Adolescent birth and child undernutrition: an analysis of demographic and health surveys in Bangladesh, 1996-2017

Association of child marriage and nutritional status of mothers and their under-five children in Bangladesh: a cross-sectional study with a nationally representative sample

BACKGROUND

Child marriage remains an important problem around the world with young mothers and their under-five children often experiencing under-nutrition. The problem is rarely studied in the Bangladeshi population. This paper was designed to identify the association between child marriage and nutritional status of mothers and their under-five children in Bangladesh.

METHODS

Nationally representative secondary data was used for this study, data was extracted from the Bangladesh Demographic and Health Survey (BDHS) 2017-18. The sample consisted of 7235 mothers aged 18-49 years and their under-five children. The mothers were classified into two classes according to their age at first marriage: (i) child marriage (marriage at < 18 years) and (ii) not child marriage (marriage at ≥ 18 years). The nutritional status of mothers was measured by body mass index (BMI), and under-five children's nutritional status was measured by (i) height-for-age (z-score) (stunting), (ii) weight-for-age (z-score) (underweight), and (iii) weight-for-height (z-score) (wasting). The chi-square test and two-level logistic regression model were used for data analysis using SPSS software (IBM version 20).

RESULTS

The prevalence of child marriage among Bangladeshi women was 69.0%, with the mean and median of age at the first marriage being 16.57 ± 2.83 years and 16 years, respectively. Of the mothers, 15.2% suffered from chronic energy deficiency (underweight), and 72.8% were married at < 18 years. The prevalence of stunting, underweight, and wasting among under-five children in Bangladesh was 31.0%, 22.0%, and 8.5%, respectively. Compared to women married at the age of ≥ 18 years, there was a significantly higher likelihood of chronic energy deficiency among women who married at < 18 years [Adjusted OR = 1.27, CI: 1.05-1.82; p < 0.05]. Under-five children of mothers married before the age of 18 were more likely to have stunting [Adjusted OR = 1.201, CI: 1.11-1.72; p < 0.05], wasting [Adjusted OR = 1.519, CI: 1.15-2.00; p < 0.01], and underweight [Adjusted OR = 1.150, CI: 1.09-1.82; p < 0.05] compared to children of mothers who married at age ≥ 18.

CONCLUSION

The rate of child marriage among Bangladeshi women is high, and it is significantly associated with malnutrition among mothers and their under-five children. The Bangladesh government can use the findings of this study to prevent and reduce child marriage and malnutrition among mothers and their under-five children to achieve sustainable development goals by 2030.

Stagnation of maternal mortality decline in Bangladesh between 2010 and 2016 in spite of an increase in health services utilisation: Examining data from three large cross-sectional surveys

Background

After a 40% reduction in maternal mortality ratio (MMR) during 2001-2010 in Bangladesh, the MMR level stagnated between 2010 and 2016 despite a steady increase in maternal health services use and improvements in overall socioeconomic status. We revisited the factors that contributed to MMR decline during 2001-2010 and examined the changes in these factors between 2010 and 2016 to explain the MMR stagnation in Bangladesh.

Methods

We used data from the 2001, 2010, and 2016 Bangladesh Maternal Mortality Surveys, which sampled 566 115 households in total, to estimate the changes in the risk of dying of maternal causes associated with a pregnancy or birth between 2001-2010 and 2010-2016. We carried out Poisson regression analyses with random effects at the sub-district level to explore the relationship between the change in risk of maternal death from 2001 to 2016 and a range of demographic, socioeconomic, and health care factors.

Results

Between 2001 and 2016, the proportion of high-risk pregnancies decreased, except for teenage pregnancies. Meanwhile, there were notable improvements in socioeconomic status, access to health services, and the utilisation of maternal health services. A comparison of factors affecting the risk of maternal death between 2001-2010 and 2010-2016 indicated that first pregnancies continued to offer significant protection against maternal deaths. However, subsequent pregnancies among girls under 20 years became a significant risk factor during 2010-2016, increasing the risk of maternal deaths by nearly 3-fold. Among the key maternal health services, only skilled birth attendants (SBA) were identified as a key contributor to MMR reduction during 2001-2010. However, SBA is no longer significantly associated with reducing mortality risk during 2010-2016.

Conclusions

Despite continued improvements in the overall socioeconomic status and access to maternal health services in Bangladesh, the stagnation of MMR decline between 2010 and 2016 is associated with multiple teenage pregnancies and the lack of capacity in health facilities to provide quality delivery services, as SBA has been primarily driven by facility delivery. The findings provide a strong rationale for targeting at-risk mothers and strengthening reproductive health services, including family planning, to further reduce maternal mortality in Bangladesh.

Adolescent pregnancy is associated with child undernutrition: Systematic review and meta-analysis

Adolescent pregnancy is associated with poor fetal growth and development which, in turn, increases the risk of childhood wasting and underweight. However, evidence on how young maternal age affects childhood anthropometry beyond the neonatal period is limited. This systematic review and meta-analysis examined associations between adolescent pregnancy and child wasting and underweight and explored potential underlying social and biological factors. Peer-reviewed literature published in English since 1990 was systematically searched. Eligible studies presented data on wasting and/or underweight in children (≤59 months) born to adolescent mothers (10-19, or ≤24 years where applicable) from low- and middle-income countries. Data extraction used a predefined extraction sheet. Both meta-analysis and qualitative synthesis were performed. Of 92 identified studies, 57 were included in the meta-analysis. The meta-analysis showed that children born to adolescent versus adult mothers were at a higher risk of moderate (odds ratio [OR]: 1.12, 95% confidence interval [CI]: 1.00-1.26 p = 0.04) and severe underweight (OR: 1.21, 95% CI: 1.08-1.35 p < 0.01). Associated risk of wasting was not statistically significant: (OR: 1.05, 95% CI: 0.98-1.12 p = 0.17); severe wasting (OR: 1.16, 95% CI: 0.68-1.96 p = 0.59). These findings were supported by the qualitative synthesis. Evidence on the potential role of biological/social factors was limited, but suggested an intermediary role of maternal nutritional status which warrants further exploration. Particularly in contexts where adolescent pregnancy remains common, interventions to both delay adolescent pregnancy and improve adolescent nutritional status could help reduce the risk of undernutrition in children and contribute to breaking the intergenerational cycle of malnutrition.
