Weight underestimation for adults in Beijing and its association with chronic disease awareness and weight management

Perception of a need to change weight in individuals living with and beyond breast, prostate and colorectal cancer: a cross-sectional survey

PURPOSE

People living with and beyond cancer (LWBC) are advised to achieve a body mass index (BMI) within the healthy range (≥ 18.5 and < 25). Not perceiving a need for weight change may be a barrier to achieving a healthy weight. This study aimed to explore factors associated with perceived need for weight change among people LWBC.

METHODS

Adults diagnosed with breast, prostate, or colorectal cancer were recruited through National Health Service sites in Essex and London. Participants (N = 5835) completed the 'Health and Lifestyle After Cancer' survey, which included a question on perceived need to change weight. Associations between perceived need for weight change and BMI, and perceived need for weight change and health and demographic variables, were analyzed using chi-square tests and logistic regression, respectively.

RESULTS

The proportion of participants perceiving a need to lose weight differed according to BMI category: healthy weight (23%), overweight (64%), obese (85%) (P < 0.001). Having overweight or obesity but not perceiving a need to lose weight was associated with being older, male, non-white, not married or cohabiting, and having cancer that had spread, no formal qualifications, no comorbidities, and having received chemotherapy.

CONCLUSIONS

Perceived need to lose weight is prevalent among people LWBC with obesity and overweight. This group may be interested in weight management support. Demographic and health factors were associated with having obesity or overweight but not perceiving a need to lose weight.

IMPLICATIONS FOR CANCER SURVIVORS

Weight loss interventions for people LWBC are needed. A subset of people LWBC with overweight and obesity may need additional information or motivators to engage with weight management.

Trends in prevalence of overweight and obesity, self-perceived overweight or obesity, and weight loss efforts among older adults in South Korea, 2005-2021

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.

Weight self-misperception and obesity-related knowledge, attitudes, lifestyle behaviours and cardio-metabolic markers among Chinese school-aged children and adolescents

OBJECTIVE

The relationships between childhood weight self-misperception and obesity-related factors particularly health markers have not been extensively discussed. This study aims to examine the associations between weight self-misperception and obesity-related knowledge, attitudes, lifestyles and cardio-metabolic markers among Chinese paediatric population.

DESIGN

Cross-sectional study.

SETTING

Data sourced from a national survey in Chinese seven provinces in 2013.

PARTICIPANTS

Children and adolescents aged 5-19 years.

RESULTS

Of the total 14 079 participants, there were 14·5 % and 2·2 % participants over-estimated and under-perceived their weight, respectively. Multi-variable logistic regression was applied to calculate OR and 95 % CI (95 % Cl) of obesity-related behaviours and cardio-metabolic markers by actual and perceived weight status. Individuals who perceived themselves as overweight/obese were more likely to have prolonged screen time, insufficient dairy intake and over sugar-sweetened beverages consumption (all P < 0·05), regardless of their weight. Furthermore, actual overweight/obese individuals had higher odds of abnormal cardio-metabolic markers, but a smaller magnitude of association was found among weight under-estimators. Among non-overweight/obese individuals, weight over-estimation was positively associated with abdominal obesity (OR: 10·49, 95 % CI: 7·45, 14·76), elevated blood pressure (OR: 1·30, 95 % CI: 1·12, 1·51) and dyslipidemia (OR: 1·43, 95 % CI: 1·29, 1·58).

CONCLUSIONS

Weight over-perception was more prevalent than under-estimation, particularly in girls. Weight over-estimators tended to master better knowledge but behave more unhealthily; both weight over-perception and actual overweight/obesity status were associated with poorer cardio-metabolic markers. Future obesity intervention programmes should additionally pay attention to the population with inaccurate estimation of weight who were easily overlooked.

Awareness, treatment, control, and determinants of dyslipidemia among adults in China

Effective management of dyslipidemia is important. This study aimed to determine the awareness, treatment, control, and determinants of dyslipidemia in middle-aged and older Chinese adults in China. Using data from the 2015 China National Stroke Screening and Prevention Project (CNSSPP), a nationally representative sample of 135,403 Chinese adults aged 40 years or more were included in this analysis. Dyslipidemia was defined by the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults final report (NCEP-ATP III) and the 2016 Chinese guidelines for the management of dyslipidemia in adults. Models were constructed to adjust for subjects’ characteristics with bivariate and multivariable logistic regression analyses. Overall, 51.1% of the subjects were women. Sixty-four percent were aware of their condition, of whom 18.9% received treatment, and of whom 7.2% had adequately controlled dyslipidemia. Dyslipidemia treatment was higher in men from rural areas than their urban counterparts. The multivariable logistic regression models revealed that women, urban residents, and general obesity were positively related to awareness. Women, married respondents, and current drinkers had higher odds of treatment. Age group, overweight, general obesity, urban residence, and women were independent determinants of control. Dyslipidemia awareness rate was moderately high, but treatment and control rates were low. Results can be used to develop policies and health promotion strategies with special focus on middle-aged and older adults.

Weight self-perception in adolescents: evidence from a population-based study

OBJECTIVE

To evaluate weight misperception among adolescents and determine associations between self-perceived weight and socio-demographic characteristics, BMI, screen time, self-rated food quantity and diet quality, weekly frequency of breakfast and the consumption of healthy and unhealthy foods.

DESIGN

A cross-sectional, two-stage, probabilistic population-based study was conducted in Campinas, Brazil. Multinomial logistic regressions were run to estimate weight self-perception.

SETTING

Data from the Campinas Health Survey (ISACamp) and Campinas Food Consumption Survey (ISACamp-Nutri).

PARTICIPANTS

A total of 911 adolescents aged 10-19 years.

RESULTS

Nearly half (47·7 %) of the adolescents with overweight/obesity did not evaluate their weight properly. Weight self-perception as thin and excess weight was associated with the female gender, overweight/obesity, self-rated diet quality as poor/very poor and eating snacks ≥3 times/week. Adolescents who did not consume breakfast daily were less likely to perceive themselves as thin. Adolescents who ate excessively were more likely and those who consumed cookies/crackers ≥3 times/week were less likely to perceive themselves as having excess weight.

CONCLUSIONS

Greater weight misperception was found in overweight/obese adolescents. Gender, BMI, self-rated food quantity/diet quality, weekly frequency of breakfast and some unhealthy foods were associated with self-perceived weight. The present findings could contribute to health promotion strategies targeting adolescents.

Orthopaedic patients underestimate their body weight too: a cross-sectional study

INTRODUCTION

The relation between a large body mass and comorbidity, certain types of cancers and musculoskeletal disorders has been extensively documented. However, a high proportion of overweight patients appears unaware of the medical risks of their condition and frequently underestimates their body weight. This observation is prevalent across numerous medical specialties and settings.

METHODS

This study analysed the misperception of obesity status in a cohort of 1137 patients attending an orthopaedic clinic by means of self-completed questionnaires and objective biometrics.

RESULTS

Patients displayed a poor estimation of the self-body mass index (34.6%), especially among larger individuals, with 45.15% of pre-obese and 21.17% of obese patients previously attempting weight-loss. A direct association between low educational achievement and obesity rates was observed in orthopaedic patients.

DISCUSSION

Obesity is a well-known contributor to many conditions, including musculoskeletal diseases. Despite this association, many obese patients consider their body mass as normal. Misperception of self-body weight has been documented in many medical specialities, and this study confirms the same scenario in orthopaedic patients.

CONCLUSION

The association between self-image distortion and obesity observed in this study may assist in the evaluation and management of obesity cases in orthopaedic clinics.

Weight underestimation linked to anxiety and depression in a cross-sectional study of overweight individuals in a Sami and non-Sami Norwegian population: the SAMINOR Study

OBJECTIVES

Underestimation of overweight/obesity may prevent weight loss attempts, resulting in further weight gain and maintenance of overweight. Mental health benefits may nevertheless surpass negative consequences. Our main objective was to study the association between underestimation of overweight/obesity and symptoms of anxiety and depression in Sami and non-Sami populations.

DESIGN

Population-based cross-sectional study.

SETTING

The SAMINOR 2 Clinical Study with participants from 10 municipalities in Northern Norway enrolled between 2012 and 2014.

PARTICIPANTS

The study included 3266 adults of multiethnic rural origin with overweight/obesity (body mass index (BMI) ≥25 kg/m²) whereof 1384 underestimated their weight (42%).

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary outcome measure was symptoms of anxiety and depression and secondary outcome measures were BMI and the demographic variables: sex, age, education and marital status.

RESULTS

A higher proportion of Sami men compared with non-Sami men were obese, and reported more symptoms of anxiety and depression. More men than women, and a higher proportion of Sami women compared with non-Sami women, underestimated their weight. Multivariable-adjusted analyses showed that women were less likely to underestimate their weight compared with men (OR 0.43, 95% CI 0.33 to 0.55 in Sami and OR 0.33, 95% CI 0.26 to 0.42 in non-Sami), higher BMI was protective against weight underestimation (OR 0.72, 95% CI 0.69 to 0.75 in Sami and OR 0.63, 95% CI 0.60 to 0.67 in non-Sami), slightly higher odds of weight underestimation were observed with increasing age in both ethnic groups (OR 1.03, 95% CI 1.01 to 1.05 in Sami and OR 1.02, 95% CI 1.00 to 1.03 in non-Sami), while higher education lowered the odds in non-Sami (OR 0.69, 95% CI 0.55 to 0.87). Weight underestimation was protectively associated with anxiety and depression in Sami men (OR 0.48, 95% CI 0.27 to 0.84) and in non-Sami women (OR 0.44, 95% CI 0.25 to 0.78) adjusted for age, BMI, education and marital status.

CONCLUSIONS

Independent of ethnicity, more men than women underestimated their weight. Underestimation of weight was protectively associated with anxiety and depression in Sami men and non-Sami women.

Effect of maternal weight gain according to the Institute of Medicine recommendations on pregnancy outcomes in a Chinese population

Objective

This study aimed to analyze the effects of maternal weight on adverse pregnancy outcomes.

Methods

Data were retrospectively collected from a hospital in Wuhan, China. A total of 1593 pregnant women with singletons were included. Adverse outcomes during pregnancy, such as small for gestational age (SGA), large for gestational age (LGA), and hypertensive disorders in pregnancy (HDP) were analyzed.

Results

The risks of low birth weight, SGA, and preterm birth were significantly higher in the inadequate gestational weight gain (GWG) group compared with the adequate GWG group. GWG over the guidelines was related to a higher risk of macrosomia, LGA, cesarean section, and HDP than GWG within the guidelines. The risks of low birth weight (OR = 5.082), SGA (OR = 3.959), preterm birth (OR = 3.422), and gestational diabetes mellitus (OR = 1.784) were significantly higher in women with a normal pre-pregnancy body mass index (BMI) and inadequate GWG compared with women with a normal pre-pregnancy BMI and adequate GWG. The risks of macrosomia (OR = 3.654) and HDP (OR = 1.992) were increased in women with normal pre-pregnancy BMI and excessive GWG.

Conclusion

Women with an abnormal BMI and inappropriate GWG have an increased risk of adverse maternal and infant outcomes. Weight management during the perinatal period is required.
