Association of Parental Height With Offspring Stunting in 14 Low- and Middle-Income Countries

Growth patterns of preterm and small for gestational age children during the first 10 years of life

Background

Preterm and small for gestational age (SGA) remain significant public health concerns worldwide. Yet limited evidence exists on their growth patterns during childhood from low-or middle-income countries.

Objectives

We investigated the postnatal growth patterns of preterm and SGA compared to term appropriate for gestational age (AGA) children from birth to 10-11y, and examined the impact of birth status on child nutritional status during the school age years.

Methods

Children born to women who participated in a double-blinded randomized controlled trial of preconception micronutrient supplementation in Vietnam were classified into three groups: preterm AGA (n = 130), full-term SGA (n = 165) and full-term AGA (n = 1,072). Anthropometric data (weight and height) were collected prospectively at birth, 3, 6, 12, 18, 24 months and at 6-7 and 10-11y. We used ANOVA and multiple regression models to examine the differences in growth patterns from birth to 10-11y as well as child undernutrition and overnutrition by birth status.

Results

Children who were born preterm exhibited rapid postnatal growth, but still had lower HAZ at 1y and 2y and showed catch up to the AGA group at 6y. Compared to those born AGA, SGA infants had higher risk of thinness (BMIZ < -2) at 2y and 6y (adjusted Odds Ratio, AOR [95% CI] 2.5 [1.0, 6.1] and 2.6 [1.4, 4.6], respectively); this risk reduced at 10-11y (1.6 [0.9, 2.8]). The risk of stunting (HAZ < -2) was also 2.4 [1.5, 3.8] and 2.3 times [1.2, 4.1] higher in SGA than AGA group at ages 2y and 6-7y, respectively, with no differences at 10y. Although preterm children had higher rates of thinness and stunting at 2y compared to AGA children, these differences were not statistically significant. No associations were found between preterm or SGA and overweight /obesity at age 10-11y.

Conclusion

Children who were born term-SGA continued to demonstrate deficits in weight and height during childhood whereas those born preterm showed catch-up growth by age 6-7y. Additional efforts to reduce the burden of these conditions are needed, particularly during school-age and early adolescents when children are exposed to challenging environments and have higher demands for nutrition.

Influence of parental anthropometry and gestational weight gain on intrauterine growth and neonatal outcomes: Findings from the MAI cohort study in rural India

Poor foetal growth and subsequent low birth weight are associated with an increased risk for disease later in life. Identifying parental factors that determine foetal growth are important to curbing intergenerational malnutrition, especially among disadvantaged populations in the global south where undernutrition rates are high. The objective of this study was to assess the relationships between parental biometry, intrauterine growth and neonatal outcomes, while factoring in socioeconomic status of historically disadvantaged households in rural India. Using data from the prospective longitudinal cohort, pregnant women from rural Pune, India (n = 134) were assessed between August 2020 and November 2022. Data on socio-demography, ultrasound measurements, parental and foetal anthropometry were collected. Multiple linear regression models were run to predict determinants of foetal intrauterine and neonatal growth (p value<0.05). The dependent variables were ultrasound measurements and neonatal biometry, and independent variables were gestational weight gain, parental and mid-parental height. Mean(±SD) maternal age, maternal height, paternal height and mid-parental height were 22.8±3.7 years, 153.6±5.5cm, 165.9±6.5cm and 159.1±8.7cm, respectively. Pre-pregnancy body mass index and gestational weight gain was 20.5±4.0 kg/m2 and 9.8±3.7kg respectively. Mid-parental height and gestational weight gain were strongly correlated with neonatal growth and foetal intrauterine growth (p<0.05); however, the correlation peaked at 28 weeks of gestation (p<0.05). Gestational weight gain (B = 28.7, p = 0.001) and mid-parental height (B = 14.3, p = 0.001) were identified as strong determinants of foetal-intrauterine growth and neonatal anthropometry at birth. Maternal height was found to influence length of male neonate (B = 0.18, p = 0.001), whereas, paternal height influenced length of the female neonate (B = 0.11, p = 0.01). Parental socio-economic status, biometry and maternal gestational weight gain influence growth of the child starting from the intrauterine period. Our study underlines the need for interventions during pre-pregnancy, as well as during pregnancy, for optimal weight gain and improved foetal and neonatal outcomes.

Determinants of Stunting Children Under Five of Age During the COVID-19 in the Working Area of the Liwuto-Primary Public Health Center, Baubau City-Indonesia: A Community-Based Unmatched Case–Control Study

BACKGROUND: In Indonesia, the stunting prevalence has reached 24.4% in 2021. AIM: The study aims to examine the determinants of stunting among children under five of age during the COVID-19 pandemic in the working area of the Liwuto-Primary Public Health Center, Baubau city. METHODS: A community-based unmatched case–control study was conducted from January 10, to March 10, 2022, on a sample of 94, cases (n = 21), and controls (n = 73) of children aged 0–59 months with their respective mothers. Data were collected using a face-to-face interviewer-administered questionnaire and physical measurements standard. The data were analyzed using SPSS version 17. The variables were entered into the multivariable model using the backward stepwise regression approach. Multivariable logistic regression analysis was used to identify factors associated with stunting. Adjusted odds ratio (AOR) with a 95% confidence interval (95% CI) and p < 0.05 was used to declare the significance. RESULTS: There are 22% of the stunting become in children under 5 years. Stunting children under 5 years was associated with maternal age (AOR = 5.71, 95%, CI: 1.91–17.03). While family income (AOR = 1.78, 95%, CI: 0.17–18.86), exclusive breastfeeding (AOR = 3.95, 95%, CI: 0.14–112.72), complementary feeding (AOR = 1.24, 95%, CI: 0.18–8.55), formal education (AOR = 0.74, 95%, CI: 0.36–1.53), and occupation (AOR = 2.98, 95%, CI: 0.24–36.55) were not associated with the stunting. CONCLUSION: Young mother under 30 years old was an important risk factor on the incidence of stunting in children under 5 years during the COVID-19 pandemic.

Maternal Risk Factor on Incidence of Stunting in South Sumatera

BACKGROUND: Stunting is an adverse result condition of unfulfilled nutritional intake during pregnancy and early childhood, which affects the children’s maximum height and optimal cognitive potential. Stunting is influenced by numerous factors, both from the mother and children. Research has proven that factors related to mothers of children under 5 have essential roles in the incidence of stunting. AIM: This study intends to analyze the influence of maternal risk factors on the incidence of stunting in children under 5 in districts/cities in South Sumatra. METHODS: This study is quantitative research with a cross-sectional design, with secondary data sources from Basic Health Research 2018, carried out in 17 districts/cities in South Sumatra. RESULTS: The mothers’ characteristics most significantly related to stunting in children under 5 in the South Sumatra region are the mother’s height and mother’s education. Mothers with a height <150 cm have a 1.547 times higher risk of having stunting children (95% CI: 1.281–1.868), and mothers with low education have a 1.521 times higher risk of having stunting children (95% CI: 1.094–2.116). Moreover, mothers with secondary education are at 1.473 times higher risk of having stunting children (95% CI: 1.073–2.020). CONCLUSION: The maternal risk factors most associated with stunting in children under five in South Sumatra are maternal height and mother’s education.

The Indirect Impact of Smallholder Vegetable Production on Children's Nutrition Outcomes in Rural Vietnam

Childhood undernutrition, particularly stunting, wasting, and micronutrient deficiencies, remains a major health concern in rural Vietnam. While literature suggests leveraging agriculture to improve child nutrition via agricultural diversification, market engagement, and women's empowerment, very few studies have empirically explored how smallholder vegetable production can influence household nutrition. This paper examines the association of household-level vegetable diversity, market access, and market participation with nutrition outcome measures of children in smallholder households. We use a cross-sectional household dataset, collected in 2016 in northwest Vietnam, covering 234 children aged 6–60 months. We estimate and compare the results of regression models using three-stage least squares (3SLS), ordinary least squares (OLS), logistic regression, and seemingly unrelated regression (SUR), to explore variations in six nutrition outcome measures: height-for-age z-score (HAZ), weight-for-height z-score (WHZ), weight-for-age z-score (WAZ), stunting, wasting, and underweight. Our results suggest smallholder vegetable production has a significant indirect association with children's nutrition status via market participation. Market participation is an important factor in improving girls' HAZ and WHZ, and in reducing the probability of boys being stunted and underweight. The additional income from selling vegetables allows households to purchase nutritious food, which is likely to have a positive impact on children's nutrition outcomes.
