WHO Child Growth Standards. Unadjusted (Pearson's correlation coefficient, r) and adjusted estimations (standardised mean difference (SMD) adjusted for child sex, child age, and household wealth index) of the magnitude of the association between HAZ and ECD scores were calculated for each country.ResultsData contributed by 178,393 children aged 36 to 59?months from 55 countries were included in the analyses. The pooled r between HAZ and standardised ECD scores was 0.12 and the pooled adjusted SMD was 0.06. The r ranged from ~?0 in Barbados, Lebanon, and Moldova to 0.32 in Pakistan and 0.36 in Nigeria. Overall, 47/55 countries had correlation coefficients less than the cut-off for a small association. The adjusted SMDs were ~?0 in 20 countries. All SMDs were lower than the cut-off for a small effect size. The magnitudes of the association were highest in South Asia and lowest in Middle East and North Africa, and lowest in the highest HDI group.ConclusionsThe association between growth and development in early childhood appears to be primarily a co-occurrence because the magnitude of the association varies among settings from no association in higher-income countries to a moderate level in low-income countries. In low-income countries, interventions targeting child growth and ECD should be integrated given their common risks frequency in these settings. Overall, growth is not a sensitive and therefore suitable indicator of child development.

Project description:In recent decades low- and middle-income countries (LMICs) have been witnessing a significant shift toward raised blood pressure; yet in LMICs, only 1 in 3 are aware of their hypertension status, and ≈8% have their blood pressure controlled. This rising burden widens the inequality gap, contributes to massive economic hardships of patients and carers, and increases costs to the health system, facing challenges such as low physician-to-patient ratios and lack of access to medicines. Established risk factors include unhealthy diet (high salt and low fruit and vegetable intake), physical inactivity, tobacco and alcohol use, and obesity. Emerging risk factors include pollution (air, water, noise, and light), urbanization, and a loss of green space. Risk factors that require further in-depth research are low birth weight and social and commercial determinants of health. Global actions include the HEARTS technical package and the push for universal health care. Promising research efforts highlight that successful interventions are feasible in LMICs. These include creation of health-promoting environments by introducing salt-reduction policies and sugar and alcohol tax; implementing cost-effective screening and simplified treatment protocols to mitigate treatment inertia; pooled procurement of low-cost single-pill combination therapy to improve adherence; increasing access to telehealth and mHealth (mobile health); and training health care staff, including community health workers, to strengthen team-based care. As the blood pressure trajectory continues creeping upward in LMICs, contextual research on effective, safe, and cost-effective interventions is urgent. New emergent risk factors require novel solutions. Lowering blood pressure in LMICs requires urgent global political and scientific priority and action.

Project description:IntroductionEvidence on the economic costs of physical inactivity and the cost-effectiveness of physical activity interventions in low-income and middle-income countries (LMICs) is sparse, and fragmented where they are available. This is the first review aimed to summarise available evidence on economics of physical activity in LMICs, identify potential target variables for policy, and identify and report gaps in the current knowledge on economics of physical activity in LMICs.Methods and analysisPeer-reviewed journal articles of observational, experimental, quasi-experimental and mixed-method studies on economics of physical activity in LMICs will be identified by a search of electronic databases; Scopus, Web of Science and SPORTDiscus. Websites of WHO, the National Institute for Health and Care Excellence international, World Bank and reference lists of included studies will be searched for relevant studies. The study selection process will be a two-stage approach; title and abstract screen for inclusion, followed by a review of selected full-text articles by two independent reviewers. Disagreements will be resolved by consensus and discussion with a third reviewer. Data will be extracted using standardised piloted data extraction forms. Risk of bias will be critically appraised using standard checklists based on study designs. Descriptive synthesis of data is planned. Where relevant, summaries of studies will be classified according to type of economic analysis, country or country category, population, intervention, comparator, outcome and study design. Meta-analysis will be performed where appropriate. This protocol for systematic review is prepared according to the Preferred Reporting Items for Systematic review and Meta-analysis for Protocols -2015 statement.Ethics and disseminationEthical approval is not obtained as original data will not be collected as part of this review. The completed review will be submitted for publication in a peer-reviewed journal and presented at conferences.Prospero registration numberCRD42018099856.

Project description:BackgroundAnemia remains a major public health issue, particularly for children and women in low- and middle-income countries (LMICs). However, the current prevalence and recent changes of anemia among young children and women of reproductive age, particularly for pregnant women in different trimesters are unclear. We examined the current prevalence of anemia among children aged less than 5 years by age (6-35 months vs. 36-59 months) and women of reproductive age by pregnant status (pregnant vs. non-pregnant) and trimesters (the third vs. the second vs. the first trimester) between 2010 and 2018 and further examined changes in the prevalence from 2000-2009 to 2010-2018.MethodsData were from the cross-sectional Demographic and Health Surveys performed between 2000 and 2018. A total of 47 countries were included to examine the current prevalence of anemia (weighted prevalence and 95% confidence interval [CI]) among young children aged less than 5 years (N = 459,785) and 46 countries among women of reproductive age (N = 1,079,805) between 2010 and 2018. To examine changes in the prevalence of anemia, a total of 29 countries with at least two Demographic and Health Surveys performed between 2000 and 2009 (children: N = 130,772; women: N = 371,845) and 2010-2018 (children: N = 386,202; women: N = 928,889) were included. Modified Poisson regression analyses with robust error variance were used to examine changes in anemia between 2000-2009 and 2010-2018 in participants by child age (6-5 months vs. 36-59 months), women pregnant status (pregnant vs. non-pregnant), trimesters (the second or third trimester vs. the first trimester) with the adjustment for potential covariates.FindingsIn 47 LMICs for children aged less than 5 years between 2010 and 2018, the total prevalence of anemia was 56.5% (95% CI 56.2, 56.8). Younger children aged 6-35 months were more likely to have anemia than older children aged 36-59 months (adjusted odds ratio [OR] 1.38, 95% CI 1.36-1.39, P < 0.001). In 46 LMICs for women of reproductive age, the total prevalence was 40.4% (95% CI 40.1, 40.7). Pregnant women were more likely to have anemia than non-pregnant women (adjusted OR 1.14, 1.12-1.16, P < 0.001). Moreover, pregnant women in the third trimester (adjusted OR 1.55, 1.48-1.62, P < 0.001) and the second trimester (adjusted OR 1.51, 1.45-1.58, P < 0.001) were more likely to have anemia than those in the first trimester. Among 29 included countries, although there was a decreasing change (absolute change, relative change, and average annual rate of reduction) in young children and women between 2000-2009 and 2010-2018 in a majority of countries, the current prevalence of anemia remained at a high level.InterpretationThe prevalence of anemia among children aged less than 5 years and women of reproductive age was still high in LMICs, particularly for younger children and pregnant women. The relative change among women of reproductive age was far away from the WHO goal of reduction of anemia by 50% by 2025 (i.e., prevalence reduction to about 15.2% by 2025 from 30.3% at 2012 baseline). Continued and effective efforts, particularly for high-risk populations, are needed to improve the general health of the population.FundingInnovation Team of "Climbing" Program of Shandong University, and the Youth Team of Humanistic and Social Science of Shandong University (20820IFYT1902).

Project description:INTRODUCTION:Physical activity (PA) is a beneficial health behaviour, however most adolescents worldwide are physically inactive. Updated information on the prevalence and trends of PA is important to inform national and international authorities and support countries' public health policies and actions. This study aimed to present the worldwide, regional, and national prevalence of PA participation according to its frequency in adolescents. METHODS:This study is based on cross-sectional surveys of adolescents' populations from several countries and all regions worldwide. The sample comprised 520,533 adolescents (251,788 boys; 268,745 girls), from 105 countries and regions. RESULTS:Most adolescents engaged in PA up to 3 days/week (57.1%; 95% CI: 56.9; 57.2). The prevalence of engaging in PA every day decreases over the age from 28.2% at age of 11-12 years (95% CI: 27.4; 29.0) to 21.2% at age of 16-17 years (95% CI: 20.3; 22.0) among boys; and from 19.4% (95% CI: 18.5; 20.2) to 11.1% (95% CI: 10.1; 12.0) among girls. For boys and girls who engaged in PA 5-6 days/week, the prevalence increases from countries with the lowest human development index to countries with the highest. Cambodia (7.3%, 95% CI: 3.8; 10.8), Philippines (7.7%, 95% CI: 5.6; 9.7), Sudan (8.8%, 95% CI: 4.7; 12.9), Timor-Leste (8.9%, 95% CI: 5.5; 12.3), and Afghanistan (10.1%, 95% CI: 6.1; 14.1) were the countries with the lowest prevalence of sufficient PA. CONCLUSIONS:National, regional, and worldwide data on the prevalence of physical activity in adolescents highlights the importance of improving the global levels of PA, especially in girls. Identifying the factors causing the age-related decrease in physical activity levels will permit public health entities to define priority actions and policies against physical inactivity.

Project description:ObjectivesTo assess the association between chronic physical conditions and multimorbidity and mild cognitive impairment (MCI) in low- and middle-income countries (LMICs).DesignNationally representative, cross-sectional, community-based study.SettingSix countries that participated in the World Health Organization Study on Global Ageing and Adult Health.ParticipantsIndividuals aged 50 and older (N=32,715; mean age 62.1 ± 15.6; 51.7% female).MeasurementsThe definition of MCI was based on the recommendations of the National Institute on Ageing and Alzheimer's Association. Ten chronic conditions were assessed (angina pectoris, arthritis, asthma, cataract, chronic lung disease, diabetes mellitus, edentulism, hearing problems, hypertension, stroke). Multivariable logistic regression analysis was conducted to assess the association between chronic physical conditions, multimorbidity (≥2 chronic conditions), and MCI.ResultsThe prevalence of multimorbidity was 49.8% (95% confidence interval (CI)=48.1-51.5%) and of MCI was 15.3% (95% CI=14.4-16.3%). After adjustment for potential confounders, edentulism (odds ratio (OR)=1.24), arthritis (OR=1.24), chronic lung disease (OR=1.29), cataract (OR=1.33), stroke (OR=1.94), hearing problems (OR=2.27), and multimorbidity (OR=1.40) were significantly associated with MCI. There was a gradual increase in the likelihood of MCI (1 condition: OR=1.21, 95% CI=1.03-1.42; ≥4 conditions: OR=2.07, 95% CI=1.70-2.52).ConclusionThese results highlight the need to investigate the underlying mechanisms linking chronic conditions and MCI and whether prevention or treatment of chronic conditions or multimorbidity can reduce the onset of cognitive decline and subsequent dementia, especially in LMICs.
