Maternal feeding styles in infancy predict child body mass index z-scores at 72 months: findings from a cohort of Jamaican children.

Objective: To explore whether maternal feeding styles at 12 months predict child Body Mass Index (BMI) z-scores at 72 months and evaluate whether BMI z-scores at 18 months mediates the association. Methods: Data from 239 mother-child pairs participating in a parenting intervention were analyzed. Feeding information was ascertained at 12 months by questionnaire with feeding styles identified using factor analysis. Children's weight and length/height were measured at 18 and 72 months and BMI z-scores computed. Maternal sociodemographic data, depressive symptoms and language skills were obtained by questionnaire. Multilevel linear regression analysis was used to examine whether feeding styles predicted 72 month BMI z-scores. Complete case analysis was conducted and multiple imputation used to treat missing values of explanatory and outcome variables at 18 and 72 months. Mediational analysis was performed to assess the indirect effects of feeding styles on 72 month BMI z-scores via 18 month BMI z-scores. Results: Restrictive feeding at age 12 months predicted higher 72 month BMI z-scores in both complete case analysis [ß (95%CI): 0.19 (0.02, 0.37)] and multiple imputation [ß (95%CI): 0.20 (0.02, 0.39)]. Uninvolved, forceful, indulgent and responsive feeding styles were not significant predictors of 72 month BMI z-scores. A significant indirect effect was observed between restrictive feeding and child BMI z-scores at 72 months via 18 month BMI z-scores [ß (95% CI) 0.12 (0.03, 0.22)]. Conclusion: Restrictive feeding at 12 months was associated with higher BMI z-scores at 72 months and appeared to be mediated by BMI z-scores at 18 months.

Association of Perceived Neighbourhood Walkability with Self-Reported Physical Activity and Body Mass Index in South African Adolescents.

Adolescence is a life stage critical to the establishment of healthy behaviours, including physical activity (PA). Factors associated with the built environment have been shown to impact PA across the life course. We examined the sociodemographic differences in, and associations between, perceived neighbourhood walkability, PA, and body mass index (BMI) in South African adolescents. We recruited a convenience sample (n = 143; 13-18 years; 65% female) of students from three high schools (middle/high and low-income areas). Participants completed a PA questionnaire and the Neighbourhood Environment Walkability Scale (NEWS)-Africa and anthropometry measurements. Multivariable linear regression was used to examine various relationships. We found that, compared with adolescents living in middle/high income neighbourhoods, those living in low-income neighbourhoods had lower perceived walkability and PA with higher BMI percentiles. The associations between neighbourhood walkability and PA were inconsistent. In the adjusted models, land use diversity and personal safety were associated with club sports participation, street connectivity was positively associated with school sports PA, and more favourable perceived walkability was negatively associated with active transport. Overall, our findings suggest that the perceived walkability of lower income neighbourhoods is worse in comparison with higher income neighbourhoods, though the association with PA and BMI is unclear.

A cross-sectional analysis of investigator needs for non-communicable disease research at the University of the West Indies, Mona.

OBJECTIVE: To describe the needs of academic staff conducting non-communicable disease (NCD) research at the University of the West Indies, Mona Campus in Jamaica. METHODS: Utilizing a cross-sectional design an online survey was created using the research electronic data capture application (REDCap); it was disseminated via email to 708 academic staff members in the Faculties of Medical Sciences and Science & Technology between September and November 2018. Participants were asked to indicate their level of access to expertise, training and equipment for conducting research. Descriptive analysis was conducted using STATA version 14. RESULTS: Most respondents were women (74.2%), predominantly scientists (33.1%) or specialist physicians (22.6%). Less than 2/3 of respondents reported publishing research findings in peer reviewed journals, with a quarter not disseminating their research findings in any medium. Resources for field research/data collection, epidemiological methods and principles, and data management/data analysis were generally available. However, there was limited access to training, expertise and equipment in emerging techniques for NCD research such as metabolomics, bioinformatics/analysis of large-scale data sets and health economics. Additional challenges included limited access to financing for research, inadequate workspace and poor administrative support for conducting research. CONCLUSIONS: There is a need for more local research seed funding, stronger administrative support for researchers, and opportunities for training in cutting edge NCD research techniques. Jamaican researchers could benefit from being part of a regional research centre of excellence with critical research skills and equipment that builds research networks and strengthens the NCD research response.

Level of agreement between adolescents' self-assessment and parent proxy report of health-related quality of life in adolescents with sickle cell disease.

BACKGROUND: We aim to assess the levels of agreement between parents, as proxies, and Jamaican adolescents living with sickle cell disease (SCD) in the reporting of the adolescent's quality of life. PROCEDURES: This cross-sectional study assessed 102 patient/proxy pairs on quality of life of adolescents with SCD using the PedsQL-SCD module. The level of agreement among pairs was assessed starting with broad group-level approaches (the Wilcoxon signed-rank test augmented by exploring percentage agreement) tapering to individual-level approaches (intraclass correlation coefficients [ICCs] supplemented with Bland-Altman plots). RESULTS: Most patients (76.5%) had homozygous SS disease (45.1% females; mean age 15.2 ± 1.5 years). Median total pediatric quality of life (PedsQL) scores were 79.1 (adolescent report) and 80.2 (parental report) (P = .60). There were 11.8% underestimation and 12.7% overestimation of overall health-related quality of life (HRQOL) by parents. The highest perfect agreement existed on the "pain and hurt" domain for both male and female adolescents (85.7% and 84.4%, respectively). Overestimation was highest on the "social communication" domain for both male and female adolescents (19.6% and 34.8%, respectively). Parents exhibited good agreement on total PedsQL scores in male adolescents (ICC = 0.70), but moderate agreement (ICC = 0.43) in female adolescents. Generally, parents underestimated their male child's functioning and overestimated the female child's functioning on the various domains. CONCLUSIONS: Parents and adolescents exhibit fair agreement in assessment of the adolescent's overall HRQOL but differ on subjective domains. Agreement varies by sex of the affected teen where girls' HRQOL is generally overestimated by the parental proxy. Interventions to improve parents' understanding of their children's psychosocial needs are needed.
