Implementing multiple intervention strategies in Dutch public health-related policy networks.

Improving public health requires multiple intervention strategies. Implementing such an intervention mix is supposed to require a multisectoral policy network. As evidence to support this assumption is scarce, we examined under which conditions public health-related policy networks were able to implement an intervention mix. Data were collected (2009-14) from 29 Dutch public health policy networks. Surveys were used to identify the number of policy sectors, participation of actors, level of trust, networking by the project leader, and intervention strategies implemented. Conditions sufficient for an intervention mix (≥3 of 4 non-educational strategies present) were determined in a fuzzy-set qualitative comparative analysis. A multisectoral policy network (≥7 of 14 sectors present) was neither a necessary nor a sufficient condition. In multisectoral networks, additionally required was either the active participation of network actors (≥50% actively involved) or active networking by the project leader (≥monthly contacts with network actors). In policy networks that included few sectors, a high level of trust (positive perceptions of each other's intentions) was needed-in the absence though of any of the other conditions. If the network actors were also actively involved, an extra requirement was active networking by the project leader. We conclude that the multisectoral composition of policy networks can contribute to the implementation of a variety of intervention strategies, but not without additional efforts. However, policy networks that include only few sectors are also able to implement an intervention mix. Here, trust seems to be the most important condition.

Breastfeeding and food pattern in overweight children in the Caribbean.

BACKGROUND: As in most countries around the globe, overweight and obesity are a major threat to public health on the Caribbean island of Aruba. Increasing evidence confirms that breastfeeding protects against overweight and obesity. However, little is known about the mechanism underlying the association between breastfeeding and obesity. One possibility is that breastfed infants are better able to control their meal size and intervals than formula-fed infants. This might lead to a healthier diet in later life and protect against overweight and obesity. OBJECTIVE: To determine the relationship between breastfeeding, food pattern and being overweight in the Caribbean. METHODS: In a cross-sectional school-based study in 2004-2005, weight and height were measured by two research assistants in 1776 children aged 6-11 years on Aruba, an island in the Caribbean. BMI was defined according to guidelines by the International Obesity Task Force. Parents completed a questionnaire pertaining to breastfeeding and dietary food pattern. RESULTS: 1451/1776 (81·7%) children were breastfed; 851/1766 (47·9%) children were breastfed for <4 months, 227/1776 (12·8%) for 4-6 months and 373/1776 (21·0%) for ≥6 months. Children who were breastfed for ≥4 months had lower odds (OR 0·32, 95%CI 0·25-0·40) of being overweight including obesity than those who either were not breastfed or who were breastfed for <4 months. Children who were breastfed for ≥4 months were more likely to have a structured food pattern of six eating moments a day (OR 7·43, 95% CI 5·87-9·39, P<0·001) and to have breakfast every day (OR 2·86, 95% CI 2·17-3·78, P<0·001) than those who were not or who were breastfed for <4 months. CONCLUSIONS: Breastfeeding for ≥4 months is associated with a structured food pattern (six eating moments a day including a daily breakfast) and carries a strikingly lower risk of overweight in children. Promoting prolonged breastfeeding together with a focus on a subsequent structured food pattern could be a cheap method of preventing overweight.
