“…Moreover, under-reporting was also independently associated with perceiving one's weight as too light. This may be due to the excessive weight concerns and strong desire for thinness commonly observed in young Japanese women, irrespective of actual weight status (19,20). A similar independent infl uence of both actual weight status and perceived weight consciousness on underreporting has been observed in other obese populations (10,14).…”

“…A characteristic of young Japanese women is their relatively low BMI, which is nevertheless accompanied by excessive weight concerns and a strong desire for thinness (19,20), a combination seldom observed in other countries. In particular, we investigated the hypothesis whether actual and perceived weight statuses were independently associated with energy intake misreporting in this unique population.…”

Summary Evidence on factors associated with misreporting of energy intake is limited, particularly in non-Western populations. We examined the characteristics of under-and over-reporters of energy intake in young Japanese women. Subjects were 3,956 female Japanese dietetic students aged 18-20 y (mean body mass index: 20.9 kg/m 2 ). Energy intake was assessed using a comprehensive self-administered diet history questionnaire. Estimated energy requirement was calculated based on self-reported information on age, body height and weight, and physical activity with the use of an equation from the US Dietary Reference Intakes. Under-, acceptable, and over-reporters of energy intake were identifi ed based on the ratio of energy intake to estimated energy requirement, according to whether the individual's ratio was below, within, or above the 95% confi dence limits of the expected ratio of 1.0 (Ͻ0.70, 0.70-1.30, and Ͼ1.30, respectively). Risk of being an under-or over-reporter of energy intake compared to an acceptable reporter was analyzed using multiple logistic regression. The percentage of under-, acceptable, and over-reporters of energy intake was 18.4, 73.1, and 8.4%, respectively. Under-reporting was associated with overweight or obesity, perception that one's own weight was too heavy or light, lower dietary consciousness, active lifestyle, living without family, and living in a city (compared with a metropolitan area). Over-reporting was associated with sedentary lifestyle only. This study of lean young Japanese women showed that energy intake misreporting, particularly under-reporting, was common and differential among populations. Particularly, perceived weight status was associated with under-reporting of energy intake, independent of actual weight status.

“…We cannot rule out the possibility that the association between rate of eating and overweight observed here was the result of post hoc changes in dietary behavior (in a healthier direction) as a consequence of overweight. This may be particularly relevant in female populations, given the excessive weight concerns observed in young Japanese women (24,25). These concerns may explain why the association was relatively weak in female adolescents.…”

SummaryThe possible role of eating rate in promoting obesity has long been of interest. We examined the association between rate of eating and overweight status in Japanese children and adolescents. This Japanese cross-sectional study included 15,974 children (6-11 y; 7,956 boys and 8,018 girls) and 8,202 adolescents (12-15 y; 3,944 boys and 4,258 girls). Rate of eating was self-reported according to fi ve categories. Body mass index (BMI) was calculated from self-reported body weight and height. Overweight was defi ned according to the International Obesity Task Force age-and sex-specifi c BMI cutoffs. The overall prevalence of overweight was 13.2%. Rate of eating was positively associated with the risk of overweight, independent of protein, fat, and dietary fi ber intakes. Multivariate odds ratios (95% confidence intervals) for overweight in the very slow, relatively slow, medium, relatively fast, and very fast categories were 0. In conclusion, this large cross-sectional study in Japan showed that a higher rate of eating was independently positively associated with an increasing risk of overweight in children and adolescents.

“…29 A study carried out in Japan on body perceptions found that women had a poor understanding of their heaviness/fatness in relation to their actual body weight. 30 Even though, or especially because, the general population have such misperceptions about their weight (either overweight or underweight), it is vital that HCW accurately perceive their own weight status in order to be able to perform their roles in health care better.…”

Background: Obesity has reached epidemic proportions globally. In South Africa, 56% of white men, 49% of black men and 75% of black women have been reported to be overweight or obese. The focus of this study is on South African healthcare workers (HCW), because they are considered role models for health for patients and their communities. Objectives:The objective was to determine the prevalence of obesity and obesity-related health problems among HCW and to compare these variables between medical and nonmedical staff at one selected public hospital in South Africa.Methods: A questionnaire was distributed to 200 respondents from a balanced pool of randomly selected HCW (100 medical staff and 100 nonmedical staff). Self-reported body mass index (BMI), obesity-related health problems and perceptions about body weight were assessed.Results: Seventy-three per cent of the HCW were overweight or obese, and half of them had never tried to lose weight. Females and older HCW were more obese than men and younger counterparts. There was no difference in BMI distribution between medical and nonmedical staff. About one-third of HCW reported that they suffered from obesity-related noncommunicable diseases (NCDs; hypertension 20% and diabetes 10%) and stress (32.5%). The majority of HCW had an inaccurate perception of their own weight.Conclusion: South African HCW have a high prevalence of obesity-related NCDs. A health promotion programme targeting HCW is urgently needed to encourage weight control, urge the prevention of obesity-related NCDs and change selfperceptions of body weight, in order to improve their own health and make them better role models for the general public.Peer reviewed.
