“…Diverse factors, such as economic inequality, urbanization, migration from rural to urban regions, geographical and sociocultural differences, and food security, all together might have influenced the lifestyle habits of the Mexicans, resulting in these new conditions and a secular trend effect of children’s height ( 66–68 ). It was observed in Mexican children that stature can vary between those living in moderate and extreme poverty and those who are not poor ( 69 ). Socioeconomic status was observed to be associated with stunting conditions, mainly in Mexico, where approximately 40% of children with stunting are estimated to be in the low and very low socioeconomic levels ( 70 ).…”

The present study aimed to estimate the height growth curve for Mexican boys and girls based on their body mass index (BMI) status (normal and overweight/obese) and to develop a height Lambda, Mu, and Sigma (LMS) growth reference for Mexican children aged 2 to 18 years.MethodsChronological age and height records (7,097 boys and 6,167 girls) were obtained from the Mexican National Survey of Health and Nutrition database. Height growth curves were fitted using the Preece-Baines 1 (PB1) model and the LMS method.ResultsAge at peak height velocity (APHV) was 12.4 and 12.7 years for overweight-obese and normal-weight boys, respectively, and was 9.6 and 10.4 years for overweight-obese and normal-weight girls, respectively. Growth velocity was higher at the age of take-off (TO) in overweight-obese children than in normal-weight children (5.2 cm/year vs. 5 cm/year in boys and 6.1 cm/year vs. 5.6 cm/year in girls); nevertheless, the growth velocity at APHV was higher for normal-weight children than for overweight-obese children (7.4 cm/year vs. 6.6 cm/year in boys and 6.8 cm/year vs. 6.6 cm/year in girls, respectively). Distance curves developed in the present study and by the World Health Organization (WHO) using LMS showed similar values for L and S parameters and a higher M value compared with the WHO reference values.ConclusionThis study concluded that overweight-obese children had earlier APHV and lower PHV than normal-weight children. Furthermore, Mexican children and adolescents were shorter than the WHO growth reference by age and sex.

“…The literature suggests important heterogeneity in terms of growth pattern and health outcomes between boys and girls, especially in developing countries (Vilar-Compte et al, 2020). This helps account for the potential gender-specific impacts of unobserved factors (Kong et al, 2019).…”

This paper examines the growth effect of one of the largest nutrition assistance programs in early life. The program covers 5.8 million children in poor ruralChina and provides 6-24-month old children with a free nutrition supplement that contains nine essential micronutrients. We utilize a phase-in procedure by county for identification and estimate its impact on several early-life health indicators.Robust evidence shows that such nutrition supplements effectively increase boys' weight and reduce their probability of being underweight. No effect is observed on girls of similar age. These health indicators are related to long-term human capital development. The gender differences in policy impact that are identified in this paper have important implications for nutrition subsidy in the early years of life in developing countries.

Existing research on human growth in Mexico is regionally focused, creating a gap in the understanding of growth patterns of children and adolescents at national level and regional variation. The objective of the present study was to characterize the height growth curve of the Mexican population by geographic area and to cluster the states of the Mexican Republic according to their somatic maturation characteristics, based on a national representative sample of boys. Data on age, height, socioeconomic level, and geographic area of 18,219 boys were obtained from the National Health and Nutrition Survey 2012 (ENSANUT) and ENSANUT 2018, carried out in 32 Mexican states. Both surveys had representative samples. Preece–Baines 1 model was applied to fit height growth curves. Biological parameters were estimated; principal component analysis and cluster analysis were performed to group Mexican states based on these biological parameters. The estimated age at peak height velocity (PHV) was 12.3 years in the sample. Significant regional differences in the timing and tempo of PHV among Mexican boys were observed. Boys in the northern region experienced PHV at an earlier age and had a shorter duration of growth compared with boys in the central and southern regions. Boys in the central region had a longer duration of growth and a later age of PHV compared with the boys in the southern region. The cluster that included the southern states of the country showed estimated lower adult height and earlier somatic maturation. A lower height was found in the low and low-middle socioeconomic levels compared with the medium-high and high socioeconomic levels. Future research in Mexico should focus on longitudinal studies to analyse the timing and tempo of growth and maturation, considering the impacts of environmental and genetic factors. Public health strategies should account for geographic variations.
