Childhood Overweight

Overweight and Obesity in Preschool Children, Prevalence and Prevention - Family Based Health Interventions for Child Health

To evaluate the effects of a family-based intervention program intended for parents of pre-school children (4-6 y) with overweight and obesity (according to Cole et al), and to investigate if treatment has an effect on metabolic parameters. In a randomised controlled trial evaluate the three separate family based intervention programs and to investigate if treatment has an effect by correlating the parameters described above with BMI, before and after the intervention program.

The aim is to investigate the possibility of preventing the development of obesity in early childhood. To evaluate the effects of a family-based intervention program intended for parents of pre-school children (4-6 y) with overweight and obesity (according to Cole et al), and to investigate if treatment has an effect on metabolic parameters. To compare different methods of treatment by randomizing the families into groups with various treatment during one year; (A) internet based information and communication tool "Sundabarn.se"(B) psychologist directed seminars with different themes, giving parents tools to implement necessary changes in family-patterns and life style, combined with A, (C) occupational therapist directed group-treatment intended to help parents alter their daily life patterns and, combined with A, (D) control group. To analyse the aetiology and prognosis of overweight and obesity in early childhood, by measuring the following variables: heredity, genetics, perinatal, physiological, metabolism, bio-chemical, clinical, psychological, socio-economic. In a randomised controlled trial evaluate the three separate family based intervention programs and to investigate if treatment has an effect by correlating the parameters described above with BMI, before and after the intervention program. To calculate the prevalence of overweight and obesity among pre-school children in the county of Middle Skåne during a 20 year period. To analyse parents actual utilization of the Sundabarn.se and in association with primary and secondary outcome. To analyse the cost-effectiveness of the intervention programs. The primary outcome variable, BMI of the children, is measured at inclusion, after six months, at exclusion and one year after end of program. Following variables are investigated and related to BMI of children before and after intervention: Heredity: BMI of parents, history . Socio-economic background: education, salary, language, occupation of parents. Perinatal data: Mothers BMI, parity, smoking, ponderal index of infant, gender, breast-feeding. Psychological variables: grading of parents experienced stress and control and psychological health of the child, before end after intervention. Are there a correlation between change in these factors and change in BMI of the child after the intervention? Physiological variables: Sleep duration and activity patterns in the children and compare them to BMI Analysing sleep duration and activity with an accelerometer. Analysing dietary of children: diet registration Analysing the change of bio-chemical markers in blood of children before and after intervention: metabolism of insulin (glc, insulin, C-peptide, pro-insulin, HBA1C) lipids (TG, HDL, LDL, cholesterole), adipokins and cytokins (leptin, adinopektin, resistin, haptoglobulin, IL-6, TNFalfa),ghrelin before and after a meal, thyroid (TSH, T3). Analysing the bacteria of the gastro-intestinal tract by sample from stools. Utilization of SundaBarn.se: automatic, electronic measurement by single user identity of number of sessions, pages visited, inputs made and downloads. Intervention health-care resource use: Protocol driven visits to physician, nurse, occupational therapist, psychologist, dietitian.
