Emotional Eating and Binge Eating Disorders and Night Eating Syndrome in Polycystic Ovary Syndrome-A Vicious Circle of Disease: A Systematic Review.

Obesity is an established risk factor for the development of polycystic ovary syndrome (PCOS), especially phenotype A. PCOS is an important cause of fertility disorders in a large group of women of reproductive age. For many years, effective methods of treating hormonal disorders associated with PCOS have been sought in order to restore ovulation with regular menstrual cycles. Numerous studies support obesity treatment as an effective therapeutic method for many women. A seemingly simple method of treatment may prove to be particularly difficult in this group of women. The reason for this may be the lack of recognition the primary cause of obesity development or the occurrence of a vicious circle of disease. Primary causes of developing obesity may be emotional eating (EE) and eating disorders (EDs), such as binge eating disorder (BED) and its extreme form, addictive eating, as well as night eating syndrome (NES). All of these are caused by impaired function of the reward system. Consequently, these disorders can develop or be exacerbated in women with obesity and PCOS as a result of depression and anxiety related to hirsutism and fertility disturbances. Therefore, for the effective treatment of obesity, it is very important to recognize and treat EE, BED, and NES, including the appropriate selection of pharmacotherapy and psychotherapy. Therefore, the aim of our manuscript is to analyze the available data on the relationships between EE, BED, NES, obesity, and PCOS and their impact on the treatment of obesity in women with PCOS.

Can Nutritional Status in Adults Be Influenced by Health Locus of Control?

The external health locus of control (HLC) is based on an assumption that obtained health results depend on the influences of external factors. As for the internal HLC-that is the effect of our own actions and capabilities. Little is known regarding how the HLC can influence body weight or the occurrence of visceral obesity. The study aimed to assess the relationship between the health locus of control and nutritional status in adults. The study included 744 adults (452 women, 292 men; 2.8% underweight, 43.8% normal weight, 29.7% overweight, and 23.7% obese). In addition to anthropometric measurement and socio-demographic data, the health locus of control, using the Multidimensional Health Locus of Control Scale (MHLC) by Wallston K, Wallston B, and DeVellis R, was assessed. The percentage of subjects with an internal HLC did not differ significantly between obese, overweight, and normal-weight groups. However, the percentage of subjects with an external HLC-dependent on the impact of others-was significantly higher in both men and women with obesity than in corresponding overweight and normal-weight groups (p < 0.01). Yet, the percentage of subjects with an external HLC subject to the impact of chance was significantly higher among overweight and obese women than in those of normal weight (p < 0.05) only. Women with overweight or obesity, with external health locus of control, experienced both the impact of others and of chance more often than women with normal weight. However, men with overweight and with obesity more often had external health locus of control influenced only by others.

Perception of body size and body dissatisfaction in adults.

Self-perception of body size seems to be not always in line with clinical definitions of normal weight, overweight and obesity according to Word Health Organization classification. The effect of self-perception of body size disturbances and body dissatisfaction may be the development of eating disorders, such as anorexia nervosa or binge eating disorder-a major risk factor of obesity development. Therefore, the study aimed to assess separately the perception of weight status and body size as well as body dissatisfaction in adults with normal weight, overweight and obesity. The study included 744 adults (452 women; 35.9 ± 12.4 years; 21 underweight, 326 normal weight, 221 overweight, 176 obese) referred to Metabolic Management Center and volunteers. Body size perception and body dissatisfaction were assessed based on Stunkards' Figure Rating Scale (FRS). Additionally, participants' were asked: 'Do you think you are: underweight/normal weight/overweight/obese?' to assess perception of weight status. Participants' weight and height were measured to calculate body mass index (BMI) after completing the FRS. Individuals within the overweight BMI range have rated themselves as underweight (1.4%), normal weight (30.8%) and obese (2.8%). Also individuals within the obesity BMI range have rated themselves as normal weight (2.6%), and overweight (41.6%). Compatibility of self-assessment of weight status with BMI category according to the measured values was moderate-Kappa coefficient was 0.59 (95% CI: 0.54-0.64). Underestimation of weight status was significantly more common among men than women. There were statistically significant differences in the distribution of body dissatisfaction according to the weight in both women and men. Normal-weight subjects less often than overweight and obese were dissatisfied with their own body size. The degree of body dissatisfaction was greater among women than among men. Adults subjects frequently underestimate their own weight status and body size. Women with overweight and obesity more often than men are dissatisfied with their own body size.

Is there a difference in body size dissatisfaction between the patients with obesity seeking and not seeking treatment for obesity?

BACKGROUND: Various factors motivate people to undertake treatment for obesity. Among others they include health benefits, willingness to please others, and dissatisfaction with one's appearance. The present study aimed to assess body size dissatisfaction in patients with obesity seeking and not seeking treatment for obesity. METHODS: Two-hundred-sixteen adult subjects (154 women, 62 men) including 80 people with BMI ≥ 30 kg/m2 starting treatment for obesity (BMI 35.7 ± 5.3 kg/m2) and 136 volunteers with obesity (BMI 34.7 ± 4.3 kg/m2) not seeking treatment for obesity, were enrolled. Body size satisfaction was assessed using the Figure Rating Scale adapted by Stunkard. RESULTS: Patients with obesity starting obesity treatment had more often a high level of body size dissatisfaction than volunteers with obesity not seeking the treatment (p <  0.001). There was a significant difference in the distribution of body size dissatisfaction in women (p <  0.05), but not in men (p = 0.47). CONCLUSION: Patients with obesity, especially women, seeking obesity treatment more often represent a high level of body size dissatisfaction than volunteers with obesity not seeking treatment for obesity. This implies the need for public health campaigns to address negative attitudes or misconceptions about obesity and its treatment. Placing more attention and emphasis on body size dissatisfaction in more vulnerable women with obesity may help to define personal motivations and goals, strengthen the doctor-patient relationship and better adapt therapeutic strategies.

The occurrence of depressive symptoms in obese subjects starting treatment and not seeking treatment for obesity.

INTRODUCTION: The psychological profile of obese people deciding to start obesity treatment may be different from those not choosing to seek the therapy. Previous studies have shown a higher incidence of depression in obese than in normal weight people. However, data are lacking concerning the occurrence of depressive symptoms and their severity in obese subjects who do or do not decide to start treatment for obesity. Therefore, the aim of this study was to evaluate the prevalence and severity of depressive symptoms among obese people starting treatment and not seeking treatment for obesity. MATERIALS AND METHODS: Enrolled subjects were 331 adults (241 women, 90 men), including 193 obese subjects starting treatment for obesity (46.8 ± 13.2 years, BMI 37.6 ± 5.5 kg/m2) and 138 obese volunteers never seeking treatment for obesity (44.3 ± 12.5 years, BMI 34.7 ± 4.3 kg/m2). Depression levels were determined using the Beck Depression Inventory (BDI). RESULTS: The level of depression was significantly higher among those starting treatment for obesity than those never seeking treatment for obesity (13.2 ± 9.2 vs. 9.5 ± 7.9 points; p < 0.001). This difference was statistically significant in women (14.4 ± 9.2 and 11.0 ± 8.2 points, respectively; p < 0.01), but not in men (7.2 ± 6.4 and 7.3 ± 7.1 points, respectively; p = 0.95). There were more women with moderate/severe depressive symptoms in the group starting treatment than in the group not seeking treatment for obesity (44.7 and 24.4%, respectively). No such difference was observed in men. CONCLUSIONS: Obese subjects, especially women, with depressive symptoms are more likely to start treatment for obesity. LEVEL OF EVIDENCE: Level III, case-control analytic study.
