A Momentary Lapse of Reason? Assessing the Pre- and Post-Brexit Preferences of UK Citizens

We analyze the persistence of the major determinants of distrust toward the European Union (EU) and pro-Brexit voting attitudes of citizens of the United Kingdom. Looking both backward and forward, our analysis confirms that Euroscepticism is deep-rooted, although the data reveal differences across different parts of the country. We observe no major transformation in the favor of the EU over the last two decades or in the post-referendum period. We also carry out an age-period-cohort analysis by interacting age and cohort effects with time to analyze the evolution of individual preferences. We find that an aging population will promote Eurosceptic assertiveness. We then implement a demographic forecasting analysis to predict whether the level of distrust of older cohorts can be offset by differing attitudes among younger cohorts in the future. On the contrary, we find that demographic trends will tend to strengthen distrust in the EU.

Gender-specific temporal trends in overweight prevalence among Chinese adults: a hierarchical age-period-cohort analysis from 2008 to 2015

Background As a key health risk, the prevalence of overweight has been strikingly increasing worldwide. This study aimed to disentangle the net age, period, and cohort effects on overweight among Chinese adults by gender. Methods Data came from the Chinese General Social Survey from 2008 to 2015, which was a repeated cross-sectional survey (n = 55,726, aged 18 and older). χ2 or t tests were used to estimate the gender disparities in overweight and socioeconomic status (SES). A series of hierarchical age-period-cohort cross-classified random-effects models were performed using SAS version 9.4 to estimate the overall and gender-specific temporal trends of overweight, as well as the association between SES and overweight. Further, a series of line charts were used to present the age and cohort variations in overweight. Results After controlling for covariates, significant age and cohort effects were observed among adults in China (b = 0.0205, p < 0.001; b = 0.0122, p < 0.05; respectively). Specifically, inverted U-shaped age effects were identified for both genders, with a high probability of overweight occurring in middle age (b = –0.0012, p < 0.001). Overweight was more prevalent among men than women before 60 years old, and this trend reversed thereafter (b = –0.0253, p < 0.001). Moreover, men born during the war (before 1950) and reform cohorts (after the 1975s) demonstrated a substantial decline in overweight, while men born in 1950–1975 showed an increasing trend in overweight prevalence (b = 0.0378, p < 0.05). However, the cohort effect on women was not statistically significant. Additionally, a higher SES was related to an elevated probability of overweight. Conclusion Gender-specific age and cohort effects on the prevalence of overweight were observed among Chinese adults. Both China and other developing countries need to pay attention to the coming obesity challenge and related health inequality. Full life-cycle overweight prevention interventions should focus on middle-aged adults, men born in the war and reform eras, and adults with a higher SES.
