[Alternative causes of obesity].

The prevailing understanding of the causes of obesity is based on the disturbance of the thermodynamic law of energy balance, primarily through increased intake or decreased expenditure of energy. Alternative causes of obesity, which still respect the law but also allow for primary fat accumulation, are: virus infection of fat cells, energy supply from bacterial fermentation of indigestible food components, psychosocial factors mediated by psychoneuroendocrine pathways, sleeplessness or poor quality of sleep and early life programming, in addition to the well-known and proven genetic programming.

Upward weight percentile crossing in infancy and early childhood independently predicts fat mass in young adults: the Stockholm Weight Development Study (SWEDES).

BACKGROUND: Rapid early postnatal weight gain predicts increased subsequent obesity and related disease risks. However, the exact timing of adverse rapid postnatal weight gain is unclear. OBJECTIVE: The objective was to examine the associations between rapid weight gain in infancy and in early childhood in relation to body composition at age 17 y. DESIGN: This prospective cohort study was conducted in 248 (103 males) singletons and their mothers. Height and weight were measured at birth, 6 mo, and 3 and 6 y. The rates of weight gain during infancy (0-6 mo) and early childhood (3-6 y) were calculated as changes in sex- and age-adjusted weight SD scores during these time periods. At 17 y, body composition was measured by air-displacement plethysmography. RESULTS: Increasing weight gain during infancy and early childhood were both independently associated with larger body mass index, fat mass, relative fat mass, fat-free mass, and waist circumference at 17 y (P < 0.005 for all; adjusted for sex, birth weight, gestational age, current height, maternal socioeconomic status, and maternal fat mass). Rapid weight gain in infancy, but not in early childhood, also predicted taller height at 17 y (P < 0.001). CONCLUSIONS: Rapid weight gain in both infancy and early childhood is a risk factor for adult adiposity and obesity. Rapid weight gain in infancy also predicted taller adult height. We hypothesize that rapid weight gains in infancy and early childhood are different processes and may allow separate opportunities for early intervention against obesity risk later in life.

Locus of control and weight reduction.

The objective of this study was to determine if locus of control orientation is predictive for weight loss among participants in a behaviour modification weight reduction programme. The subjects completed a locus of control questionnaire consisting of 40 questions before starting the programme and again after 1 year. Forty-one participants started the programme, 28 remained after 1 year. Their weight loss was significant (P < 0.001) and associated with an internal locus of control orientation (P < 0.05). The findings suggest that different weight reduction activities could be offered depending on the person's locus of control orientation. Participants with an internal orientation could be offered a standard weight reduction programme. Others, with a more external locus of control orientation, could be offered an adapted programme, which also focused on and encouraged the participants' internal orientation.

Education and supervision of health care professionals to initiate, implement and improve management of obesity.

The objective of this study was to explore whether there were differences in organisational setting and professional intervention between health professionals who, after 1 year of education, and ongoing supervision for all together 30 months, started obesity treatment and those who did not. Furthermore to analyse what factors facilitate the start of obesity treatment. One hundred and seventy-one health professionals from different parts of Sweden were included in the education. One hundred and thirty-five health professionals remained in the study for up to 2.5 years. Eighty-seven subjects started the obesity treatment program, whereas 48 subjects had no possibility to start treatment. Significantly more of those who started the behavioural treatment program had previous theoretical education and clinical experience of obesity. They also, to a greater degree, had a go-ahead from the management and support from physicians, colleagues and were more likely to be part of a team or had a colleague to work with. In addition, they could find the time to organise and plan the treatment. Supervision had a significant positive influence on starting up the treatment program. Education, working organization, a structural behavioural treatment program, seems to be significant factors in facilitating and increasing the likelihood for a start.

Sibutramine treatment in obesity: initial eating behaviour in relation to weight loss results and changes in mood.

The aim of the study was to study the role of initial eating behaviour for subsequent weight loss in treatment with sibutramine (Reductil, Meridia) an anti-obesity drug enhancing satiety, and also to assess changes in mood during the treatment. The participants were 36 obese patients with a mean BMI of 39 kg m(-2). Eating behaviour was assessed with the three factor eating questionnaire (TFEQ), and depressive features with the comprehensive psychopathological rating scale (CPRS). Sibutramine (15 mg) was administered daily. The TFEQ restraint scale was negatively related to 6 months weight loss. In particular, strategic dieting behaviour and a more controlled attitude towards self-regulation were negatively related to weight loss. A positive non-placebo controlled change in mood was found already after 2 months treatment. The changes in mood were not related to the weight loss. Patients with more unrestrained eating seem to have reduced their amount of food intake more radically with enhanced satiety, manifested by greater weight loss. Physiologically enhanced satiety could have the greatest weight loss effect for patients whose eating is more governed by hunger drives and appetite rather that by conscious efforts and cognitive control.

Associations between physical activity and fat mass in adolescents: the Stockholm Weight Development Study.

BACKGROUND: Obesity is multifactorial. However, the accumulation of fat mass (FM) is proposed to be due to a positive energy balance, which may be caused by reduced physical activity (PA). OBJECTIVE: The objectives of the study were to describe the independent associations between PA and FM in adolescents and to describe the intergenerational association of FM between mothers and their offspring. DESIGN: We conducted a cross-sectional study in 445 (190 M, 255 F) 17-y-old adolescents and their mothers. PA was assessed with a self-reported questionnaire and validated by comparison with accelerometric data in a subsample of the cohort. Body composition was measured by using air-displacement plethysmography. RESULTS: Males were significantly more active than were females (P<0.01). PA was significantly and inversely associated with FM (beta=-3.63, P=0.005) and percentage FM (beta=-3.117, P=0.017) in males but not in females (beta=-0.576, P=0.54; beta=-0.532, P=0.59, respectively) after adjustment for birth weight and maternal FM and education level. However, FM and percentage FM in females were significantly associated with maternal FM (beta=0.159, P<0.0001; beta=0.145, P=0.002, respectively) and education level (beta=-1.048, P<0.005; beta=-1.085, P=0.006, respectively). No such associations were observed in males. CONCLUSIONS: PA was independently associated with FM in males but not in females. The data also showed an intergenerational association of FM between mothers and their daughters but not between mothers and their sons.
