NOURISH Randomised Controlled Trial: Positive eating behaviours and obesity prevention
The NOURISH RCT evaluated a community based intervention for first-time mothers that promoted protective feeding practices as a primary prevention strategy for childhood obesity. Researchers investigated whether early anticipatory guidance increased ‘protective’ feeding practices that support development of health child eating behaviours, intake and growth.
Mothers were recruited from major maternity hospitals in Brisbane and Adelaide in 2008-2009 using consecutive sampling, for consent to be contacted regarding full enrolment into the study at child age 4-7 months. Upon contact at that time, 698 mothers consented to enrol in NOURISH, underwent baseline assessment and were randomised into control and intervention groups. The intervention group attended two modules, the first after baseline assessment at 4-7 months of age, and the second at child age 12-16 months of age. Each module consisted of six, fortnightly sessions with a Dietitian and psychologist, covering aspects of infant nutrition, healthy growth and feeding practices and parenting. The control group had self-directed access to universal child health services.
Child anthropometry was measured by study staff using a standard protocol, at age 4-7 months, 12-16 months, 2, 3.5 and 5 years. Mothers also competed questionnaires at these time points assessing parental feeding practices and child eating behaviour. Child dietary intake was measured using 3 days of intake at 4-7 months, 12-16 months and 2 years (1x24hr recall and 2-day food record). At 3.5 and 5 years, mothers reported child intake using a single 24-hr recall.
