Background: The persistently high prevalence of undernutrition in Cambodia, in particular stunting or chronic malnutrition, calls for innovative investigation into the risk factors that affect children’s growth during critical phases of development. Methods: Secondary data analysis was performed on a subgroup of children who were present at two time points within the Cambodian Health and Nutrition Monitoring Study (CAHENMS) and who were less than 24 months of age at the nominated baseline. Data consisted of parent interviews on sociodemographic characteristics and feeding practices, and clinical measures for anthropometric measures and dental status. Logistic regression modelling was used to examine the associations between severe dental caries (tooth decay)—as indicated by the Significant Caries Index—and the presence of new cases of stunting malnutrition at follow-up. Results: There were 1595 children who met the inclusion criteria and 1307 (81.9%) were followed after one year. At baseline, 14.4% of the children had severe dental caries, 25.6% presented with stunted growth. 17.6% of the children transitioned from healthy status to a low height-for-age over the observation period. Children with severe dental caries had nearly double the risk (OR = 1.8; CI 1.0–3.0) of making that transition. Conclusion: Severe caries experience was associated with poorer childhood growth and, as such, could be an underinvestigated contributor to stunting.
Age-appropriate feeding practice (ADF) during early childhood are vital for optimal nutrition. This longitudinal study determined the effect of selected risk factors and ADF, as described by the National Nutritional Recommendations, on linear and ponderal growth of children below 24 months of age. Weight and length measures were used to calculate z-scores of anthropometric measures by WHO standards. The prevalence of stunting increased from 13.2% to 32.4% over time, while prevalence of wasting remained stable (14.5%). At first visit, 43% of children of all ages complied with ADF criteria, a proportion which decreased to 7.1% in follow-up. The quality of feeding practices for children above 12 months of age was the poorest, where at the last visit, only 6% complied with the criteria for ADF. The linear mixed-effect models found the association between ADF and ponderal growth to be significant (weight-for-height estimate: 0.05 SD). In Cambodia, Ratanakiri province, ADF was the second largest determinant for ponderal growth. We recommend province specific public health actions. For children above 6 months, the quantity of food given needs to be increased, followed by the meal frequency. Mothers’ educational level, improved sanitation, and drinking water quality were among strongest predictors of a child’s growth.
Even though limited evidence is available, the relationship between morbidity and under-nutrition among children under-five is likely to be a strong two-way association. This study aims to explore this vicious cycle by employing longitudinal data of four periods within a 24 month follow-up, whereby morbidity was captured between two subsequent anthropometric measures. Malnutrition was classified according to z-scores of anthropometric measures and morbidity by number of sick days experienced inbetween. Mixed-effects models were used to assess this relation, where dependency of morbidity and nutritional status were interchanged; models were adjusted for province, age, gender, wealth index score, maternal education level, diet, and Water, Sanitation, and Hygiene indicators. Stunting and wasting prevalences were 29.9% and 8.9%, respectively, where 21.3% of the children hadmultiple anthropometric failures. Children identified as wasted were 35% more likely to experience prolonged illness periods (OR: 1.35, 95% CI: 1.02–1.56). Those experiencing high proportion of sick days were found to be 64% more likely to become stunted (OR: 1.64, 95% CI: 1.18–2.29). This study suggests that the link between wasting and stunting could be partly explained by acute illness, where wasting increases the likelihood of prolonged epiosed of illness, which increases the risk of stunting.
Worldwide, over 250 million children under 5 years do not reach their developmental potential due to several causes, including malnutrition. In Cambodia, the prevalence of stunting and wasting among children remains high. This prospective cohort study aimed to assess acquisition of motor and cognitive developmental milestones in early childhood and their associations with stunting and wasting. Children aged from 0 to 24 months were recruited from three provinces in Cambodia and followed up to seven times from March 2016 to June 2019, until their 5 years. Data collection included anthropometry and developmental milestones. Seven motor and seven cognitive milestones were evaluated using the Cambodian Development Milestone Assessment Tool. Associations were assessed with parametric survival models. Hazard ratios (HR) below 1 stood for lower probabilities for achieving developmental milestones. Data were available for 7394 children. At 12 months, the prevalence of stunting and wasting were 23.7% and 9.6% respectively. Both were consistently associated with delays in most motor and cognitive milestones. Stunting was strongly associated with delays in gross motor milestones (HR < 0.85; p < 0.001). Wasting was more strongly associated with delays in fine motor development and most cognitive milestones (HR < 0.75; p < 0.001). Promoting nutritional programs in the first 1000 days to prevent malnutrition is essential to further the optimal growth and motor and cognitive development of Cambodian children.
Studies have shown an association between Early Childhood Caries (ECC) and respiratory infections; however, most have been cross-sectional, and all have been in high-income countries. Inverse probability treatment weighting (IPTW) was applied to longitudinal data from the Cambodia Health and Nutrition Monitoring Study. An analytical sample of 1703 Cambodian children between 1- and 4-years old was used to examine the effect of caries incidence (ECC Activity) on the odds of a child subsequently experiencing an episode of prolonged coughing (>14 days) over the subsequent 18 m. ECC activity occurred among 523 children (30.7%) while prolonged coughing was observed among 235 children (13.8%). ECC activity increased the risk of prolonged coughing (RR 1.23; 95% CI 0.95, 1.58; Average treatment effect = 3%). Follow-up investigations are justified in order to examine whether ECC may be a modifiable risk factor for prevention of respiratory illness among young children.
