Using extended concentration and achievement indices to study socioeconomic inequality in chronic childhood malnutrition: the case of Nigeria

Decomposing Education-Based Inequalities in Pre-Exposure Prophylaxis Knowledge for HIV Prevention Among Women in Cote d'Ivoire

Background

Antiretroviral chemoprophylaxis is a promising strategy for preventing the spread of human immunodeficiency virus (HIV). The knowledge of pre-exposure prophylaxis (PrEP) is required for intervention uptake and adherence to prevent the spread of HIV. This study aimed to decompose education-based inequalities in PrEP knowledge for HIV prevention among reproductive-aged women in Cote d'Ivoire.

Methods

A cross-sectional study design with a nationally representative sample of 12,934 women aged 15-49 years was analyzed from the 2021 Cote d'Ivoire Demographic and Health Survey. The survey was conducted between September to December, 2021. The outcome variable was the knowledge of PrEP for HIV prevention. Statistical analysis was conducted using percentage, concentration index, and Lorenz curve. The level of significance was set at p<0.05.

Results

A weighted prevalence of 14.5% (95% CI: 12.5-16.3%) was estimated for PrEP knowledge for HIV prevention. Overall, educated women had a higher knowledge of PrEP for HIV prevention (Conc. Index= 0.225; SE= 0.012; p<0.001). Across the levels of women's characteristics, the results showed higher PrEP knowledge for HIV prevention among educated women. Education (Contri: 40.7327%, Ec: 0.5390), exposure to internet (Contri: 20.1039%, Ec: 0.3484), place of residence (Contri: 12.9801%, Ec: -0.0537), household wealth (Contri: 10.0062%, Ec: 0.0642) and religion (Contri: 5.7509%, Ec: 0.0354) were positive contributors to PrEP knowledge for HIV prevention. On the other hand, age (Contri: -8.8298%, Ec: -0.0950) and region (Contri: -3.5942, Ec: -0.0768) were negative contributors to PrEP knowledge regarding HIV prevention among women of reproductive age in Cote d'Ivoire.

Conclusion

There is limited knowledge of PrEP for HIV prevention among women in Cote d'Ivoire. Educated women had greater knowledge of PrEP for HIV prevention. The results of this study could guide interventions targeted to enhance the knowledge of PrEP as an HIV prevention option.

Socioeconomic disparities in Rwanda's under-5 population's growth tracking and nutrition promotion: findings from the 2019-2020 demographic and health survey

BACKGROUND

Regular growth monitoring can be used to evaluate young children's nutritional and physical health. While adequate evaluation of the scope and quality of nutrition interventions is necessary to increase their effectiveness, there is little research on growth monitoring coverage measurement. The purpose of this study was to investigate socioeconomic disparities in under-5 Rwandan children who participate in growth monitoring and nutrition promotion.

METHODS

We used data from the 2019-2020 Rwanda Demographic and Health Survey (RDHS), which included 8092under-5 children. Percentage was employed in univariate analysis. To examine the socioeconomic inequalities, concentration indices and Lorenz curves were used in growth monitoring and nutrition promotion among under-5 children.

RESULTS

A weighted prevalence of 33.0% (95%CI: 30.6-35.6%) under-5 children growth monitoring and nutrition promotion was estimated. Growth monitoring and nutrition promotion among under-5 children had higher uptake in the most disadvantaged cohort, as the line of equality sags below the diagonal line in Lorenz curve. Overall, there was pro-poor growth monitoring and nutrition promotion among under-5 in Rwanda (Conc. Index = 0.0994; SE = 0.0111). Across the levels of child and mother's characteristics, the results show higher coverage of under-5 growth monitoring and nutrition promotion in the most socioeconomic disadvantaged cohort.

CONCLUSION

The study found a pro-poor disparity in growth monitoring and nutrition promotion among under-5 children in Rwanda. By implication, the most disadvantaged children had a higher uptake of growth monitoring and nutrition promotion. The Rwanda government should develop policies and programmes to achieve the universal health coverage for the well-off and underserved population.

Socioeconomic Inequalities in Human Immunodeficiency Virus (HIV) Sero-Prevalence among Women in Namibia: Further Analysis of Population-Based Data

Socioeconomic inequality is a major factor to consider in the prevention of human immunodeficiency virus (HIV) transmission. The aim of this study was to investigate socioeconomic inequalities in HIV prevalence among Namibian women. Data from a population-based household survey with multistage-stratified sample of 6501 women were used to examine the link between socioeconomic inequalities and HIV prevalence. The weighted HIV prevalence was 13.2% (95% CI: 12.1–14.3%). The HIV prevalence among the poorest, poorer, middle, richer, and richest households was 21.4%, 19.7%, 16.3%, 11.0%, and 3.7%, respectively. Similarly, 21.2%, 21.7%, 11.8%, and 2.1% HIV prevalence was estimated among women with no formal education and primary, secondary, and higher education, respectively. Women from poor households (Conc. Index = −0.258; SE = 0.017) and those with no formal education (Conc. Index = −0.199; SE = 0.015) had high concentration of HIV infection, respectively. In light of these findings, HIV prevention strategies must be tailored to the specific drivers of transmission in low socioeconomic groups, with special attention paid to the vulnerabilities faced by women and the dynamic and contextual nature of the relationship between socioeconomic status and HIV infection.

Prevalence and Socioeconomic Inequalities in Eight or More Antenatal Care Contacts in Ghana: Findings from 2019 Population-Based Data

Background

For the prevention of complications and death during pregnancy, adequate antenatal care (ANC) contacts are important. To achieve optimal obstetric care, the latest ANC guidance recommends eight or more ANC contacts. The aim of this analysis is to investigate the prevalence and socio-economic differences of eight or more Ghanaian ANC contacts.

Methods

A total sample of 1404 women of reproductive age who had given birth after eight or more ANC contacts had been initiated, taking into account 9 months of gestation, was studied. The Ghana Malaria Indicator Survey of 2019 (GMIS) was used. In the univariate analysis, percentage was used. The curve and concentration index of Lorenz were used to assess socio-economic disparities for eight or more ANC contacts. Statistical significance was set at 5%.

Results

The weighted prevalence of eight or more ANC contacts was 41.9% (95% CI: 37.9–45.9%). The prevalence of eight or more ANC contacts among the poorest, poorer, middle, richer and richest households was 34.0%, 36.1%, 35.8%, 42.4% and 59.6%, respectively. Similarly, 33.0%, 37.7% and 42.6% prevalence of eight or more ANC contacts were estimated among women with no formal education, primary, secondary or higher, respectively. In addition, women from rich household had greater coverage of eight or more ANC contacts (Conc. Index= 0.089; SE= 0.019) and educated women had greater coverage of eight or more ANC contacts in Ghana (Conc. Index= 0.053; SE= 0.017) (all p<0.001).

Conclusion

Eight or more ANC contacts from the WHO in 2016 have yet to be fully institutionalized in Ghana. In order to increase access to the recommended prenatal care and for a healthy pregnancy experience, measures that resolve disparities in healthcare usage need to be prioritized for the country. Efforts should be made to expand the health insurance services available, as well as to enact policies that will increase free health care particularly among the poor and uneducated women.

Socioeconomic inequalities in hidden hunger, undernutrition, and overweight among under-five children in 35 sub-Saharan Africa countries

Background

Many underlying factors are assumed to contribute to the disparities in magnitude of childhood malnutrition. Notwithstanding, socioeconomic inequalities remain key measures to determine chronic and hidden hunger among under-five children. This study was undertaken to explore childhood malnutrition problems that are associated to household wealth-related and mother’s educational attainment in sub-Saharan Africa (SSA).

Methods

Secondary data from birth histories in 35 SSA countries was used. The Demographic and Health Survey (DHS) data of 384,747 births between 2008 and 2017 in 35 countries was analyzed. The outcome variables of interest were mainly indicators of malnutrition: stunting, underweight, wasting, overweight, anemia, and under-five children survival. Household wealth-related and mother’s educational level were the measures of socioeconomic status. Concentration index and Lorenz curves were the main tools used to determine inequalities for nutritional outcomes. The statistical significance level was determined at 5%.

Results

Based on the results, Burundi (54.6%) and Madagascar (48.4%) accounted for the highest prevalence of stunted children. Underweight children were 32.5% in Chad and 35.5% in Niger. Nigeria (16.6%) and Benin (16.4%) had the highest burdens of wasted children. Overall, overweight and under-five survival were significantly more in the higher household wealth, compared with the lower household wealth (Conc. Index = 0.0060; p < 0.001 and Conc. Index = 0.0041; p = 0.002 respectively). Conversely, stunting (Conc. Index = − 0.1032; p < 0.001), underweight (Conc. Index = − 0.1369; p < 0.001), wasting (Conc. Index = − 0.0711; p < 0.001), and anemia (Conc. Index = − 0.0402; p < 0.001) were significantly lower in the higher household wealth status, compared with the lower household wealth groups. Furthermore, under-five children survival was significantly more from mothers with higher educational attainment, compared with children from mothers with lower educational attainment (Conc. Index = 0.0064; p < 0.001). Conversely, stunting (Conc. Index = − 0.0990; p < 0.001), underweight (Conc. Index = − 0.1855; p < 0.001), wasting (Conc. Index = − 0.1657; p < 0.001), overweight (Conc. Index = − 0.0046; p < 0.001), and anemia (Conc. Index = 0.0560; p < 0.001) were significantly more among children from mothers with lower educational attainment. The test for differences between children from urban vs. rural was significant in stunted, underweight, overweight, and anemia for household wealth status. Also, the difference in prevalence between children from urban vs. rural was significant in stunted, underweight, and wasted for mother’s educational attainment.

Conclusion and recommendations

Reduction in malnutrition could be achieved by socioeconomic improvement that is sustained and shared in equity and equality among the populace. Interventions which target improvement in food availability can also help to achieve reduction in hunger including communities where poverty is prevalent.

Trends in utilisation and inequality in the use of reproductive health services in Sub-Saharan Africa

BACKGROUND

The paper argues that unlike the income literature, the public health literature has not paid much attention to the distribution of substantial improvements in health outcomes over the last decade or more, especially, in the Sub-Saharan African (SSA) context. Thus, the paper examines current levels of utilisation, changes in utilisation as well as inequality in utilisation of reproductive health services over the last 10 years in SSA.

METHODS

The paper uses two rounds of Demographic and Health Survey (DHS) data from 30 SSA countries (latest round) and 21 countries (earlier round) to compute simple frequencies, cross-tabulated frequencies and concentration indices for health facility deliveries, skilled delivery assistance, 4+ antenatal visits and use of modern contraceptives.

RESULTS

The results confirm the fact that utilisation of the selected reproductive health services have improved substantially over the last 10 year in several SSA countries. However, current levels of inequality in the use of reproductive health services are high in many countries. Interestingly, Guinea's pro-poor inequality in health facility delivery and skilled attendance at birth changed to pro-rich inequality, with the reverse being true in the case of use of modern contraceptives for Ghana, Malawi and Rawanda. The good news however is that in a lot of countries, the use of reproductive health services has increased while inequality has decreased within the period under study.

CONCLUSION

The paper argue that whiles income levels may play a key role in explaining the differences in utilisation and the levels of inequality, indepth studies may be needed to explain the reason for differential improvements and stagnation or deterioration in different countries. In this way, best practices from better performing countries can be documented and adapted by poor performing countries to improve their situation.

A Decomposition Analysis of Inequality in Malnutrition among Under-Five Children in Iran: Findings from Multiple Indicator Demographic and Health Survey, 2010

BACKGROUND

Nutritional status at the early stages of children's lives is essential for growth and development not only in infancy but also in adult life. This study aimed to measure the inequality in malnutrition among under-five children in Iran and explore the impact of socioeconomic factors on this inequality using a regression-based decomposition approach.

METHODS

Data were extracted from Iran's Multiple-Indicator Demographic and Health Survey 2010. The concentration index of stunting, underweight, and wasting were applied in order to measure the magnitude of socioeconomic inequality in child malnutrition. Moreover, the concentration indices were decomposed to understand the contribution of socioeconomic variables in childhood malnutrition inequality.

RESULTS

The obtained concentration indices of stunting, underweight, and wasting were respectively -0.177, -0.092, and -0.031. Socioeconomic inequality in stunting and underweight was statistically significant, however this socioeconomic gradient was not observed in wasting. More than 50% of the inequality in stunting and about 63% of the inequality in underweight were influenced by socioeconomic status. Furthermore, maternal education was associated with 19% and 22% of inequality in stunting and underweight respectively.

CONCLUSION

The average reduction of malnutrition indices at the national level hides the burden of malnutrition among children in poor families. If government and policymakers seek to solve this problem, they have to take direct and targeted actions to eliminate the existing inequalities in the socioeconomic determinants associated with malnutrition.

Statistical inferences of extended concentration indices for directly standardized rates

The relative concentration index (RCI) and the absolute concentration index (ACI) have been widely used for monitoring health disparities with ranked health determinants. The RCI has been extended to allow value judgments about inequality aversion by Pereira in 1998 and by Wagstaff in 2002. Previous studies of the extended RCI have focused on survey sample data. This paper adapts the extended RCI for use with directly standardized rates (DSRs) calculated from population-based surveillance data. A Taylor series linearization (TL)-based variance estimator is developed and evaluated using simulations. A simulation-based Monte Carlo (MC) variance estimator is also evaluated as a comparison. Following Wagstaff's approach in 1991, we extend the ACI for use with DSRs. In all simulations, both the TL and MC methods produce valid variance estimates. The TL variance estimator has a simple, closed form that is attractive to users without sophisticated programming skills. The TL and MC estimators have been incorporated into a beta version of the National Cancer Institute's Health Disparities Calculator, a free statistical software tool that enables the estimation of 11 commonly used summary measures of health disparities for DSRs.

Treatment Outcome of Severe Acute Malnutrition and Its Determinants among Pediatric Patients in West Ethiopia

Background

Malnutrition is a silent killer that is underreported, underaddressed, and as a result underprioritized. It is reported that severe acute malnutrition is the commonest reason for pediatrics hospital admission in many poor countries; 25 to 30% of children with severe malnutrition die during hospital admissions.

Objective

To determine treatment outcome of severe acute malnutrition and identify its determinants among pediatric patients in pediatrics ward of Nekemte Referral Hospital.

Methods

A retrospective hospital-based cross-sectional study was done from November 2015 to April 2017. Data had been collected by using checklist for recording information from patient card and register book. Association between independent variables and depend variable was assessed using bivariate and stepwise multivariable logistic regression, respectively. Level of statistical significance was declared at p value < 0.05.

Results

Out of 205 admitted children with severe acute malnutrition, 137 (66.8%) cases were cured from SAM, 9 (4.4%) cases were died because of SAM, and (16.6%) cases were defaulter from SAM management, and 25 (12.2%) cases were transferred out. Multivariable logistic regression showed that children admitted with both edema and wasting AOR = 8.30, 95% CI (1.72, 40.09) P=0.008, children without hypothermia AOR = 2.91, 95%CI (1.10, 7.69) P=0.031, children who stay 8-14 days AOR = 3.86, 95%CI (1.01, 14.75) P=0.048, children without pneumonia AOR = 7.82, 95%CI (2.74, 222.29) P=0.001, children without anemia AOR = 3.22, 95%CI (1.04, 9.97) P=0.042, and children without HIV AOR = 9.21, 95% CI (2.20, 38.54) P=0.002 were more likely to be cured from severe acute malnutrition.

Conclusion

Treatment outcome of severe acute malnutrition in this study is good. It shows that around three-fourths of the children were cured. Factors such as admission criteria, hypothermia, length of stay, pneumonia, anemia, and presence of HIV were associated with treatment response.

Socioeconomic Inequality in Malnutrition in Under-5 Children in Iran: Evidence From the Multiple Indicator Demographic and Health Survey, 2010

Objectives

The aim of this study was to assess the socioeconomic inequality in malnutrition in under-5 children in Iran in order to help policymakers reduce such inequality.

Methods

Data on 8443 under-5 children were extracted from the Iran Multiple Indicator Demographic and Health Survey. The wealth index was used as proxy for socioeconomic status. Socioeconomic inequality in stunting, underweight, and wasting was calculated using the concentration index. The concentration index was calculated for the whole sample, as well as for subcategories defined in terms of categories such as area of residence (urban and rural) and the sex of children.

Results

Stunting was observed to be more prevalent than underweight or wasting. The results of the concentration index at the national level, as well as in rural and urban areas and in terms of children’s sex, showed that inequality in stunting and underweight was statistically significant and that children in the lower quintiles were more malnourished. The wasting index was not sensitive to socioeconomic status, and its concentration index value was not statistically significant.

Conclusions

This study showed that it can be misleading to assess the mean levels of malnutrition at the national level without knowledge of the distribution of malnutrition among socioeconomic groups. Significant socioeconomic inequalities in stunting and underweight were observed at the national level and in both urban and rural areas. Regarding the influence of nutrition on the health and economic well-being of preschool-aged children, it is necessary for the government to focus on taking targeted measures to reduce malnutrition and to focus on poorer groups within society who bear a greater burden of malnutrition.

Income-related children's health inequality and health achievement in China

Introduction

This study assessed income–related health inequality and health achievement in children in China, and additionally, examined province-level variations in health achievement.

Methods

Longitudinal data on 19,801 children under 18 years of age were derived from the China Health and Nutrition Survey. Income–related health inequality and health achievement were measured by the Health Concentration and Health Achievement Indices, respectively. Panel data with a fixed effect multiple regression model was employed to examine province-level variations in health achievement.

Results

A growing trend was towards greater health inequality among Chinese children over the last two decades. Although health achievement was getting better over time, the pro-rich inequality component has lessened the associated gain in achievement. Health achievement was positively impacted by middle school enrollments, the urbanization rate, inflation-adjusted per capita gross domestic product, and per capita public health spending.

Conclusion

This study has provided evidence that average health status of Chinese children has improved, but inequality has widened. Widening inequality slowed the growth in health achievement for children over time. There were wide variations in health achievement throughout China.

Mother's education is the most important factor in socio-economic inequality of child stunting in Iran

OBJECTIVE

Malnutrition is one of the most important health problems, especially in developing countries. The present study aimed to describe the socio-economic inequality in stunting and its determinants in Iran for the first time.

DESIGN

Cross-sectional, population-based survey, carried out in 2009. Using randomized cluster sampling, weight and height of children were measured and anthropometric indices were calculated based on child growth standards given by the WHO. Socio-economic status of families was determined using principal component analysis on household assets and social specifications of families. The concentration index was used to calculate socio-economic inequality in stunting and its determinants were measured by decomposition of this index. Factors affecting the gap between socio-economic groups were recognized by using the Oaxaca-Blinder decomposition method.

SETTING

Shahroud District in north-eastern Iran.

SUBJECTS

Children (n 1395) aged <6 years.

RESULTS

The concentration index for socio-economic inequality in stunting was -0·1913. Mother's education contributed 70 % in decomposition of this index. Mean height-for-age Z-score was -0·544 and -0·335 for low and high socio-economic groups, respectively. Mother's education was the factor contributing most to the gap between these two groups.

CONCLUSIONS

There was a significant socio-economic inequality in the studied children. If mother's education is distributed equally in all the different groups of Iranian society, one can expect to eliminate 70 % of the socio-economic inequalities. Even in high socio-economic groups, the mean height-for-age Z-score was lower than the international standards. These issues emphasize the necessity of applying new interventions especially for the improvement of maternal education.

Understanding inequalities in child health in Ethiopia: health achievements are improving in the period 2000-2011

Objective

In Ethiopia, coverage of key health services is low, and community based services have been implemented to improve access to key services. This study aims to describe and assess the level and the distribution of health outcomes and coverage for key services in Ethiopia, and their association with socioeconomic and geographic determinants.

Methods

Data were obtained from the 2000, 2005 and 2011 Ethiopian Demographic and Health Surveys. As indicators of access to health care, the following variables were included: Under-five and neonatal deaths, skilled birth attendance, coverage of vaccinations, oral rehydration therapy for diarrhoea, and antibiotics for suspected pneumonia. For each of the indicators in 2011, inequality was described by estimating their concentration index and a geographic Gini index. For further assessment of the inequalities, the concentration indices were decomposed. An index of health achievement, integrating mean coverage and the distribution of coverage, was estimated. Changes from 2000 to 2011 in coverage, inequality and health achievement were assessed.

Results

Significant pro-rich inequalities were found for all indicators except treatment for suspected pneumonia in 2011. The geographic Gini index showed significant regional inequality for most indicators. The decomposition of the 2011 concentration indices revealed that the factor contributing the most to the observed inequalities was different levels of wealth. The mean of all indicators improved from 2000 to 2011, and the health achievement index improved for most indicators. The socioeconomic inequalities seem to increase from 2000 to 2011 for under-five and neonatal deaths, whereas they are stable or decreasing for the other indicators.

Conclusion

There is an unequal socioeconomic and geographic distribution of health and access to key services in Ethiopia. Although the health achievement indices improved for most indicators from 2000 to 2011, socioeconomic determinants need to be addressed in order to achieve better and more fairly distributed health.

Revealing mental health status in Iran's capital: putting equity and efficiency together

Information about urban health is often based on averages, while to better understand health status in urban areas, inequality should also be included. In this paper, we applied an achievement index approach in order to surmount this defect and to examine mental health status in Iran's capital, Tehran. The data we required for this study were taken from the Urban Health Equity Assessment and Response Tool (Urban HEART) survey which was conducted in Tehran in 2007, covering people aged 15 and above. The concentration index, which is a commonly used measure of socioeconomic inequalities in health, was extended to enable the combination of inequality and averages and the formation of a mental health achievement index. Values from the standard concentration indices showed that mental disorders are concentrated disproportionately among the poor in Tehran. An extension of the standard concentration indices revealed that, in most of Tehran's districts, the mental health of populations in the poorest quintile is much worse than that of other groups. In addition, when we computed the achievement index and ranked districts according to this index, the ranking was different from the ranking by averages. These findings imply that mental health varies significantly across the economic groups of the population in Tehran and that efficiency-oriented strategies which target average level of mental health alone are not sufficient to improve mental health of all people especially mental health of the poor. Equity-oriented strategies which target the mental health inequalities should be considered as well.

"Mirror, mirror, on the wall, who in this land is fairest of all?"--Distributional sensitivity in the measurement of socioeconomic inequality of health

This paper explores four alternative indices for measuring health inequalities in a way that takes into account attitudes towards inequality. First, we revisit the extended concentration index which has been proposed to make it possible to introduce changes into the distributional value judgements implicit in the standard concentration index. Next, we suggest an alternative index based on a different weighting scheme. In contrast to the extended concentration index, this new index has the 'symmetry' property. We also show how these indices can be generalized so that they satisfy the 'mirror' property, which may be seen as a desirable property when dealing with bounded variables. We compare the different indices empirically for under-five mortality rates and the number of antenatal visits in developing countries.

Prevalence and socio-demographic correlates of stunting and thinness among Pakistani primary school children

Background

Child growth is internationally recognized as an important indicator of nutritional status and health in populations. Child under-nutrition is estimated to be the largest contributor to global burden of disease, and it clusters in South Asia but literature on under-nutrition among school-aged children is difficult to find in this region. The study aimed to assess the prevalence and socio-demographic correlates of stunting and thinness among Pakistani primary school children.

Methods

A population-based cross-sectional study was conducted with a representative multistage cluster sample of 1860 children aged 5-12 years in Lahore, Pakistan. Stunting (< -2 SD of height-for-age z-score) and thinness (< -2 SD of BMI-for-age z-score) were defined using the World Health Organization reference 2007. Chi-square test was used as the test of trend. Logistic regression was used to quantify the independent predictors of stunting and thinness and adjusted odds ratios (aOR) with 95% confidence interval (CI) were obtained. Linear regression was used to explore the independent determinants of height- and BMI-for-age z-scores. Statistical significance was considered at P < 0.05.

Results

Eight percent (95% CI 6.9-9.4) children were stunted and 10% (95% CI 8.7-11.5) children were thin. Stunting and thinness were not significantly associated with gender. Prevalence of stunting significantly increased with age among both boys and girls (both P < 0.001) while thinness showed significant increasing trend with age among boys only (P = 0.034). Significant correlates of stunting included age > 8 years, rural area and urban area with low SES, low-income neighborhoods, lower parental education, more siblings, crowded housing and smoking in living place (all P < 0.001). Significant correlates of thinness included rural area and urban area with low SES, low-income neighborhoods and lower parental education (all P < 0.001), and age > 10 years (P = 0.003), more siblings (P = 0.016) and crowded housing (P = 0.006). In multivariate logistic regression analyses adjusted simultaneously for all factors, older age (aOR 3.60, 95% CI 1.89-6.88), urban area with low SES (aOR 2.58, 95% CI 1.15-5.81) and low-income neighborhoods (aOR 4.62, 95% CI 1.63-13.10) were associated with stunting while urban area with low SES (aOR 2.28, 95% CI 1.21-4.30) was associated with thinness. In linear regression analyses adjusted for all factors, low-income neighborhoods and older age were associated with lower height-for-age z-score while rural area with low/disadvantaged SES was associated with lower BMI-for-age z-score.

Conclusions

Relatively low prevalence of stunting and thinness depicted an improvement in the nutritional status of school-aged children in Pakistan. However, the inequities between the poorest and the richest population groups were marked with significantly higher prevalence of stunting and thinness among the rural and the urban poor, the least educated, the residents of low-income neighborhoods and those having crowded houses. An increasing trend with age was observed in prevalence of stunting and thinness. Smoking in living place was associated with stunting. Findings suggest the need to implement evidence-based child health policy and strategies, prioritizing the poor and socially disadvantaged population.
