Lee K. Trends in prevalence of overweight and obesity, self-perceived overweight or obesity, and weight loss efforts among older adults in South Korea, 2005-2021. Prev Med 2024; 180:107854. [PMID: 38211800 DOI: 10.1016/j.ypmed.2024.107854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 12/31/2023] [Accepted: 01/08/2024] [Indexed: 01/13/2024]
Abstract
OBJECTIVE We assessed trends in prevalence of overweight and obesity, self-perceived overweight or obesity, and efforts to lose weight among Korean older adults from 2005 to 2021. METHODS Using Korea National Health and Nutrition Examination Survey data from 2005 to 2021, we assessed prevalence of overweight and obesity (body mass index≥25 kg/m2), self-perceived overweight or obesity, and self-reported weight loss efforts among Korean adults aged ≥60 years (11,936 men, 15,966 women). Complex sample frequency and linear by linear association analyses were conducted. RESULTS The prevalence of overweight and obesity tended to increase only in men, from 28.9% to 37.2% (P for trend<0.001). The prevalence of self-perceived overweight or obesity increased from 18.9% to 35.3% in men and 32.5% to 48.6% in women (P for trend<0.001) and tended to increase regardless of their actual weight (P for trend<0.001). The prevalence of weight loss efforts increased from 17.9% to 28.8% in men and 19.2% to 38.2% in women (P for trend<0.001) and increased in men and women who were not overweight or obese and in women who were overweight or obese (P for trend<0.001). The prevalence of weight loss efforts increased in women who self-perceived themselves as overweight or obese regardless of their actual weight, and in men who self-perceived themselves as overweight or obese even though they were not (P for trend<0.05). CONCLUSIONS There were increasing trends in the prevalence of overweight and obesity in older Korean men, self-perceived overweight or obesity, and weight loss efforts in older Korean men and women.

Abstract
PURPOSE To compare relationships between self-perceived weight and self-rated health (SRH) between cancer survivors and non-cancer survivors. METHODS A cross-sectional study based on the 2014-2019 Korea National Health and Nutrition Examination Survey was conducted for the associations of self-perceived weight status, measured BMI categories, and combined categories by self-perceived weight and measured BMI with SRH in 1622 cancer survivors and 29,903 non-cancer survivors using complex samples ordinal regression analysis after adjusting for sociodemographic factors, health behaviors, and concurrent diseases. RESULTS Compared to the comparison group (those who were normal weight and self-perceived as average weight in non-cancer survivors), adjusted odds for poorer SRH were higher in cancer survivors and non-cancer survivors who were underweight and self-perceived as underweight (adjusted odds ratios[aORs], 2.69 for non-cancer survivors; 2.62 for cancer survivors), those who were normal weight but self-perceived as underweight or overweight (aORs, 1.69-2.38 for non-cancer survivors; 2.34-3.78 for cancer survivors), and those who were overweight and self-perceived as overweight (aORs, 1.52 for non-cancer survivors; 2.42 for cancer survivors). In cancer survivors, the odds for poorer SRH were greater for those who were normal weight and self-perceived as average weight (aOR = 1.84), whereas the odds were not significant for those who were underweight or overweight and self-perceived as average weight. In non-cancer survivors who self-perceived as average weight, the odds for poorer SRH were significant in those with underweight (aOR = 1.35) or overweight (aOR = 0.84). CONCLUSION According to actual weight status, the association between self-perceived weight and SRH may differ between cancer survivors and non-cancer survivors.

Association between accuracy of weight perception and life satisfaction among adults with and without anxiety and mood disorders: a cross-sectional study of the 2015-2018 Canadian Community Health Survey. J Public Health (Oxf) 2022:6572299. [PMID: 35460257 DOI: 10.1093/pubmed/fdac047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 03/28/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Weight status and weight perception have a significant impact on life satisfaction. As overweight prevalence increases in Canada, it is important to understand how accuracy of weight perception (AWP) is associated with life satisfaction. This study explored the association between AWP and life satisfaction among Canadian adults with and without anxiety and/or mood disorders. METHODS Using data from the 2015-2018 cycles of the Canadian Community Health Survey, an indicator of AWP was created to capture concordance between perceived weight and actual weight status. Univariate and multivariate Gaussian generalized linear models were assessed while stratifying by sex and presence of anxiety and/or mood disorders. RESULTS Our sample included 88 814 males and 106 717 females. For both sexes, perceiving oneself as overweight or underweight, regardless of actual weight status, was associated with lower life satisfaction (β = -0.93 to -0.30), compared to those who accurately perceived their weight as 'just about right'. Perceiving oneself as overweight or underweight was associated with more pronounced differences in life satisfaction scores in those with anxiety and/or mood disorders (β = -1.49 to -0.26) than in those without these disorders (β = -0.76 to -0.25). CONCLUSION Weight perception is more indicative of life satisfaction than actual weight status, especially in those with anxiety and/or mood disorders.

Abstract
BACKGROUND Misperception of body weight is associated with various psychological and health problems, including obesity, eating disorders, and mental problems. To date, female-specific risk factors, including socioeconomic or health-related lifestyle features, or their indicative performance for the misperception in Asian women according to age groups remain unknown. OBJECTIVES To investigate the prevalence and associated risk factors for the mismatch in self-perceived body weight and evaluated the classification performance of the identified risk factors across age groups in female adults. METHODS We analyzed data of 22,121 women (age 19-97 years) from the 7-year Korea National Health and Nutrition Examination Survey dataset (2010-2016). We evaluated self-perceived body weight of the participants with their actual weight using the body mass index cut-off and grouped them by age: early adulthood (19-45), middle adulthood (46-59), and late adulthood (≥60). Logistic regression was conducted in each age group based on their weight misperception. The classification performance of the identified risk factors was evaluated with a bagging tree ensemble model with 5-fold cross-validation. RESULTS 22.2% (n=4,916) of the study participants incorrectly perceived their body weight, of which 14.1% (n=3,110) and 8.2% (n=1,806) were in the underestimated and overestimated groups. Among the age groups, the proportion of participants who misperceived their body weight was highest in late adulthood (31.8%) and the rate of overestimation was highest in early adulthood (14.1%). We found that a lower education level, absence of menopause, perception of themselves as unhealthy, and efforts for weight management were significantly associated with the overall misperception (overestimation or underestimation) of body weight across age groups. Based on the identified risk factors, the highest area under the receiver operating curve (AUROC) and accuracy of the best classification model (weight overestimation in all participants) were 0.758 and 0.761, respectively. Adding various associated lifestyle factors to the baseline model resulted in an average increase of 0.159 and 0.135 in AUROC for classifying weight underestimation and overestimation, respectively. CONCLUSIONS Age, education level, marital status, absence of menopause, amount of exercise, efforts for weight management (gain, loss, and maintenance), and self-perceived health status were significantly associated with the mismatch of body weight.

Abstract
INTRODUCTION Obesity affects more than one-quarter of adults in Saudi Arabia and is on the rise. A significant proportion of overweight and obese individuals misperceive their weight, and this misperception can affect their likelihood to exercise, consume healthy foods, or change unhealthy dietary habits. This study examines the prevalence of weight misperceptions in a national sample of Saudi adults and explores weight misperception association with sociodemographic factors, behavioral factors, and health status. METHODS This study was a nationwide cross-sectional survey conducted via phone interviews. A proportional quota sampling technique was used to obtain equal distributions of participants, stratified by age and gender, across the 13 regions of Saudi Arabia. Weight and height were self-reported, and obesity was determined as a BMI ≥30. Participants were asked to describe their current weight as ideal, underweight, overweight, or obese. Misclassification was then compared across groups according to a range of sociodemographic factors, behavioral risk factors, and health indicators. RESULTS Of the 6,239 participants contacted, 4,709 (75.5%) responded and completed the interview. Of them, 50.1% were female, and the mean age was 36.4 (SD ± 13.55) years. The majority (70.1%) of participants indicated having weighed themselves within the past 30 days. The prevalence of weight misperception in general was 42.0%, and in obese participants, it was 67.6%. In addition, a significant association was observed between weight misperception and obesity, age-group, educational level, diagnosed chronic condition, self-rated health, and sedentary lifestyle. There was no significant association between weight misperception and gender, physical activity, or a nutritional knowledge. CONCLUSIONS Weight misperception could be used as an indicator of a poor health routine that may lead to negative health outcomes.

Analysis of Health-Related Behaviors of Adult Korean Women at Normal BMI with Different Body Image Perceptions: Results from the 2013-2017 Korea National Health and Nutrition Examination Survey (KNHNES). INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E5534. [PMID: 32751821 PMCID: PMC7432878 DOI: 10.3390/ijerph17155534] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Revised: 07/22/2020] [Accepted: 07/28/2020] [Indexed: 12/31/2022]
Abstract
The tendency of misperceiving one's body image was found to be higher among those at normal body mass index (BMI). Thus, the present study aims to provide basic data to seek solutions for ideal physical activities and right body image perception by comparing health-related behaviors of women at normal BMI. Among the 39,225 respondents from the Korea National Health and Nutrition Examination Survey (KNHNES) conducted from 2013 to 2017, 10,798 adult women with World Health Organization (WHO) BMI Classifications of 18.5 ≤ BMI < 25 (Asia-Pacific) were considered, from which pregnant and breast-feeding women and women whose body image perception was not identified were excluded, leading to a total of 9288 women. Data were analyzed utilizing SAS ver. 9.4 for frequency analysis, cross tabulation, GLM (generalized linear model), and logistic regression analysis with complex samples design, in conformity with the guidelines of the KNHNES. The results showed that approximately most (87.6%) of adult Korean women misperceived their body image. Misperception of body image was related to inappropriate health-related behaviors such as smoking, insufficient sleeping, and excessive body weight management; those who had underestimated their body image (≤64 odds ratio (OR) (0.718 (confidence interval (C.I.) 0.594-0.866))) carried out fewer health-related behaviors, while women aged 65 or above engaged in more health-related behaviors when they perceived themselves as obese (OR 1.683 (C.I. 1.260-2.248; overestimation)). To sum up, it was found that lack of health management, inappropriate body weight control, and health-related behaviors are related to body image misperception compared with real BMI. As such, it is necessary to have educational programs to encourage building proper perception of one's body image and body weight, and to carry out health-related behaviors.

Abstract
BACKGROUND Overweight and obesity are an increasingly serious public health problem in Western societies, including Germany. The tendency of overweight and obese people not to classify themselves as such limits the efficacy of information on the health risks of these conditions and lessens the motivation to change behavior accordingly. In this article, we summarize the available study data on the selfperception of weight class. We present and discuss the differences between selfreported body-mass index (BMI) category and the actual category of the BMI when it is calculated from the individual's measured height and weight. METHODS We systematically searched the Medline, EMBASE, and Cochrane Library databases in August 2017 for pertinent publications. The study protocol was published in the PROSPERO register (CRD42017064230). Meta-analyses were calculable for a number of subgroup analyses. RESULTS A total of 50 studies from 25 countries were identified that contained findings on self-estimation of weight in a total of 173 971 study participants. The percentage of correct self-categorizations of BMI category varied from 16% to 83%, with marked heterogeneity of the population groups studied. In Europe, women overestimated their BMI category three times as often as men (RR: 3.22; 95% confidence interval: [2.87; 3.62], I2 = 0%). Most erroneous classifications were based on underestimates. Study participants of normal weight were more likely than others to categorize their BMI correctly. In European studies, 50.3-75.8% categorized their BMI correctly. Low socioeconomic status was associated with an incorrect perception of BMI. CONCLUSION The self-assignment of BMI categories is often erroneous, with underestimates being more common than overestimates. Physicians should take particular care to provide appropriate information to persons belonging to groups in which underestimating one's BMI is common, such as overweight people and men in general.

Abstract
Few health crises have been as predictable as the unfolding obesity pandemic. Clinical and public health services remain the front line of efforts to reduce the burden of obesity. While a range of clinical practice guidelines exist, the need for clinical interventions exceeds the capacity of health systems to provide care for those affected with obesity, and routine clinical practices fall far short of guidelines recommendations even in high-income countries. In this manuscript, we discuss current recommendations regarding obesity interventions and key challenges facing global health systems in managing the health needs of people with obesity. Improving the provision of obesity-related health care is a considerable challenge and will require changing existing perceptions of obesity as a matter of personal failure to its recognition as a disease, innovative approaches to health system reform, clinician capacity building and implementation support, a focus on prevention, and wise resource allocation. Leadership from governments, the medical profession, and patient and community groups to address the issues raised in this manuscript is urgently needed to address the growing health concern.

Abstract
While numerous studies have investigated body image, including body weight perception, most of which have focused on adolescents or young women, few studies have attempted to evaluate body weight perceptions in adult women according to age groups. This study was conducted to investigate the accuracy of self-perceived weight and actual body mass index (BMI) values among adult Korean women according to age. We used data from the 2016 Korean Study of Women's Health Related Issues, a population-based, nationwide, cross-sectional survey. BMI was calculated from self-reported weight and height. Participants were asked to describe their body image by choosing one of the following descriptions: very underweight, underweight, about right, overweight, or obese. The proportions of women aged 20-29, 30-39, 40-49, 50-59, 60-69, and 70-79 years who underestimated their body weight relative to their actual BMI category were 12.6%, 15.1%, 22.2%, 34.0%, 45.6%, and 50.7%, respectively; those who overestimated their body weight comprised 18.7%, 17.8%, 14.3%, 10.8%, and 7.4%. In all BMI categories, the proportion of those who overestimated their weight status increased as age decreased, while those who underestimated their weight status increased as age increased. After adjusting for possible covariates, age was strongly associated with both underestimation and overestimation. The odds ratio for underestimating one's weight status among women aged 70-79 yeas was 2.96 (95% CI: 2.10-4.18), and that for overestimation was 0.52 (95% CI: 0.35-0.79), compared to women aged 20-29 years. Age is the most important factor associated with weight perceptions among Korean women, affecting both underestimation and overestimation of weight status.

Abstract
BACKGROUND/OBJECTIVES Weight perception, especially misperception, might affect health-related quality of life (HRQoL); however, related research is scarce and results remain equivocal. We examined the association between HRQoL and weight misperception by comparing obesity level as measured by body mass index (BMI) and weight perception in Korean adults. METHODS Study subjects were 43 883 adults aged 19 years or older from cycles IV (2007-2009), V (2010-2012) and VI (2013-2014) of the Korean National Health and Nutrition Examination Survey. Multiple regression analyses comprising both logit and tobit models were conducted to evaluate the independent effect of obesity level as measured by BMI, weight perception and weight misperception on HRQoL after adjusting for demographics, socioeconomic status and number of chronic diseases. We also performed multiple regressions to explore the association between weight misperception and HRQoL stratified by BMI status. RESULTS Obesity level as measured by BMI and weight perception were independently associated with low HRQoL in both separate and combined analyses. Weight misperception, including underestimation and overestimation, had a significantly negative impact on HRQoL. In subgroup analysis, subjects with BMI ranges from normal to overweight who misperceived their weight also had a high risk of low HRQoL. Overestimation of weight among obese subjects associated with low HRQoL, whereas underestimation of weight showed no significant association. CONCLUSIONS Both obesity level as measured by BMI and perceiving weight as fat were significant risk factors for low HRQoL. Subjects who incorrectly perceived their weight relative to their BMI status were more likely to report impaired HRQoL, particularly subjects with BMI in the normal to overweight range. Based on these findings, we recommend political and clinical efforts to better inform individuals about healthy weight status and promote accurate weight perception.
