To determine the prevalence of high weight at different characteristics, understand the perceptions and behaviours towards high body weight, and determine potential influencing factors of body weight misperception among high-weight adults in Jilin Province.
A cross-sectional survey with complex sampling design was conducted. We described the prevalence and perception of high body weight.
Northeast China in 2012.
Adults (n 20 552) aged 18–79 years.
Of overweight individuals, 37·4 % considered themselves as ‘normal weight’, 4·8 % reported themselves as being ‘very thin’ and only 53·1 % were aware of their own weight being ‘overweight’. About 1·8 % of both male and female obese individuals perceived themselves as ‘very thin’. Only 29·1 % of obese people thought of themselves as ‘too fat’. Nearly 30·0 % of centrally obese men and women perceived that their waist circumference was about right and they were of ‘normal weight’; 5·7 % of the centrally obese even perceived themselves as being ‘very thin’. Only 51·8 and 12·5 % of centrally obese individuals reported themselves to be ‘overweight’ or ‘too fat’. Body weight misperception was more common in rural residents (OR; 95 % CI: 1·340; 1·191, 1·509). The prevalence of body weight misperception increased with age (middle age: 1·826; 1·605, 2·078; old people: 3·101; 2·648, 3·632) and declined with increased education level (junior middle school: 0·628; 0·545, 0·723; senior middle school: 0·498; 0·426, 0·583; undergraduate and above: 0·395; 0·320, 0·487).
Body weight misperception was common among adults from Jilin Province.
In China, rapid economic growth and increasing social problems constitute the two basic characteristics underlying contemporary social change. With dramatic social change, loneliness in older adults may have changed across birth cohorts, thus altering older adults’ mental health. The present study aims to identify birth cohort changes in Chinese older adults’ loneliness and the social indicators underlying these changes.
Cross-temporal meta-analysis was utilized to investigate changes in Chinese older adults’ loneliness from 1995 to 2011. We analyzed 25 studies (N = 13,280 adults; age ≥ 60 years) employing the University of California at Los Angeles Loneliness Scale. We correlated loneliness scores with social indicators and matched these correlations for three periods: ten years before the data collection, five years before data collection, and during the year of data collection.
Loneliness levels in Chinese older adults have increased by 1.02 standard deviations from 1995 to 2011. Social indicators such as increased urbanization level, personal medical expenditure, divorce rate, the Gini coefficient, and unemployment rate significantly predicted loneliness in Chinese older adults. Decrease in social connectedness and increase in levels of health threat may be responsible for the observed increase in levels of loneliness.
Cross-temporal meta-analysis revealed a birth cohort increase in loneliness among Chinese older adults. We conclude that changes in social connectedness and levels of health threat likely play an important role in predicting loneliness in the population of Chinese elderly adults.
