Socioeconomic patterns in indoor environment in Denmark: cross-sectional studies from 2000 and 2021

ObjectivesTo examine changes and socioeconomic patterns in indicators of a poor indoor environment in 2000 and 2021. Study designCross-sectional data from the Danish Health and Morbidity Survey in 2000 and 2021. MethodsThe study included 27,068 participants. Indicators of indoor environment (annoyances from mould, temperature, draught, traffic and neighbour noise, and presence of water damage) were obtained from questionnaires (2021) and partly by interview (2000). Socioeconomic status included home ownership, educational level, and household income. The degree of social inequality in the indoor environment was estimated using the concentration index of inequality. ResultsThe prevalence of annoyances due to draught, temperature, and noise increased significantly from 2000 to 2021 (e.g., temperature 5.9%–25.1%, odds ratio (OR) 6.72, 95% confidence interval (CI) 6.12–7.38), whereas the prevalence of water damage decreased (17.7%–13.8%, OR 0.85, 95% CI 0.76–0.96). No difference was seen in annoyances due to mould (3.1% in 2000 and 2.5% in 2021, OR 0.90, 95% CI 0.69–1.17). Social inequality was present for thermal conditions, annoyances due to noise and presence of water damage when assessed by income but not by educational level. Conditions were more prevalent among individuals with low income in both 2000 and 2021. ConclusionsThe proportion of individuals reporting a poor indoor environment due to thermal conditions and noise increased in the period 2000–2021. Social inequality was observed in all indicators of a poor indoor environment for household income, whereas the inequality was less pronounced when assessed by educational level.

Women's attitudes towards intimate partner violence in Guyana: a population-based study

Intimate partner violence (IPV) against women is a global health issue and a breach of human rights. However, the literature lacks understanding of how socioeconomic and geographic disparities influence women's attitudes toward IPV in Guyana over time. This study aimed to assess trends in women's attitudes about IPV in Guyana. Data from three nationally representative surveys from 2009, 2014 to 2019 were analysed. The prevalence of women's attitudes about IPV was assessed, specifically in response to going out without telling their partners, neglecting their children, arguing with their partner, refusing sex with their partner, or burning food prepared for family meals. A series of stratified subgroup analyses were also completed. We assessed trends in IPV using the slope index of inequality (SII) and the concentration index of inequality (CIX). We used multilevel mixed-effects logistic regression to assess factors associated with women's attitudes justifying IPV. The prevalence of women's attitudes justifying IPV for any of the five reasons declined from 16.4% (95% CI: 15.1-17.8) in 2009 to 10.8% (95% CI: 9.7-12.0) in 2019. Marked geographic and socioeconomic inequalities were observed among subgroups. The SII for any of the five reasons decreased from-20.02 to-14.28, while the CIX remained constant over time. Key factors associated with women's attitudes about IPV were area of residence, sex of the household head, marital status, respondent's level of education, wealth index quintile, and the frequency of reading newspapers/magazines. From 2009 to 2019, Guyana was able to reduce women's attitudes justifying IPV against women by 34.1% and shortened subgroup inequalities. However, the prevalence remained high in 2019, with persisted inequalities among subgroups. Effective strategies, including the use of media to raise awareness, promotion of community-based approaches, and educational campaigns focusing on geographic and socioeconomic disparities, are essential for continuing to reduce the prevalence of IPV and associated inequalities. The study was funded in part by the National Institutes of Health, Fogarty International Center grant number D43TW012189.

Socioeconomic inequalities in reproductive, maternal, newborn and child health in Guyana: a time trends analysis

Background Guyana is among the countries committed to achieving the sustainable development goals. This research assessed the patterns of change in reproductive, maternal, newborn, and child health (RMNCH) in Guyana. Methods Four nationally representative surveys conducted from 2009 to 2019 were assessed. Temporal trends in RMNCH indicators were assessed at the national level, by place of residence, and by wealth index. The slope index and concentration index of inequality were calculated to assess trends in inequalities over time. The average absolute annual change (AAAC) of the indicators was calculated using a weighted variance regression. Results From 2006 to 2019, we observed an increase in the coverage of institutional delivery (from 82.6% to 97.7%), and exclusive breastfeeding (from 21.4% to 31.0%), among others. Likewise, antenatal care with four or more visits increased from 77.4% in 2009 to 84.7% in 2019. The opposite was observed for coverage of current contraceptive use (modern methods) (from 32.7% to 28.2%), family planning needed satisfied (from 49.6% to 43.8%), tetanus toxoid in pregnancy (from 31.7% to 8.2%) and full vaccination coverage (from 82.0% to 63.4%). Under-five stunting prevalence decreased from 18.0% to 9.2% and the under-five mortality rate from 40.4 to 29.3 per 1,000 live births. The gap between the poorest and richest women tended to decrease for seven out of the 16 intervention indicators, as well as for under-five stunting prevalence and under-five mortality rate. Institutional delivery was the best performer in increasing coverage and decreasing inequality over time, while immunization with measles was the worst performer. Conclusions Guyana has made great progress in improving its RMNCH indicators. However, the observed decline in the coverage of several RMNCH indicators can be seen as a warning sign to redouble efforts to achieve sustainable development goals, SDGs 1 and 2, by 2030 and to reduce inequalities by lagging no one behind.

Trends in, projections of, and inequalities in non-communicable disease management indicators in Vietnam 2010-2030 and progress toward universal health coverage: A Bayesian analysis at national and sub-national levels.

SummaryBackgroundMovement towards Universal Health Coverage (UHC) can improve health services, risk factor management, and inequality in non-communicable diseases (NCD); conversely, prioritizing and monitoring NCD management can support pathways to UHC in resource-limited settings. We aimed to estimate trends in NCD management indicators in Vietnam from 2010, and projections to 2030 at national and sub-national levels; compute the probability of reaching UHC targets; and measure inequalities in NCD management indicators at demographic, geographic, and socio-economic levels.MethodsWe included data of 37,595 households from four nationally representative surveys from 2010. We selected and estimated the coverage of NCD health service and risk management indicators nationally and by six sub-national groups. Using Bayesian models, we provided trends and projections and calculated the probability of reaching UHC targets of 80% coverage by 2030. We estimated multiple inequality indices including the relative index of inequality, slope index of inequality, and concentration index of inequality, and provided an assessment of improvement in inequalities over the study period.FindingsNationally, all indicators showed a low probability of achieving 2030 targets except sufficient use of fruit and vegetables (SUFV) and non-use of tobacco (NUT). We observed declining trends in national coverage of non-harmful use of alcohol (NHUA), sufficient physical activity (SPA), non-overweight (NOW), and treatment of diabetes (TOD). Except for SPA, no indicator showed the likelihood of achieving 2030 targets at any regional level. Our model suggested a non-achievement of 2030 targets for all indicators in any wealth quintile and educational level, except for SUFV and NUT. There were diversities in tendency and magnitude of inequalities with widening gaps between genders (SPA, TOD), ethnic groups (SUFV), urban-rural areas (TOH), wealth quintiles, and educational levels (TOD, NUT, NHUA).InterpretationOur study suggested slow progress in NCD management at the national level and among key sub-populations in Vietnam, together with existing and increasing inequalities between genders, ethnicities, geographic areas, and socioeconomic groups. We emphasised the necessity of continuously improving the healthcare system and facilities, distributing resources between geographic areas, and simultaneously integrating economic, education, and gender intervention and programs.FundingNone.

Fluoridation cessation and oral health equity: a 7-year post-cessation study of Grade 2 schoolchildren in Alberta, Canada

ObjectiveCommunity water fluoridation, because of its universal scope and passive mechanism of uptake, is one component of a multifaceted approach to promoting equity in dental health. The objective of this study was to examine social inequities in children’s dental health in the Canadian cities of Calgary (fluoridation cessation in 2011) and Edmonton (still fluoridated).MethodsWe analyzed data from surveys of population-based samples of Grade 2 (approx. age 7) children in Calgary in 2009/2010 (pre-cessation; n=557) and in both Calgary and Edmonton in 2013/2014 (Calgary, n=3230; Edmonton, n=2304) and 2018/2019 (Calgary, n=2649; Edmonton, n=2600) (post-cessation). We estimated associations between several socioeconomic indicators and dental caries indicators (i.e., dental caries experience [deft, DMFT] and untreated decay in two or more teeth [untreated decay]) using zero-inflated Poisson, binary logistic regression, and the concentration index of inequality. We compared those associations over time (between survey waves) and between cities at post-cessation.ResultsPersistent social inequities in deft and untreated decay were evident; for example, having no dental insurance was significantly associated with higher odds of untreated decay across city and survey wave. In most (but not all) cases, differences between cities and survey waves were consistent with an adverse effect of fluoridation cessation on dental health inequities. For example, the association between no dental insurance and higher odds of untreated decay in Calgary was greater in 2018/2019 (later post-cessation) than in 2009/2010 (pre-cessation; odds ratio [OR] for comparison of coefficients = 1.89 [1.36–2.63], p<0.001) and 2013/2014 (early post-cessation; OR for comparison of coefficients = 1.67 [1.22–2.28], p=0.001); that same association in 2018/2019 was greater in Calgary (fluoridation cessation) than in Edmonton (still fluoridated) (OR for comparison of coefficients = 1.44 [1.03–2.02], p=0.033).ConclusionSocial inequities in dental caries were present in both Calgary and Edmonton. Those inequities tended to be worse in Calgary where fluoridation was ceased. Our findings may be relevant to other settings where income inequality is high, dental services are costly, and dental public health infrastructure is limited.

Trends in, projections of, and inequalities in reproductive, maternal, newborn and child health service coverage in Vietnam 2000-2030: A Bayesian analysis at national and sub-national levels.

SummaryBackgroundTo assess the reproductive, maternal, newborn and child health (RMNCH) service coverage in Vietnam with trends in 2000−2014, projections and probability of achieving targets in 2030 at national and sub-national levels; and to analyze the socioeconomic, regional and urban-rural inequalities in RMNCH service indicators.MethodsWe used national population-based datasets of 44,624 households in Vietnam from 2000 to 2014. We applied Bayesian regression models to estimate the trends in and projections of RMNCH indicators and the probabilities of achieving the 2030 targets. Using the relative index, slope index, and concentration index of inequality, we examined the patterns and trends in RMNCH coverage inequality.FindingsWe projected that 9 out of 17 health service indicators (53%) would likely achieve the 2030 targets at the national level, including at least one and four ANC visits, BCG immunization, access to improved water and adequate sanitation, institutional delivery, skilled birth attendance, care-seeking for pneumonia, and ARI treatment. We observed very low coverages and zero chance of achieving the 2030 targets at national and sub-national levels in early initiation and exclusive breastfeeding, family planning needs satisfied, and oral rehydration therapy. The most deprived households living in rural areas and the Northwest, Northeast, North Central, Central Highlands, and Mekong River Delta regions would not reach the 80% immunization coverage of DPT3, Polio3, Measles and full immunization. We found socioeconomic, regional, and urban-rural inequalities in all RMNCH indicators in 2014 and no change in inequalities over 15 years in the lowest-coverage indicators.InterpretationVietnam has made substantial progress toward UHC. By improving the government's health system reform efforts, re-allocating resources focusing on people in the most impoverished rural regions, and restructuring and enhancing current health programs, Vietnam can achieve the UHC targets and other health-related SDGs.FundingThe authors did not receive any funds for conducting this study.

Widespread inequalities in smoking & smokeless tobacco consumption across wealth quintiles in States of India: Need for targeted interventions.

Background & objectives:India is a large country with each State having distinct social, cultural and economic characteristics. Tobacco epidemic is not uniform across the country. There are wide variations in tobacco consumption across age, sex, regions and socio-economic classes. This study was conducted to understand the wide inequalities in patterns of smoking and smokeless tobacco consumption across various States of India.Methods:Analysis was conducted on Global Adult Tobacco Survey, India (2009-2010) data. Prevalence of both forms of tobacco use and its association with socio-economic determinants was assessed across States and Union Territories of India. Wealth indices were calculated using socio-economic data of the survey. Concentration index of inequality and one way ANOVA assessed economic inequality in tobacco consumption and variation of tobacco consumption across quintiles. Multiple logistic regression was done for tobacco consumption and wealth index adjusting for age, sex, area, education and occupation.Results:Overall prevalence of smoking and smokeless tobacco consumption was 13.9 per cent (14.6, 13.3) and 25.8 per cent (26.6, 25.0), respectively. Prevalence of current smoking varied from 1.6 per cent (richest quintile in Odisha) to 42.2 per cent (poorest quintile in Meghalaya). Prevalence of current smokeless tobacco consumption varied from 1.7 per cent (richest quintile in Jammu and Kashmir) to 59.4 per cent (poorest quintile in Mizoram). Decreasing odds of tobacco consumption with increasing wealth was observed in most of the States. Reverse trend of tobacco consumption was observed in Nagaland. Significant difference in odds of smoking and smokeless tobacco consumption with wealth quintiles was observed. Concentration index of inequality was significant for smoking tobacco -0.7 (-0.62 to-0.78) and not significant for smokeless tobacco consumption -0.15 (0.01to-0.33)Interpretation & conclusions:The findings of our analysis indicate that tobacco control policy and public health interventions need to consider widespread socio-economic inequities in tobacco consumption across the States in India.

Desigualdades socioeconômicas na baixa estatura infantil: a experiência brasileira, 1974-2007

O artigo pretente avaliar tendências da prevalência e da distribuição social da baixa estatura infantil no Brasil para calcular o efeito da renda e de políticas de redistribuição de serviços básicos implementadas recentemente no país. A prevalência de baixa estatura (escore z de altura para a idade abaixo de -2, utilizando-se os Padrões de Crescimento Infantil da Organização Mundial da Saúde) em crianças menores de cinco anos foi calculada a partir de dados coletados durante pesquisas domiciliares de abrangência nacional realizadas no Brasil em 1974-1975 (n = 34.409), 1989 (n = 7.374), 1996 (n = 4.149) e 2006-07 (n = 4.414). As desigualdades socioeconômicas absoluta e relativa na baixa estatura foram medidas através do coeficiente angular de desigualdade e do índice de concentração de desigualdade, respectivamente. Durante um período de 33 anos, documentamos um declínio constante na prevalência nacional de baixa estatura, de 37,1% para 7,1%. A prevalência diminuiu de 59,0% para 11,2% no quinto mais pobre e de 12,1% para 3,3% no quinto mais rico. O declínio foi particularmente acentuado nos dez últimos anos do período (1996 a 2007), quando as diferenças entre as famílias pobres e ricas que possuíam crianças menores de cinco anos também diminuíram em termos de poder aquisitivo; acesso a educação, assistência médica e serviços de água e saneamento; e indicadores de saúde reprodutiva. No Brasil, o desenvolvimento socioeconômico, aliado a políticas públicas visando à igualdade, tem sido acompanhados por significativas melhorias das condições de vida e por um declínio substancial da desnutrição infantil, assim como por uma redução da diferença de estado nutricional entre crianças nos quintos socioeconômicos mais altos e mais baixos. Estudos futuros mostrarão se esses ganhos serão mantidos durante a atual crise econômica global.

Narrowing socioeconomic inequality in child stunting: the Brazilian experience, 1974–2007

To assess trends in the prevalence and social distribution of child stunting in Brazil to evaluate the effect of income and basic service redistribution policies implemented in that country in the recent past. The prevalence of stunting (height-for-age z score below -2 using the Child Growth Standards of the World Health Organization) among children aged less than 5 years was estimated from data collected during national household surveys carried out in Brazil in 1974-75 (n = 34,409), 1989 (n = 7374), 1996 (n = 4149) and 2006-07 (n = 4414). Absolute and relative socioeconomic inequality in stunting was measured by means of the slope index and the concentration index of inequality, respectively. Over a 33-year period, we documented a steady decline in the national prevalence of stunting from 37.1% to 7.1%. Prevalence dropped from 59.0% to 11.2% in the poorest quintile and from 12.1% to 3.3% among the wealthiest quintile. The decline was particularly steep in the last 10 years of the period (1996 to 2007), when the gaps between poor and wealthy families with children under 5 were also reduced in terms of purchasing power; access to education, health care and water and sanitation services; and reproductive health indicators. In Brazil, socioeconomic development coupled with equity-oriented public policies have been accompanied by marked improvements in living conditions and a substantial decline in child undernutrition, as well as a reduction of the gap in nutritional status between children in the highest and lowest socioeconomic quintiles. Future studies will show whether these gains will be maintained under the current global economic crisis.
