Education and non-communicable diseases in India: an exploration of gendered heterogeneous relationships

BACKGROUND

While the association between education and non-communicable diseases (NCDs) is well established, it remains unclear whether this association varies by gender. The aim of this study was to examine two critical research questions: whether the association of education and NCDs is conditioned by gender and, if so, what are the factors contributing to this?

METHODS

Data from the Longitudinal Aging Study in India Wave 1 (2017-2018) was used for the empirical analysis. The study employs bivariate, binary logistic regression and Oaxaca decomposition analyses.

RESULTS

The results reveal that the net likelihood of having at least one chronic NCD increases with an increase in education level for men (<5 y of schooling: odds ratio [OR] 1.18 [95% confidence interval {CI} 1.09 to 1.28]; ≥10 y of schooling: OR 1.43 [95% CI 1.33 to 1.53]). However, for women, the result showed a contrasting pattern. The decomposition analysis revealed that the distinctive roles of marital status and working status in the diagnosis of morbidity for men and women are the key factors behind the gendered heterogeneous relationship of education and NCDs in India.

CONCLUSIONS

The study found that it is important to acknowledge the potential impact of self-reporting bias in morbidity data while examining the relationship between education and NCDs.

Widowhood status, morbidity, and mortality in India: evidence from a follow-up survey

A known health effect of widowhood is an increased mortality risk among surviving spouses, with gender- and age-specific observations. While morbidity conditions with socio-economic factors may exacerbate the effect of widowhood on mortality, no research has attempted to predict mortality among the widowed over the married population with the presence of morbidity in India. Thus, the present study concurrently examines marital status and health in the Indian setting, bringing substantial empirical evidence to explore the link between marital status, morbidity, and mortality. The study used prospective data from India Human Development Survey (IHDS) wave 1 (2004-2005) and wave 2 (2011-2012). In total, 82,607 individuals aged 25 years and above were considered for the analysis. To present the preliminary findings, descriptive statistics and bivariate analysis were used. Using multivariable logistic regression, the interaction effect of marital status and morbidity status was estimated to predict the likelihood of mortality. Across all socio-economic groups, widowed individuals reporting any morbidity had a higher mortality proportion than married people. Young widowers with any morbidity are more susceptible to increased mortality. Asthma among young widowers and cardiovascular diseases among elderly widowers significantly elevate the probability of mortality. However, older widowed women with diabetes had a lower probability of mortality than older married women with diabetes. The widowers' disadvantage in mortality and morbidity may be attributable to less care-receiving and the greater incidence of unhealthy lifestyle practices during the post-widowhood period, indicating the need for more research.

A qualitative perspective of working women care providers and care receivers on eldercare: a study from India

BACKGROUND

The paper aims to explore the elderly caregiving process in India from the perspective of both elderly as well as working women care providers, along with the challenges faced and the coping strategies adopted by them during the process.

METHODS

In-depth interviews with 48 participants (care providers and care receivers) from 25 multi-generational households were conducted in the slums of Mumbai and analysed using QSR-NVivo-10.

RESULTS

Working women care providers supported the needs of the dependent elderly along with performing household chores and paid work. However, the way the care was perceived and demanded, was not often same as delivered by the care providers. Care provider suffered silently with poor social, physical and emotional welling in absence of support system and lack of time. Sometimes, physically exhausted care providers unknowingly resorted to elderly abuse and neglect. At the same time, a bidirectional flow of support from elderly also existed in the form of childcare, household chores and financial support. Though caregiving overstrained the care providers, strong family ties, acknowledgement of the contributions of the elderly during their young days, and the desire to set a precedent for the young generation did not let them step back from their duties. The main coping mechanism for both care receivers and providers was largely centred around the notion of acceptance of their situation.

CONCLUSION

Conversations between generations can help in enhancing family ties and reduce conflicts. The support of family and community can also ease the burden of caregiving.

Economics of widowhood mortality in adult women in India

The economic consequence of widowhood on health is well-established, demonstrating that economic factors can significantly link with health outcomes, even the risk of mortality for widows. However, empirical evidence is restricted only to developed countries. Thus, this study assesses the role of economic factors (paid work, pension and household economic status) on the mortality of widows in broad age groups in India. We used two waves of the India Human Development Survey (IHDS), a nationally representative prospective dataset in India for 42,009 women (married and widows) aged 25 years and above at IHDS wave 1 whose survival status was observed between two waves. Further, 6,953 widows were considered for sub-sample analysis in this study. Logistic regression and propensity score matching (PSM) were applied to understand the association and causality between economic factors and mortality for widows. Poor household economic status, paid regular work, and receiving a widowed pension were significantly associated with lower mortality risk for young widows. In comparison, unpaid and paid regular work was linked with lower mortality risk for old widows. The result of causal analysis suggests that receiving a widows' pension had a slight impact on mortality reduction for young widows while engaging in paid regular work significantly reduced the mortality of old widows. This research confirms that the link between economic factors and mortality among widows is age dependent in the Indian context.

Key drivers of reversal of trend in childhood anaemia in India: evidence from Indian demographic and health surveys, 2016-21

AIM

Recent National Family Health Survey results portray striking improvements in most population and health indicators, including fertility, family planning, maternal and child health, gender treatment, household environments, and health insurance coverage of the Pradhan Mantri Jan Arogya Yojana (PM-JAY), with all India resonance. However, the prevalence of any anaemia (< 11 g/dl) among children under age five has exhibited a reversed trajectory in recent years. Therefore, the present study explores key drivers of the reversal of the trend in the prevalence of childhood anaemia between 2015 and2021.

METHODS

Data of four rounds of the National Family Health Survey (NFHS) were used to show the overall trend of anaemia among children. However, for the analysis of key drivers of the reversal trend of childhood anaemia, only the recent two rounds (NFHS-4 & NFHS-5) were used. Descriptive, bivariate multivariable analysis and Fairlie decomposition model were used to explore the drivers of the reversal of the trend in childhood anaemia.

RESULTS

During the past two decades, India has seen a decline in the prevalence of childhood anaemia (NFHS-2 to NFHS-4). However, a reversal of trend was observed recently. The prevalence of anaemia among children aged 6-59 months increased from 59 percent in NFHS-4 to 67 percent in NFHS-5. In addition, the prevalence of mild anaemia increased from 23.3 percent in NFHS-2 to 28.7 percent in NFHS-5. However, the prevalence of moderate and severe anaemia declined considerably from NFHS-2 (40 percent and 4.1 percent) to NFHS-4 (28.7 percent and 1.6 percent), but showed an increase in the prevalence in NFHS-5 (36.3 percent and 2.2 percent). Among others, mothers' educational attainment, anaemia status and socio-economic status emerge as the key drivers of the change in the prevalence of childhood anaemia.

CONCLUSION

These findings may have vital implications for the ongoing Anaemia Mukt Bharat Programme, one of the government's dream projects in India.

Gender differences in premature mortality for cardiovascular disease in India, 2017-18

BACKGROUND

The present study tries to provide a comprehensive estimate of gender differences in the years of life lost due to CVD across the major states of India during 2017-18.

METHODS

The information on the CVD related data were collected from medical certification of causes of death (MCCD reports, 2018). Apart from this, information from census of India (2001, 2011), SRS (2018) were also used to estimate YLL. To understand the variation in YLL due to CVD at the state level, nine sets of covariates were chosen: share of elderly population, percentage of urban population, literacy rate, health expenditure, social sector expenditure, labour force participation, HDI Score and co-existence of other NCDs such as diabetes, & obesity. The absolute number of YLL and YLL rates were calculated. Further, Pearson's correlation had been calculated and to understand the effect of explanatory variables on YLL due to CVD, multiple linear regression analysis had been applied.

RESULTS

Men have a higher burden of premature mortality in terms of Years of life lost (YLL) due to CVD than women in India, with pronounced differences at adult ages of 50-54 years and over. The age pattern of YLL rate suggests that the age group 85 + makes the highest contribution to the overall YLL rate due to CVD. YLL rate showed a J-shaped relationship with age, starting high at ages below 1 years, dropping to their lowest among children aged 1-4 years, and rising again to highest levels at 85 + years among both men and women. In all the states except Bihar men had higher estimated YLL due to CVD for all ages than women. Among men the YLL due to CVD was higher in Tamil Nadu followed by Madhya Pradesh and Chhattisgarh. On the other hand, the YLL due to CVD among men was lowest in Jharkhand followed by Assam. Similarly, among women the YLL due to CVD was highest in Tamil Nadu followed by Madhya Pradesh and Chhattisgarh. While, the YLL due to CVD among women was lowest in Jharkhand. Irrespective of gender, all factors except state health expenditure were positively linked with YLL due to CVD, i.e., as state health expenditure increases, the years of life lost (YLL) due to CVDs falls. Among all the covariates, the proportion of a state's elderly population emerges as the most significant predictor variable for YLL for CVDs (r = 0.42 for men and r = 0.50 for women).

CONCLUSION

YLL due to cardiovascular disease varies among men and women across the states of India. The state-specific findings of gender differences in years of life lost due to CVD may be used to improve policies and programmes in India.

Differentials in private and public healthcare service utilization in later life: do gender and marital status have any association?

The present study investigates whether the differentials in private and public inpatient healthcare utilization are associated with marital status for men and women aged 60 years and above in India. Binary logistic regression was applied to examine the association of private and public inpatient healthcare utilization with the marital status of the elderly. The study found that widowed men and women generally used public healthcare for hospitalization, while married men and women preferred private healthcare. Our findings also indicated that private inpatient health services expenditure was higher for married elderly than widowed elderly. After controlling all covariates, widowhood was significantly associated with higher use of public healthcare services for women but not for men. India's current health care policy and program may be required to focus on improving the infrastructure quality of current public healthcare systems. It also needs to be favorable for vulnerable sections of society, especially widowed women, to avail better treatment at an affordable cost.

Interpregnancy Interval and Child Health Outcomes in India: Evidence from Three Recent Rounds of National Family Health Survey

INTRODUCTION

Short interpregnancy interval (IPI) is a well-known risk factor for preterm births and low birth weights. However, research on the association between interpregnancy interval (IPI) and health outcomes in children under age 5 is limited in India. We examined the associations between IPI and five child health outcomes in India.

METHODS

We used nationally representative cross-sectional data from three rounds of National Family Health Survey (NFHS) conducted in India during 2005-06, 2015-16 and 2019-21 to examine the associations between IPI [categorized as < 12 months, 12-17 months, 18-23 months (ref), 24-35 months, and 36-59 months] and five child health outcomes - neonatal mortality, postneonatal mortality, diarrhea and/or acute respiratory infections (ARI), stunting, and underweight, for the total sample and, secondarily, using sex-stratified analyses. We used multivariable and mother fixed-effects binary logistic regressions to examine the associations.

RESULTS

3% and 2% of infants died during the neonatal and postneonatal period, respectively. Thirteen, 40, and 37% of children had diarrhea and/or ARI, were stunted, and were underweight, respectively. IPI < 12 months was associated with higher odds of diarrhea and/or ARI (OR: 1.11; 95% CI: 1.05-1.18), stunting (OR: 1.13; 95% CI: 1.08-1.18) and underweight (OR: 1.06; 95% CI: 1.01-1.11). Mother fixed-effects adjustments confirmed these associations and also found that births with IPI of 12-17 months and 36-59 months had higher odds of stunting, and IPI of 12-17 months was also associated with higher odds of underweight.

DISCUSSION

Our findings indicate that IPIs shorter than 12 months are a risk factor for diarrhea and/or ARI, and IPIs shorter than 12 months and 12-17 months are risk factors for stunting and underweight among children under 5 in India. Mother fixed-effects models allowed us to adjust our estimates for unobserved heterogeneity; this has rarely been done before. Increases in birth spacing may improve child health outcomes in India.

Moderation of marital status and living arrangements in the relationship between social participation and life satisfaction among older Indian adults

Social participation is considered one of the central components of successful and healthy aging. This study aimed to examine the moderating role of marital status and living arrangement with social participation and its association with life satisfaction of older Indian adults. Samples of 31,464 individuals aged ≥ 60 years were extracted from the Longitudinal Ageing Study in India, wave-1. Descriptive statistics, bivariate analysis, and multivariable linear regression were performed for the analysis. The moderation effect of marital status and living arrangements on the relationship between social participation and level of life satisfaction among Indian older adults were also analyzed. Overall, life satisfaction among older men was relatively higher than older women in this study. Older adults' involvement in social participation [β = 0.39, p < 0.05], being in marital union [β = 0.68, p < 0.001] and co-residing either with spouse [β = 1.73, p < 0.001] or with other family members [β = 2.18, p < 0.001] were positively related to their greater life satisfaction. Interaction of social participation with marital status showed that participating in social activities can boost life satisfaction only among married older people. Further, moderation effect of social participation with living arrangements showed that older adults who were not involved in social participation but living with a spouse or any other household members had higher life satisfaction, and again participation in social activities increased their life satisfaction to a greater level. The establishment of social clubs and advocating social policies oriented toward meaningful social connections are highly needed, especially for older Indians living alone or currently not in a marital union, which will help to enhance their overall life satisfaction.

Association between poor self-reported health and unmarried status among adults: examining the hypothesis of marriage protection and marriage selection in the Indian context

Background

The link between marital status and health differences has long been a topic of debate. The substantial research on marriage and health has been conducted under two important hypotheses: marital protection and marriage selection. While the majority of evidence on the marriage-health relationship using these hypotheses comes from developed countries, there is a lack of evidence from Asia, particularly from India.

Objectives

The current study examines theoretical frameworks of marriage i.e., marital protection and marriage selection in the Indian setting concurrently, bringing substantial empirical evidence to explore the link between marriage and health, considering this subject in the context of self-reported health (SRH). Secondly, this study will aid in investigating age and gender differences in marriage and health.

Methods

Using the Study on Global AGEing and Adult Health (SAGE), a cohort study of individuals aged 50 years and older with a small section of individuals aged 18 to 49 for comparative reasons, the present study population was 25 years and above individuals with complete marital information. Logistic regressions were employed to explore the connection between marital status and self-reported health. In the marriage protection hypothesis, the follow-up poor SRH was the dependent variable, whereas the initial unmarried status was the independent variable. For the marriage selection effects, initial poor SRH as the independent variable and follow-up unmarried status as the dependent variable had considered.

Results

Examining the marital protection hypothesis, the initial unmarried status (OR: 2.14; CI at 95%: 1.17, 3.92) was associated with the followed-up SRH transition from good to poor between 2007 and 2015 for young men, while initial unmarried status was linked with a lower likelihood of stable good SRH and a higher likelihood of stable poor SRH status across all age categories among women. Focusing on the marriage selection hypothesis, among young men, a significant association exists between the initial poor SRH and departure in marital status from married to unmarried. Young women with initial poor SRH (OR: 0.68; CI at 95%: 0.40, 1.00) had lower odds of stable married. In comparison, women with initially poor SRH, irrespective of age, were more likely to have higher odds of being stably unmarried.

Conclusion

Marriage indeed protects health. There are also shreds of evidence on health-selected marital status in India. Taken together, the aspect of marital protection or marriage selection is gender and age-specific in India. The findings contribute to a more comprehensive understanding of the relationship between marriage and health, which may have significant implications for health-related public policies aimed at unmarried women.

Small area variations in low birth weight and small size of births in India

The states and districts are the primary focal points for policy formulation and programme intervention in India. The within‐districts variation of key health indicators is not well understood and consequently underemphasised. This study aims to partition geographic variation in low birthweight (LBW) and small birth size (SBS) in India and geovisualize the distribution of small area estimates. Applying a four‐level logistic regression model to the latest round of the National Family Health Survey (2015–2016) covering 640 districts within 36 states and union territories of India, the variance partitioning coefficient and precision‐weighted prevalence of LBW (<2.5 kg) and SBS (mother's self‐report) were estimated. For each outcome, the spatial distribution by districts of mean prevalence and small area variation (as measured by standard deviation) and the correlation between them were computed. Of the total valid sample, 17.6% (out of 193,345 children) had LBW and 12.4% (out of 253,213 children) had SBS. The small areas contributed the highest share of total geographic variance in LBW (52%) and SBS (78%). The variance of LBW attributed to small areas was unevenly distributed across the regions of India. While a strong correlation between district‐wide percent and within‐district standard deviation was identified in both LBW (r = 0.88) and SBS (r = 0.87), they were not necessarily concentrated in the aspirational districts. We find the necessity of precise policy attention specifically to the small areas in the districts of India with a high prevalence of LBW and SBS in programme formulation and intervention that may be beneficial to improve childbirth outcomes.

The small areas contribute the highest share of the total geographic variance of low birth weight (LBW) and small birth size (SBS) in India.

A high burden of LBW is found mostly in the central‐western part of India and Odisha. The prevalence of SBS is high across the district of northern‐western regions and the north‐eastern regions of India.

The mean prevalence and standard deviation are strongly correlated in the case of both LBW (r = 0.88) and SBS (r = 0.87) in India. It indicates that the districts which have a higher prevalence of LBW and SBS also have a higher between small area disparity within the districts.

We find a similar pattern of distribution in LBW and SBS between the policy‐focused aspirational districts and other districts of India.

Findings indicate reprioritizing the policy intervention, focusing on the small areas of India for better childbirth outcomes.

Association between Intimate Partner Violence and Contraceptive Use Discontinuation in India

Research on the association between experiences of intimate partner violence (IPV) and contraceptive use discontinuation in low- and middle-income countries (LMICs) is limited. This study aims to fill this important gap using microdata collected from women aged 15-49 in the 2015-2016 National Family Health Survey (NFHS). Analyses used multivariable multinomial logistic regressions stratified by long-acting reversible contraceptive methods (LARC)/non-LARC and condom/pill to examine the association between experience of IPV and contraceptive use discontinuation while still in need (DWSIN). Experience of physical violence was associated with DWSIN among LARC/IUD users (RRR: 3.73, 95 percent CI [1.55-8.95]) Among condom users, DWSIN was higher among women who experienced emotional violence compared with women who did not experience any violence (RRR: 4.16, 95 percent CI [1.59-10.90]). Although we did not find an association between IPV and overall contraceptive use discontinuation, we did find compelling evidence of an association between IPV and IUD and condom use discontinuation in India. There is a need to understand women's experience of IPV as a part of a broader strategy to provide high-quality family planning services to all women while considering individual circumstances and reproductive aspirations to support the uninterrupted use of contraception in India.

Small Area Variations in Dietary Diversity Among Children in India: A Multilevel Analysis of 6–23-Month-Old Children

Dietary diversity is an important indicator of child malnutrition. However, little is known about the geographic variation of diet indicators across India, particularly within districts and across states. As such, the purpose of this paper was to elucidate the small area variations in diet indicators between clusters within districts of India. Overall, we found that clusters were the largest source of variation for children not eating grains, roots, and tubers, legumes and nuts, dairy, vitamin A-rich vegetables and fruits, and other vegetables and fruits. We also found positive correlations between the district percent and cluster standard deviations of children not breastfeeding or eating grains, roots, and tubers, but negative correlations between the district percent and cluster standard deviation for the remaining seven outcomes. These findings underscore the importance of targeting clusters to improve child dietary diversity.

Estimates and correlates of district-level maternal mortality ratio in India

Despite the progress achieved, approximately one-quarter of all maternal deaths worldwide occur in India. Till now, India monitors maternal mortality in 18 out of its 36 provinces using information from the periodic sample registration system (SRS). The country does not have reliable routine information on maternal deaths for smaller states and districts. And, this has been a major hurdle in local-level health policy and planning to prevent avoidable maternal deaths. For the first time, using triangulation of routine records of maternal deaths under the Health Management Information System (HMIS), Census of India, and SRS, we provide Maternal Mortality Ratio (MMR) for all states and districts of India. Also, we examined socio-demographic and health care correlates of MMR using large-sample and robust statistical tools. The findings suggest that 70% of districts (448 out of 640 districts) in India have reported MMR above 70 deaths-a target set under Sustainable Development Goal-3. According to SRS, only Assam shows MMR of more than 200, while our assessment based on HMIS suggests that about 6-states (and two union territories) and 128-districts have MMR above 200. Thus, the findings highlight the presence of spatial heterogeneity in MMR across districts in the country, with spatial clustering of high MMR in North-eastern, Eastern, and Central regions and low MMR in the Southern and Western regions. Even the better-off states such as Kerala, Tamil Nadu, Andhra Pradesh, Karnataka, and Gujarat have districts of medium-to-high MMR. In order of their importance, fertility levels, the sex ratio at birth, health infrastructure, years of schooling, postnatal care, maternal age and nutrition, and poor economic status have emerged as the significant correlates of MMR. In conclusion, we show that HMIS is a reliable, cost-effective, and routine source of information for monitoring maternal mortality ratio in India and its states and districts.

Effect of preterm birth on early neonatal, late neonatal, and postneonatal mortality in India

Despite India having a high burden of infant deaths and preterm birth, there is a clear lack of studies documenting association between preterm birth and infant mortality in India. Additionally, existing studies have failed to account for unobserved heterogeneity while linking preterm birth with infant mortality. Hence, the present study examines association of preterm birth with early neonatal death (ENND), late neonatal death (LNND), and postneonatal death (PNND) in India. We used the reproductive calendar canvassed in the cross-sectional National Family Health Survey 2015-16 (NFHS-4) to identify preterm births. We used multivariable logistic regression to examine the associations for all births, most-, second most-, and third most- recent births occurred in five years preceding NFHS-4. We use mother fixed-effect logistic regression to confirm the associations among all recent births. Among all births, preterm births were 4.2, 3.8, and 1.7 times as likely as full-term births to die during early neonatal, late neonatal, and postneonatal periods respectively. Among most recent births, preterm births were 4.4, 4.0, and 2.0 times as likely as full-term births to die during early neonatal, late neonatal, and postneonatal periods respectively. Preterm births were also associated with risk of only ENND, LNND, and PNND among the second most recent births. Preterm births were associated with risk of only ENND and LNND among the third most recent births. Preterm births were also associated with ENND, LNND, and PNND in the mother fixed-effects regressions. This study establishes associations of preterm birth with ENND, LNND, and PNND in India using over 0.2 million births that occurred in 5 years preceding one of the largest population-based representative household surveys conducted in any part of the world. Our findings call for programmatic and policy interventions to address the considerable burden of preterm birth in the country.

Estimating the Burden of Child Undernutrition for Smaller Electoral Units in India

IMPORTANCE

Geographic targeting of public health interventions is needed in resource-constrained developing countries.

OBJECTIVE

To develop methods for estimating health and development indicators across micropolicy units, using assembly constituencies (ACs) in India as an example.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study included children younger than 5 years who participated in the fourth National Family and Health Survey (NFHS-4), conducted between January 2015 and December 2016. Participants lived in 36 states and union territories and 640 districts in India. Children who had valid weight and height measures were selected for stunting, underweight, and wasting analysis, and children between age 6 and 59 months with valid blood hemoglobin concentration levels were included in the anemia analysis sample. The analysis was performed between February 1 and August 15, 2020.

EXPOSURES

A total of 3940 ACs were identified from the geographic location of primary sampling units in which the children's households were surveyed in NFHS-4.

MAIN OUTCOMES AND MEASURES

Stunting, underweight, and wasting were defined according to the World Health Organization Child Growth Standards. Anemia was defined as blood hemoglobin concentration less than 11.0 g/dL.

RESULTS

The main analytic sample included 222 172 children (mean [SD] age, 30.03 [17.01] months; 114 902 [51.72%] boys) from 3940 ACs in the stunting, underweight, and wasting analysis and 215 593 children (mean [SD] age, 32.63 [15.47] months; 112 259 [52.07%] boys) from 3941 ACs in the anemia analysis. The burden of child undernutrition varied substantially across ACs: from 18.02% to 60.94% for stunting, with a median (IQR) of 35.56% (29.82%-42.42%); from 10.40% to 63.24% for underweight, with a median (IQR) of 32.82% (25.50%-40.96%); from 5.56% to 39.91% for wasting, with a median (IQR) of 19.91% (15.70%-24.27%); and from 18.63% to 83.05% for anemia, with a median (IQR) of 55.74% (48.41%-63.01%). The degree of inequality within states varied across states; those with high stunting, underweight, and wasting prevalence tended to have high levels of inequality. For example, Uttar Pradesh, Jharkhand, and Karnataka had high mean AC-level prevalence of child stunting (Uttar Pradesh, 45.29%; Jharkhand, 43.76%; Karnataka, 39.77%) and also large SDs (Uttar Pradesh, 6.90; Jharkhand, 6.02; Karnataka, 6.72). The Moran I indices ranged from 0.25 to 0.80, indicating varying levels of spatial autocorrelation in child undernutrition across the states in India. No substantial difference in AC-level child undernutrition prevalence was found after adjusting for possible random displacement of geographic location data.

CONCLUSIONS AND RELEVANCE

In this cross-sectional study, substantial inequality in child undernutrition was found across ACs in India, suggesting the importance of considering local electoral units in designing targeted interventions. The methods presented in this paper can be further applied to measuring health and development indicators in small electoral units for enhanced geographic precision of public health data in developing countries.

Can changes in education alter future population ageing in Asia and Europe?

While population ageing is rising, the educational composition of the elderly remains rather heterogeneous. This study assesses the educational differences in future population ageing in Asia and Europe, and how future population ageing in Asia and Europe would change if the educational composition of its populations changed. A comparative population ageing measure (the Comparative Prospective Old-Age Threshold [CPOAT]) was used, which recalculates old-age thresholds after accounting for differences in life expectancy, and the likelihood of adults surviving to higher ages. Combined data from projected age- and sex-specific life-tables (from the United Nations) and projected age- and sex-specific survival ratios by different levels of education (from the Wittgenstein Centre for Demography and Global Human Capital) were used to construct projected life-tables (2015-2020, …, 2045-2050) by educational level and sex for different regions of Asia and Europe. Based on these life-tables, future comparative prospective old-age thresholds by educational level and sex were calculated. It was found that in both Asia and Europe, and among both men and women, the projected old-age thresholds are higher for higher educated people than for less-educated people. While Europe has a larger projected share of elderly in the population than Asia, Europe's older population is better educated. In alternative future scenarios in which populations hypothetically have higher levels of education, the projected shares of elderly in the population decrease across all regions of Asia and Europe, but more so in Asia. The results highlight the effectiveness of investing in education as a policy response to the challenges associated with population ageing in Asia and Europe. Such investments are more effective in the Asian regions, where the educational infrastructure is less developed.

Factors Influencing the Sex Ratio at Birth in India: A New Analysis based on Births Occurring between 2005 and 2016

Previous research on sex ratio at birth (SRB) in India has largely relied on macro-analysis of census data that do not contain the breadth of factors needed to explain patterns in SRB. Additionally, no previous research has examined the differentiation of factors associated with SRB across birth orders, a key determinant in societies affected by son preference. This study aims to fill these gaps using micro-data related to 553,461 births occurring between 2005 and 2016 collected as part of the 2015-2016 National Family Health Survey. Analyses used multivariable logistic regressions stratified by birth order to examine associations with SRB at the national level. The SRB at birth order 1 was outside the biological normal limit, and generally increased with birth order. First births in households with wealth in the middle and richest quintiles, with mothers who desired a higher ideal number of sons than daughters, and in lower fertility communities had a higher probability of being male. Most SRB correlates were visible at birth orders 3 or higher. Programs and policies designed to address India's male-skewed SRB must consider the diverse factors that influence SRB, particularly for higher order births.

Sex differences in child health and healthcare: A reappraisal for India

India has an unenviable reputation as one of the world's most gender disparate countries. Previous studies of sex bias in childhood have shown large differences between Indian boys and girls in immunization and curative healthcare, but little difference in health status as indicated by anaemia and stunting. India has changed rapidly in past decades, hence we reappraise the situation with the National Family Health Survey-4 (2015-16). We found no evidence of sex differentials in immunization coverage but a small degree of discrimination in favour of boys in medical treatment for common symptoms of infection. This discrimination was no greater in the North and Central regions of India, where severe excess mortality among female children persists. Sex differences in anaemia and stunting were small, with no regional pattern. We found no evidence that healthcare or health status of girls was influenced by the presence of other daughters in the family.

Road to family planning and RMNCHN related SDGs: Tracing the role of public health spending in India

Globally, public health expenditure (PHE) is closely associated with Reproductive, Maternal, Newborn, Child Health, and Nutrition (RMNCHN) and Family Planning (FP) outcomes. In India, the role of PHE in shaping the progress towards the attainment of RMNCHN and FP-related Sustainable Development Goals (SDGs) is not widely documented. Using the four consecutive rounds of National Family Health Survey (NFHS), we have investigated the progress in RMNCHN and FP indicators and their association with PHE by applying robust econometric modelling. The findings suggest that although there is noticeable progress in the RMNCHN indicators from 1992-93-2015-16, India has failed to achieve RMNCHN targets related to Millennium Development Goals (MDGs). Lack of noteworthy correlation between FP indicators and PHE supports the argument that post National Rural Health Mission (2005), the core family welfare expenditure suffered a setback despite the absolute rise in PHE. However, correlation plots and the multivariate panel data regression analyses affirm that even with a moderate rise, PHE emerges as an important predictor of RMNCHN outcomes in the country. Thus, the road to achieving RMNCHN and FP-related SDGs demands to avoid austerity on PHE and strengthen the integration of RMNCHN and FP programmes at the operational level.

Perplexing condition of child full immunisation in economically better off Gujarat in India: An assessment of associated factors

BACKGROUND

Despite decent progress in Children Full Immunisation (CFI) in India during the last decade, surprisingly, Gujarat, an economically more developed state, had the second-lowest coverage of CFI (50%) in the country, lower than economically less developed states such as Bihar (62%). Further, the proportion of children with no immunisation in Gujarat has risen from 5% in 2005 to 9% in 2016. This paper investigated factors associated with the low level of CFI coverage in Gujarat.

METHODS

The study used two types of datasets: (1) the information on immunisation from 7730 children aged 12-23 months and their mothers from the fourth round of the Gujarat chapter of National Family Health Survey (NFHS 2015-16). (2) A macro (district) level data on both supply and demand-side factors of CFI are compiled from multiple sources. Bivariate and multivariate linear and logistic regression techniques were employed to identify the factors associated with CFI coverage.

RESULTS

In Gujarat, during 2015-2016, 50% of children aged 12-23 months did not receive full immunisation. The odds of receiving CFI was higher among children whose mothers had a Maternal and Child Protection (MCP) card (OR: 1.97, 95% CI 1.48-2.60) and those who received "high" maternal health services utilisation (OR: 1.59, 95% CI 1.10-2.26) compared to their counterparts. The odds of receiving CFI was about three times higher among the richest households (OR: 6.50, 95% CI 3.75-11.55) compared to their counterparts in the poorer households. Macro-level analyses suggest that poverty, maternal health care, and higher-order births are defining factors of CFI coverage in Gujarat.

CONCLUSIONS

In order of importance, focusing on poverty, economic inequalities, pregnancy registration, and maternal health care services utilisation are likely to improve receiving CFI uptake in Gujarat. The disadvantageous position of urban areas and non-scheduled tribes in CFI coverage needs further investigation.

Gender bias in hospitalization financing from borrowings, selling of assets, contribution from relatives or friends in India

Background

Studies from India have documented gender differentials in hospitalization financing. Much of this work focused either on children or adults, but not across age-groups. No research to date has focused on gender differentials in case of catastrophic hospitalization expenditures. This study assesses gender differentials in distressed financing (borrowing, selling of assets, contributions from relatives or friends) for hospitalization in cases of catastrophic expenditures for hospitalization in India, for young, adult and older adult patients.

Methods

We conducted a cross-sectional analysis of India’s 2017-18 National Sample Survey, which collected data on hospitalization and expenditures. We used multivariable probit regression and adjusted marginal effects to assess the associations between gender and the use of distressed financing for catastrophic hospitalization expenditures. Models were stratified by age, and run both with and without sample selection. Secondary analyses assessed gender differentials in the use of distressed financing for hospitalization in case of health insurance cover or not.

Results

Multivariable sample selection-adjusted probit regression shows that in households which incurred severe catastrophic hospitalization expenditures, the probability of using distressed financing for hospitalization of young or older females was 10% points lower than their male counterparts. In households which did not incur severe catastrophic hospitalization expenditures, there was no significant gender differential in use of distressed financing for hospitalization for any age group. In households which incurred severe catastrophic hospitalization expenditures, the probability of using distressed financing for hospitalization was lower for older females than for older males irrespective of health insurance cover.

Conclusion

There appears to be a clear gender discrimination in distressed financing of hospitalization costs among younger and older individuals in households that incurred severe catastrophic hospitalization expenditures in India. Health systems should consider how to otherwise support necessary hospitalization financing for girls and older women.

•

Young and older females experience bias in hospitalization financing.

•

Biases were concentrated in severe catastrophic hospitalization expenditures.

•

Health insurance did not protect older females against this gender bias.

Comparison of Population Aging in Europe and Asia Using a Time-Consistent and Comparative Aging Measure

Objective: We compare population aging in Europe and Asia using a measure that is both consistent over time and appropriate for cross-country comparison. Method: Sanderson and Scherbov proposed to estimate the old-age threshold by the age at which the remaining life expectancy (RLE) equals 15 years. We propose an adjustment of this measure, taking into account cross-national differences in the exceptionality of reaching that age. Results: Our old-age threshold was lower than 65 years in 2012 in Central Asia, Southern Asia, Southeastern Asia, and many Eastern European countries. These populations also experienced a higher share of elderly compared with the RLE15 method. Our method revealed more geographical diversity in the shares of elderly. Both methods exhibited similar time trends for the old-age thresholds and the shares of elderly. Discussion: Our prospective and comparative measure reveals higher population aging estimates in most Asian and Eastern European countries and more diversity in aging.

A multi-dimensional measure of population ageing accounting for Quantum and Quality in life years: An application of selected countries in Europe and Asia

Population ageing measured through a fixed old-age threshold like 60+ or 65+ ignores the other important dimensions of ageing. There has been changes among the older persons in multiple dimensions that corresponds to quantity of life years lived as well as the quality of life. The existing multi-dimensional measures also consider the characteristics within a fixed old-age threshold framework which does not account for significant improvements in life expectancy over the years. We propose a new Multidimensional Old Age Threshold (MOAT) measure that accommodates different dimensions of quantity and quality of older persons. We achieve this through a modified framework of the Characteristic Approach. Our measure incorporates a forward-looking approach to measure ageing and specifies an old-age threshold for different countries after accounting for different dimensions of life expectancy, health and human capital. This method is more suitable for comparison across countries with distinct demographic and health achievements. The empirical application of our method using selected countries from Europe and Asia shows that the relative performance of countries differs in terms of MOAT in comparison to estimates based on existing measures, primarily due to the inclusion of the quality dimensions. Countries that have better performance in life expectancy, health and human capital have higher values of MOAT and a lower 'burden' of older persons in a cross-country perspective in comparison to the existing measures.

Marital status, widowhood duration, gender and health outcomes: a cross-sectional study among older adults in India

BACKGROUND

Previous research has demonstrated health benefits of marriage and the potential for worse outcomes during widowhood in some populations. However, few studies have assessed the relevance of widowhood and widowhood duration to a variety of health-related outcomes and chronic diseases among older adults in India, and even fewer have examined these relationships stratified by gender.

METHODS

Using a cross-sectional representative sample of 9,615 adults aged 60 years or older from 7 states in diverse regions of India, we examine the relationship between widowhood and self-rated health, psychological distress, cognitive ability, and four chronic diseases before and after adjusting for demographic characteristics, socioeconomic status, living with children, and rural-urban location for men and women, separately. We then assess these associations when widowhood accounts for duration.

RESULTS

Being widowed as opposed to married was associated with worse health outcomes for women after adjusting for other explanatory factors. Widowhood in general was not associated with any outcomes for men except for cognitive ability, though men who were widowed within 0-4 years were at greater risk for diabetes compared to married men. Moreover, recently widowed women and women who were widowed long-term were more likely to experience psychological distress, worse self-rated health, and hypertension, even after adjusting for other explanatory variables, whereas women widowed 5-9 years were not, compared to married women.

CONCLUSIONS

Gender, the duration of widowhood, and type of outcome are each relevant pieces of information when assessing the potential for widowhood to negatively impact health. Future research should explore how the mechanisms linking widowhood to health vary over the course of widowhood. Incorporating information about marital relationships into the design of intervention programs may help better target potential beneficiaries among older adults in India.

Abuse against elderly in India--the role of education

Background

Abuse against the elderly is recognized as an important challenge to elderly health, but its determinants are not yet well understood. We present findings from a new dataset which covers a representative sample of the population aged 60 years and above from seven Indian states across India – all of which have a higher proportion aged 60 plus compared to the national average. Earlier studies suggest that schooling levels can be relevant in determining the level of abuse against seniors. This study focuses on the role of education on the prevalence of elderly abuse in India.

Methods

We conduct an analysis of cross sectional primary data that contains information on elderly abuse. The households in the sample were randomly selected from the seven demographically oldest states in India. These states are Himachal Pradesh, Kerala, Maharashtra, Odisha, Punjab, Tamil Nadu and West Bengal. A total of 9852 elderly from 8329 households were interviewed. The statistical analysis is based on logistic regression to understand the independent relation of education with abuse against the elderly.

Results

Our findings reveal that 11% of 60+ year olds have experienced at least one type of elderly abuse (Physical 5.3%, Verbal 10.2%, Economic 5.4%, Disrespect 6%, Neglect 5.2%). The most common perpetrator is the son, who is reported to be responsible for the abuse among 41% of male victims and 43% of female victims. Formal education among elderly beyond a certain level (8 years) has a strong relation with reduced violence against elderly.

Conclusions

Our findings suggest that level of schooling among elderly is strongly negatively related to abuse against them. More members in the household reduces the chance of abuse while having a greater number of children increases the chance of abuse (neglect and verbal abuse). We find that education even after controlling for wealth and other relevant variables is the factor that most consistently lowers elderly abuse. However, the relation of education to abuse is limited to those with more than 8 years of schooling. This suggests that the ongoing educational expansion beyond the basic schooling years in India may lead to a decline in the incidence of elderly abuse.

India's demographic change: opportunities and challenges

This paper discusses emerging demographic patterns and its opportunities and challenges for India. It investigates the specificities in the demographic transition in terms of various demographic parameters and the lack of homogeneity in the transition across states in the country. It presents some opportunities that can arise from having demographic changes, particularly the demographic dividend and interstate migration to overcome labor shortage in some parts. At the same time, there are serious challenges in the form of enhancing human capital development, addressing the issue of skewed sex ratio, and the possible rise in social and political unrest and conflict.

Safe use of remifentanil in a patient treated with the monoamine oxidase inhibitor phenelzine

We report the safe use of remifentanil as part of the anaesthetic technique in a patient undergoing major head and neck surgery who was being treated for depressive illness with the non-specific monoamine oxidase inhibitor (MAOI) phenelzine.

Glycopyrrolate reduces nausea during spinal anaesthesia for caesarean section without affecting neonatal outcome

We have tested the hypotheses that glycopyrrolate, administered immediately before induction of subarachnoid anaesthesia for elective Caesarean section, reduces the incidence and severity of nausea, with no adverse effects on neonatal Apgar scores, in a double-blind, randomized, controlled study. Fifty women received either glycopyrrolate 200 micrograms or saline (placebo) i.v. during fluid preload, before induction of spinal anaesthesia with 2.5 ml of 0.5% isobaric bupivacaine. Patients were questioned directly regarding nausea at 3-min intervals throughout operation and asked to report symptoms as they arose. The severity of nausea was assessed using a verbal scoring system and was treated with increments of i.v. ephedrine and fluids. Patients in the group pretreated with glycopyrrolate reported a reduction in the frequency (P = 0.02) and severity (P = 0.03) of nausea. Glycopyrrolate also reduced the severity of hypotension, as evidenced by reduced ephedrine requirements (P = 0.02). There were no differences in neonatal Apgar scores between groups.

Comparison of epidural bolus administration of 0.25% bupivacaine and 0.1% bupivacaine with 0.0002% fentanyl for analgesia during labour

We have compared analgesia during labour provided by two epidural drug regimens, in a double-blind, randomized, controlled study. Group A received 10-ml bolus doses of 0.1% bupivacaine with fentanyl 2 micrograms ml-1 while group B received 0.25% plain bupivacaine 10 ml. Analgesia provided by both techniques was similar, but women in group A retained motor power in their legs and 60% chose to get out of bed. Duration of labour and time from insertion of the epidural to delivery was similar in both groups, but in group A, duration of the second stage was significantly shorter (P = 0.0003; 95% confidence interval (CI) -1.17, -0.27 h) and the incidence of forceps delivery was lower (P = 0.032). Maternal satisfaction with epidural analgesia, as assessed by VAS, was higher in group A (P = 0.04; 95% CI -0.001, 10.001).

Combined spinal-extradural anaesthesia for preterm and term caesarean section: is there a difference in local anaesthetic requirements?

In a non-blinded observational study, we have tested the null hypothesis that there is no difference in local anaesthetic requirements for subarachnoid anaesthesia between women presenting for Caesarean section at term or preterm (38-42 and 28-35 weeks' gestation, respectively). Using a combined spinal-extradural technique, 2.25 ml of 0.5% hyperbaric bupivacaine was given, in the sitting position, to 50 women presenting for Caesarean section. In 21 of 25 preterm women, adequate sensory block for surgery did not develop (P < 0.001) and they required supplementary extradural local anaesthetic (median 8 ml of 2% lignocaine with 1:200,000 adrenaline (interquartile range 4-12 ml)); preterm women not requiring extradural supplementation were at the upper end of the gestational range. There was a strong linear correlation between increasing gestation and block height in the preterm group (Spearman rank correlation coefficient = 0.74; 95% confidence intervals 0.49, 0.88). All women in the term group developed adequate anaesthesia with the subarachnoid dose alone. Onset of anaesthesia was slower in the preterm group (median 15 vs 5 min) with a lower incidence of hypotension (P = 0.0005).

Patient-controlled analgesia following caesarean section: a comparison of morphine and meptazinol

Forty-eight women were investigated in a prospective double-blind study and randomised to receive intravenous patient-controlled analgesia (PCA) with meptazinol or morphine following elective caesarean section. Women received PCA boluses of 1 mg morphine or 10 mg meptazinol with no background infusion. Total drug consumption measured over a 24 h period, pain (visual analogue scores), sedation scores, incidence of nausea and vomiting, and requests for rescue analgesia were compared. Both meptazinol and morphine delivered via PCA provide satisfactory analgesia after caesarean section. There was no statistically significant difference in pain scores (P = 0.47) or the incidence of side-effects (nausea/vomiting P = 0.076, sedation P = 0.63) between the two drugs. Meptazinol is more expensive and offers no clinical advantages in this group of patients.

Spinal anaesthesia for Caesarean section: effect of Sprotte needle orientation

We induced spinal anaesthesia in 100 women presenting for elective Caesarean section with the mother in the right lateral position. Patients were allocated randomly to have the side eye of the 24-gauge Sprotte spinal needle pointing in one of four directions: group A, cephalad; group B, right lateral; group C, left lateral; group D, caudad. Isobaric bupivacaine 0.5% (2.5 ml) was injected over 30 s before the mother was placed supine with a 15 degree left lateral tilt. Onset time and height of the subsequent analgesic and anaesthetic blocks were assessed by a blinded observer. Onset of sensory block to T4 was significantly faster in group A (P = 0.001). There were no differences in final block height, incidence of hypotension, nausea and vomiting or ephedrine requirements.

Canine bone response to tyrosine-derived polycarbonates and poly(L-lactic acid)

Tyrosine-derived polycarbonates are a new class of degradable polymers developed for orthopedic applications. In this study the long-term (48 week) in vivo degradation kinetics and host bone response to poly(DTE carbonate) and poly(DTH carbonate) were investigated using a canine bone chamber model. Poly(L-lactic acid) (PLA) served as a control material. Two chambers of each test material were retrieved at 6-, 12-, 24-, and 48-week time points. Tyrosine-derived polycarbonates were found to exhibit degradation kinetics comparable to PLA. Each test material lost approximately 50% of its initial molecular weight (Mw) over the 48-week test period. Poly(DTE carbonate) and poly(DTH carbonate) test chambers were characterized by sustained bone ingrowth throughout the 48 weeks. In contrast, bone ingrowth into the PLA chambers peaked at 24 weeks and dropped by half at the 48-week time point. A fibrous tissue layer was found surrounding the PLA implants at all time points. This fibrous tissue layer was notably absent at the interface between bone and the tyrosine-derived polycarbonates. Histologic sections revealed intimate contact between bone and tyrosine-derived polycarbonates. From a degradation-biocompatibility perspective, the tyrosine-derived polycarbonates appear to be comparable, if not superior, to PLA in this canine bone chamber model.

Influence of dose and timing of administration of morphine on postoperative pain and analgesic requirements

In a randomized, double-blind study, we have investigated the effect of dose and timing of administration of morphine on postoperative pain and analgesic requirements in 60 patients undergoing hysterectomy, with or without salpingo-oophorectomy. Patients were allocated randomly to one of three groups: during standardized general anaesthesia, group post received morphine 0.15 mg kg-1 i.v. at peritoneal closure after hysterectomy; group pre-low received morphine 0.15 mg kg-1 on induction of anaesthesia; and group pre-high received morphine 0.3 mg kg-1 on induction of anaesthesia. Median postoperative morphine consumption (first 24 h) from a PCA system was 68 mg (group post), 56 mg (group pre-low) and 43 mg (group pre-high), and total perioperative morphine consumption (induction of anaesthesia to end of 24 h after surgery) was 77 mg (group post), 65 mg (group pre-low) and 63 mg (group pre-high). Pain scores (at rest and on movement) were similar in the three groups. A large dose of morphine 0.3 mg kg-1 i.v. on induction of anaesthesia significantly reduced postoperative PCA morphine requirements compared with the smaller dose (0.15 mg kg-1) administered at induction or peritoneal closure, in patients undergoing hysterectomy, with or without salpingo-oophorectomy.

Biomechanical evaluation of the stability of thoracolumbar burst fractures

STUDY DESIGN

The decision to treat thoracolumbar burst fractures in neurologically intact patients either surgically or nonoperatively depends largely on whether the fracture is clinically stable. This study evaluated the relative contributions of the anterior, middle, and posterior columns to spinal stability by way of in vitro experimentation and supplemental analysis of patients with nonoperatively treated burst fractures.

METHODS

An L1 burst fracture model was used to evaluate the contribution of the three columns of the spine to resisting imposed flexion deforming forces. Six spines were tested to a gross bending flexion angle of 25 degrees. Changes in vertebral motion across the site of injury were measured and compared. In addition, a summary of our recent clinical experience with nonoperatively treated burst fractures is presented and correlated with the study's laboratory findings.

RESULTS

T12-L2 motion measurements after vertebral and ligamentous disruption revealed a statistically significant increase in motion upon anterior and added posterior column compromise, but not for added middle column disruption. Review of the clinical series revealed that burst fractures with anterior and middle column compromise but an intact posterior column were stable and healed satisfactorily.

CONCLUSIONS

The data suggest that the condition of the posterior column, not the middle column, is a better indicator of burst fracture stability. It is proposed that the classic burst fracture (anterior and middle column compromise) is a stable injury that, in the absence of neurologic deficit, can be managed nonoperatively.

Distraction and compression loads enhance spine torsional stiffness

We have assessed the degree to which compression and distraction forces applied to the spine of the magnitude achievable through instrumentation systems increase torsional stiffness, thereby possibly enhancing the environment for arthrodesis. A functional relationship between spine torsional stiffness and axial compression and distraction forces is described. To establish this relationship whole human thoracolumbar spines as well as individual motion segments were tested in torsion under a variety of axial loading conditions consistent with forces applied clinically. These studies indicate that applying axial loads to the whole thoracolumbar spine through the action of compression or distraction increases the stiffness of the spine in torsion. Compression and distraction forces increased the torsional stiffness of thoracic segments, but only compression forces were found to significantly increase the stiffness of lumbar segments. The soft tissue structures of both the anterior and the posterior columns have the ability to increase torsional stiffness with axial loading.

Effects of a fish oil supplement on serum lipids, blood pressure, bleeding time, haemostatic and rheological variables. A double blind randomised controlled trial in healthy volunteers

Sixty male volunteers were randomised to take 10-16 ml of a fish oil supplement (MaxEPA) or 10-16 ml of olive oil for a period of 3-6 weeks. A fall in serum triglyceride of 54% (P less than 0.01) and a fall in diastolic blood pressure of 7% (P less than 0.05) was attributable to taking fish oil supplements. The bleeding time was prolonged by 12%, but this did not reach conventional levels of statistical significance. A global test of heparin-neutralising activity, the heparin thrombin clotting time, increased by 14% (P = 0.05) but there was no demonstrable effect on thrombin time, fibrinogen or (intraplatelet) platelet factor 4. A fall in red cell pore transit time of 23% was attributable to fish oil, but was not statistically significant. There was no convincing evidence of an effect of fish oil supplementation on total serum cholesterol, HDL-cholesterol, blood counts or platelet aggregation. A beneficial effect of fish oil on the cardiovascular risk profile was confirmed in this study. However, with this regime changes in total cholesterol, HDL-cholesterol and platelet aggregation are of unlikely clinical importance.
