Abstract [en]

Estimating energy intake (EI) of a child by using a diet history interview (DHI) method may be a challenge because of difficulties for the child to remember what has been eaten as well as to report portion sizes. The aim of this research was to validate reported EI from a DHI in children classified as overweight or obese by comparing the reported EI to total energy expenditure (TEE) measured by two objective measures. Eighty-five 10.5 ± 1.1 y old overweight and obese children, with help from one or two parents, reported their EI two weeks retrospectively in a DHI. Reported EI was compared with TEE, as measured by SenseWear Armaband (n=85) and the doubly-labelled water (DLW) method (n=21), during the same period as the DHI. Reported EI was under-estimated by 14 % when validated against both the armband and DLW method. Under-estimation did not differ between boys and girls. However, the EI of obese children was under-estimated by 22 %, which is twice the rate as for the overweight children (95% CI: 0.55, 3.08). Under-estimated EI was negatively correlated with body mass index (BMI) (r=-0.38, P= <0.01) as well as age (r=-0.21, P=0.05). EI is under-estimated to a higher extent among children with higher BMI and higher age when using a DHI method. The findings show the importance of validating dietary intake of children in general and in overweight and obese children in particular.

Abstract [en]

Background Childhood overweight and obesity have increased during the past decades and there is a need for effective intervention programs both for treatment and prevention to interrupt the increased trend. Overweight and obesity result from a combination of genetic predisposition and lifestyle where an imbalance in energy intake (EI) and total energy expenditure (TEE) is the key factor. The objective of this thesis is to evaluate the impact of a 2-year lifestyle intervention on food habits, anthropometry and metabolic markers on children with overweight and obesity.

Methods Overweight and obese children 8-12 years old were recruited to participate in a 2-year randomized controlled trial (RCT). One hundred and five children agreed to participate and were randomized into one intervention group and one control group. Both groups participated in the same measurements while the intervention group also participated in a lifestyle program aiming at improving food habits and increasing physical activity. The first year of the program consisted of 14 group sessions and the second year of the intervention was web-based. Food habits were assessed at baseline and at endpoint by a diet history interview (DHI) and by a 4-day food record at 1-year measurement. At baseline 22 randomly chosen children were included in a validation study to validate reported EI against TEE measured by doubly labeled water (DLW) method and SenseWear Armband Pro 2 and 3 (version 5.1) (SWA). Anthropometric and biochemical parameters were measured at baseline, 1-year and endpoint.

Results The DHI underestimated EI by 14% when validated against measured TEE by DLW and SWA. At the 1-year measurement the intervention group had a lower intake of fat (g and E%), monounsaturated fat (MUFA) (g) and polyunsaturated fat (PUFA) (g and E%) compared to the control group. At endpoint the intervention group had a lower intake of fat (g), MUFA (g) and cholesterol compared to the control group. Children in the intervention group consumed less sugar sweetened beverages at endpoint and had increased their intake of keyhole labeled foods compared to the control group. During the first year the growing children in both groups remained stable with respect to BMI and had decreased their BMI zscore.

Conclusion The 2-year lifestyle intervention resulted in some improvements regarding food habits, but overall the effects on anthropometrics and metabolic markers were limited. This strongly supports that efforts should primarily be aimed at primary prevention of childhood overweight and obesity.
