1 Hvorfor er overvekt hos barn alarmerende? Hva er det som skjer
Overlege Dr.Med Bård Kulseng Regionalt senter for behandling av sykelig overvekt St. Olavs Hospital og NTNU

2 Hvorfor er overvekt hos barn alarmerende?
Vi vet ikke sikkert hva overvekten kommer av og hvordan den skal bekjempes. Men den skyldes at et overskudd av kalorier bygger seg opp Den fører til redusert livskvalitet og sykdom. Den øker i befolkningen Den påvirker neste generasjon Den er en økonomisk og sosial belastning på vårt samfunn Påvirker stabilitet i vårt samfunn Øker forskjell i levekår

6 Endring i insidenser og sykdomspanorama Har vi et helsevesen som er tilpasset nye utfordringer

7 Hvorfor endring i befolkningen
Økt energi inntak (fett og sukker). Feil mat Mindre fysisk aktivitet Sykdom? Miljøforurensninger? Påvirket foster Arv og endring i gener som aktiveres ????????

21 Biology's influence during obesity development, treatment, and relapse.
Biology's influence during obesity development, treatment, and relapse. Homeostatic systems adapt to prevent perpetual weight loss or gain when environmental and behavioral pressures change. The interplay of this balance between the changes in nonhomeostatic pressures and homeostatic adaptations is shown for the initial development and progression of obesity (A–C), during energy-restricted weight loss (D), during weight maintenance after weight loss (E), and during the relapse to obesity (F). Biology may play a more subtle, permissive role during the initial development of obesity, but it becomes a driving force for weight regain after weight loss. MacLean P S et al.

Fig. 2. A new formulation for appetite control. A proposed tonic signal for the drive to eat that reflects the body’s demand for energy arises (mainly) from FFM and RMR. In turn, this drive is under tonic inhibition from leptin, whose action reflects the amount of stored energy reserves in the body. As the amount of adipose tissue increases, leptin insensitivity occurs and this tonic inhibition is reduced. The drive to eat is periodically interrupted and suppressed by episodic signals in the form of peptides that are released from the GI tract in response to food consumption. The resulting pattern of eating is a consequence of the interactions between tonic and episodic physiological signals. The figure also illustrates the postulated effect of exercise on appetite control. Prolonged exercise displays a dual-process action by stimulating hunger (an effect that is highly variable between individuals) but also by increasing post-prandial satiety signalling (King et al., 2009) through an effect on GI peptides (Martins et al., 2010).

23 Figure 1 The “limbic triangle
Figure 1  The “limbic triangle.” Three areas of the CNS conspire to drive food intake and reduce physical activity, resulting in persistent weight gain. The ventromedial hypothalamus (VMH) transduces the leptin signal from adipocytes to reduce energy intake and increase energy expenditure; however, hyperinsulinemia prevents leptin signaling, promoting the “starvation response.” The ventral tegmental area (VTA) transduces the leptin signal to reduce dopamine neurotransmission to the nucleus accumbens (NA), reducing food intake; however, hyperinsulinemia prevents leptin signaling here as well, increasing dopamine and promoting the “reward” of food. The amygdala transduces fear and stress, which results in increased cortisol release from the adrenal cortex. The elevated cortisol also drives energy-rich food intake and promotes insulin resistance, further interfering with leptin signaling at the other two CNS sites. Thus, activation of any aspect of the limbic triangle turns on a positive feedback loop, promoting continued weight gain and obesity.

26 Individuality and epigenetics in obesity
Periods of life in which DNA methylation processes take place. Erasure of methylation imprints is almost exclusively of two stages: primordial germ cells and blastocyst development. Maternal care, ageing and different environmental factors (such as dietary components, some toxins and drugs, inflammation and perhaps physical activity) regulate the methylation processes in the different periods of life. © This slide is made available for non-commercial use only.

27 Bariatric surgery for mothers protects offspring from obesity
Born before (48) Mother’s surgery (BMI 48) Before after (172) mothers’ surgery (BMI 31) * Bariatric surgery for mothers protects offspring from obesity Caloric restriction during pregnancy may affect development of offspring. This study followed the growth to adolescence of offspring of obese mothers who gave birth prior to, or following substantial weight loss following bariatric surgery (biliopancreatic diversion [BPD]). The prevalence of overweight or obesity was markedly and significantly lower among children born post-surgery, compared to those born pre-surgery. The difference appeared to be gender specific, with most of the effect occurring in boys. Kral JG, Biron S, Simard S et al. Large maternal weight loss from obesity surgery prevents transmission of obesity to children who were followed for 2 to 18 years.

35 Konklusjon Årsakene til fedme hos barn er sammensatte
Antall barn med fedme er for høyt Barnefedme fører til redusert helse hos barnet og risikoen drar barnet med seg i voksen alder Barnefedme har konsekvenser for et bærekraftig samfunn
