Identifying elevated child weight from 3 to 24 months: Early transitions into nonparental care and to solid foods

BACKGROUND

Early entry into nonparental care (NPC) and introduction to solid foods (ITS) have been linked to elevated weight, however, little research exists on the combined influence of these transitions on child weight over time.

OBJECTIVES

Identify groups of children based on early NPC and ITS timing and examine whether NPC-ITS groups differentially affect child weight over time.

METHOD

Data were drawn from STRONG Kids2 (n = 468). Primary predictors include NPC (by 3M)-ITS (< or ≥6M) groups; outcome variables include child weight-for-length/height z-scores (WFL/WFHz) (3, 12, 18, and 24 months). Multilevel regression was used to examine the NPC-ITS groups as predictors of child WFL/WFHz.

RESULTS

Six groups were identified: 27% Parental Care-ITS before 6M, 31% Parental Care-ITS after 6M, 12% Daycare-ITS before 6M, 14% Daycare-ITS after 6M, 10% Kincare-ITS before 6M, and 7% Kincare-ITS after 6M. Children who were in daycare (regardless of ITS) or kincare-ITS before 6M demonstrated the highest WFL/WFHz over time, compared to their parental care counterparts.

CONCLUSIONS

NPC-ITS combinations on child WFL/WFHz across the first 2 years of life highlight the need for a partnership approach among parental and nonparental caregivers to support the feeding of infants throughout the transition to solid foods.

Examination of dietary intake of UK preschool children by varying carers: evidence from the 2008-2016 UK National Diet and Nutrition Survey

Early years caregivers can play a key role in young children's eating and the prevention of childhood obesity. The UK National Diet and Nutrition Survey (NDNS) is a large representative survey collecting detailed food and nutrition consumption data. Using these data, the aim of this study was to investigate the relationship between dietary intake of preschool children in the UK aged 2 to 4 years and accompanying adult/s. Nutrition consumption data from 1218 preschool children from years 1 to 8 of the 2008-2016 NDNS were accessed. Dietary data were captured using 3 or 4 day estimated food diaries. Regression analyses revealed significant differences in consumption when children were not accompanied by their parents. Compared with when children were with parents, children consumed significantly more energy dense meals (0·32 kJ/g, 95% CI 0·1-0·6 kJ/g), energy (62 kJ/g, (95% CI 27-97 kJ)) Na (19 mg, (95 % CI 6, 32)), added sugars (0·6 g, (95 % CI 0·1, 1·1)), vegetables (3 g, (95 % CI 1, 4)), total grams (12 g, (95 % CI 3, 21)) and saturated fat (0·2 g, (95 % CI 0·1, 0·4)) per eating occasion when accompanied by wider family. When children were accompanied by a formal childcare provider, they consumed significantly lower energy dense meals (-0·9 kJ/g, (95% CI -1·4 - -0·3 kJ/g)), less added sugars (-1·6 g, (95 % CI -2·4, -0·8)) and more fruit (12 g, (95 % CI 3, 21)) per eating occasion than when they were with their parents. The results demonstrate that non-parental caregivers might be an important target to promote healthy eating in young children. Further research is needed to establish which caregivers would benefit most.
