The psychological distress of parents is associated with reduced linear growth of children: evidence from a nationwide population survey
AbstractBackgroundStunting, an indicator of restricted linear growth, has become a primary measure of childhood undernutrition due to its persistent high prevalence globally, and importance for health and development. Although the etiology is recognized to be complex, most analyses have focused on biomedical determinants, with limited attention to social factors affecting care and nurturing in the home.ObjectivesTo identify the association between parental distress and linear growth and stunting and to examine z score loss due to any parental distress and socioeconomic, behavioral, and physiologic risk factors on for linear growthDesignCross sectional studyParticipants54,261 households from the Indonesia National Health Survey 2013. Main outcome measures. Multivariate linear, logistic, and multilevel multinomial logistic regression, using survey weights, were used to assess the relationship between parental distress, as assessed by the WHO Self Reporting Questionnaire, with height-for-age z score (HAZ), stunting, and behavioral risk factors for stunting.ResultsMaternal, paternal and parental distress (i.e. both maternal and paternal distress) were associated with reduced linear growth of the children by 0.091, 0.13 and 0.21 z-scores, respectively. Maternal and paternal distress increased the risk of mild stunting (HAZ < -1) by 38% and 39%, and the risk of moderate stunting (HAZ < -2) by 41% and 23%, respectively. Parental stress increased the risk of moderate and severe stunting by 67% and 41%. Any parental distress accounted for 5.6% of the modeled overall loss of HAZ-score due to interactions with socioeconomic status (low maternal occupational status, low wealth, low maternal occupation) and behavioral (poor garbage sanitation) factors, rendering it amongst the more influential factors on linear growth. The modeled overall loss of HAZ-score incorporating any parental distress was associated with socioeconomic factors (26.1%) including, in descending order, low maternal occupational status, low wealth, low maternal education, low paternal occupational status, rural residence; behavioral factors (15.3%) including open garbage disposal, unimproved water disposal, paternal smoking, not using iodized salt; physiological factors (13.5%) including low maternal height, female child, paternal height, maternal mid-upper arm circumference.ConclusionsThese findings highlight the complex etiology of stunting, and suggest nutritional and other biomedical interventions are insufficient, and that promotion of mental and behavioral health programs for parents are essential to achieve child growth and development, and would likely foster taller, healthier, smarter, and thriving populations.
