Lifestyle intervention for children and adolescents with severe obesity - results after one year. / Livsstilsbehandling av barn og ungdom med alvorlig fedme ­ resultater etter ett år.

BACKGROUND: Lifestyle interventions for children and adolescents with severe obesity show moderate short-term effects on weight reduction internationally. We evaluated treatment results at two Norwegian specialist outpatient clinics. MATERIAL AND METHOD: We performed a retrospective analysis of data from children and adolescents between 3 and 18 years of age collected in 2012-2016. Children and adolescents with severe obesity who attended their one-year follow-up were included. We included in the analyses the following body weight measures: percentage overweight as defined by the International Obesity Task Force cut-off (% IOTF-25); BMI standard deviation score; waist circumference standard deviation score; and body fat percentage at the start of treatment and at one-year follow-up. RESULTS: Of 568 children and adolescents who started treatment, 416 (73 %) attended the one-year check-up. A total of 271 (65 %) patients achieved a reduction in %IOTF-25, while 228 patients (55 %) reduced their BMI standard deviation score. There was a statistically significant mean reduction of all four registered body weight measurements. Altogether 54 of 325 children (17 %) changed category from severe obesity to obesity, 8 (2 %) went from severe obesity to overweight, and 8 of 91 children (9 %) changed category from obesity to overweight or normal weight. The proportion of participants with a reduction of more than 5 % in %IOTF-25 was 43 % (177/416), and a reduction in BMI standard deviation score of more than 0.25 was observed in 23 % (95/416) of participants. Girls responded on average more poorly to the intervention than boys. There was no clinically significant difference in results between the treatment centres. INTERPRETATION: After one year of treatment of children and adolescents with severe obesity in two specialist healthcare centres, we found a moderate mean reduction in weight, waist circumference and body fat percentage, but with large interindividual variation.

Weight changes and mobility in the early phase after hip fracture in community-dwelling older persons.

PURPOSE: Hip fractures in older persons are associated with reduced mobility and loss of independence. Few studies address the nutritional status and mobility in the early phase after hip fracture. The objective of the present study was, therefore, to investigate weight changes and their effect on mobility during the first two months following hip fracture in community-dwelling older persons without dementia. METHODS: Patients (> 60 years) admitted for a first hip fracture were recruited from two tertiary referral hospitals in Bergen, Norway. The patients' weights and dietary intakes were determined in the hospital and at home after two months. Mobility was assessed based on the New Mobility Score (NMS) (scale 0-9, with values > 5 regarded as sufficient mobility). RESULTS: We included 64 patients (median age 80 years, 48 women, 16 men) with information on weight collected in the hospital. Follow-up measurements were available for 32 patients, corresponding to an attrition rate of 50%. The patients had a median weight loss of 1.8 kg (IQR = - 3.7, 0 kg). Most of them had reduced mobility at two months after the surgery [median NMS = 5 (IQR = 3-6)]. Both age and the weight change after surgery were predictors of the NMS at follow-up. CONCLUSION: Bodyweight loss was observed in three out of four patients in the early phase after hip fracture and was associated with decreased mobility measured by the NMS. The results should be interpreted with caution as half of the patients dropped out of the study and did not participate in the follow-up visit.
