Aiming to further explore possible underlying causes of the recent remarkable stagnation and relative decline in American heights, this paper describes the result of analysis of the commercial US Sizing Survey (2002). Heights are correlated positively with income and education among both white males and females while Body Mass Index (BMI) is correlated negatively among females, as in other samples. In contrast to much of the literature, this paper considers geographic correlates of height such as local poverty rate, median income and population density at the zip code level of resolution. After adjusting for confounding factors that influence height such as income and education, population density is found to be strongly and negatively correlated with height among white men, but less so among white women. The effect on BMIs less convincing. Other ethnic groups are not analysed in detail because of the small number of observations available. Local economic conditions as measured by median income, unemployment and poverty rate do not have a strong correlation with height or BMI after adjusting for individual income and education.

Despite the vast literature on the socioeconomic status (SES) gradient of obesity among adult people, no study has investigated the relationship between institutional power and body mass index. Using national survey data from the "China Labor-force Dynamics Survey 2016" (CLDS 2016), multistage cluster-stratified probability proportional to size (PPS) sampling was employed to select cases from 29 provinces, cities, and autonomous regions in China. This study adopts an institutional approach to explore the influences of SES and institutional power on the state of being overweight or severely overweight (obese) among Chinese adults. It is shown that SES has a non-linear influence on being overweight or obese, higher education has a negative effect on being overweight or obese, income has an inverted U-shaped effect on being overweight or obese, and having a managerial or administrative job has a positive effect on being overweight but less so on obesity. These findings reveal that disparities in health outcome and risks are due to inequality in SES. The work unit is a stronger predictor of adults being overweight or obese than occupation. Working in the public sector has a positive effect on being overweight relative to working in the private sector, and only state institutions and government departments have a positive association with obesity. Our results indicate that institutional structure still has effects on individuals' life chances in the era of China's market transition.

SummaryBody mass index (BMI) is the 'measuring rod' of nutritional status. This study investigates the type and extent of correlation between adult male BMI and socioeconomic, cultural and bio-demographical variables using data from 11,496 individuals from 38 districts of Central India. For each individual, stature, body weight and sitting height data were collected, their Cormic index and BMI computed, and averages for each district calculated. Mean BMI was found to be lowest for the population of Tikamgarh (17·90±1·91 kg m−2) and highest for that of Durg district (19·33±2·16 kg m−2), whereas the mean BMI for the total population of Central India was 18·67±2·18 kg m−2, which is lower than that of well-to-do individuals in India as a whole. The F ratio indicates that there is inter-district variation in anthropometric characteristics of populations. District-wise biosocial indicators were obtained, namely population density per square kilometre, percentage urban population, percentage of population that is of scheduled caste/tribe, sex ratio, average rural population per PHC/CHC (primary or community health centre), literacy rate, life expectancy, total fertility rate, infant mortality rate, gender development index and human development index. Most of these variables were found to be significantly correlated with each other, but BMI was only significantly correlated with three of them, viz. gender development index (R2=0·211), life expectancy (R2=0·130) and infant mortality rate (R2=0·128). Gender development index and life expectancy were positively correlated with BMI, whereas infant mortality rate was negatively correlated. It is concluded that if BMI increases then life expectancy will also increase. Thus better nutritional status may be a helpful tool for reducing infant mortality rate, which is an indicator of socioeconomic status, health condition, health care and ultimately overall development of a region or population.

The influence of smoking and body mass index on wound dehiscence and long term recurrence rate of primary excised pilonidal sinus The study analyses the influence of lifestyle issues smoking and obesity on postoperativ wound dehiscence and long term recurrence rate of primary excised presacral pilonidal sinus. A database of 1.968 patients of three german military hospitals treated by excision and primary midline closure or excision and open granulation between the years of 1980 and 1996 was systematically analysed retrospectively. Long term recurrence rate was coupiled by a standard telephone interview of 534 patients randomized from the above mentioned group. The average interview took place 14,2 years following surgery (confidence intervall 7,4- 25,4 years). Most patients were male (m:f, 533:1). At the time of first treatment the average age of the patients was 22,9 years. 34 percent of the patients were non-smokers. The mean body mass index was 25 kg/m². The obesity group showed dehiscences in 21 percent, whereas the normal weight patients had dehiscences in 19,5 percent. There was no statistically significant difference (p = 0,9). Comparing the dehiscences found in smokers versus non-smokers there was no statistically significant difference (p = 0,34). Recurrences could be seen in the whole time of long-term-follow-up of 25 years, especially in the first five years, independent of smoking and weight. There was also no significant difference between long term recurrence rate of smokers and non-smokers. Obese patients compared to normal and underweighting patients presented a minimal lower recurrence rate, but the difference was not significant. It has to be concluded that there is no significant influence of smoking and body mass index on the long term recurrence rate and the wound dehiscence rate of primary pilonidal sinus treated ether with midline closure or primary open treatement in the analysed military population studied. There must be other reasons for the increasing incidence of pilonidal sinus in ...

The correlation between evening type, body mass index (BMI), and obesity has attracted the attention of researchers. In this study, I surveyed a sample of adults drawn from the general population in the US to examine whether or not evening types have a higher BMI than do other chronotypes
and whether or not they are more likely than other chronotypes to become obese. I also proposed a personality-based explanation of the relationship between BMI, evening type, and obesity, with self-control as the mediator. As hypothesized, I found that evening types had a higher BMI and were
more likely to be obese than were either morning types or intermediate types. The finding that the positive relationship between eveningness and BMI can be completely mediated by self-control is most significant.

This study uses fixed-effects regression modeling and three waves of data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine whether union status and educational attainment interact to influence change in body mass index (BMI) during emerging adulthood. The results support the hypothesis that the effect of union status on change in BMI is smaller for those with more educational attainment. In particular, emerging adults with no college education experience significant increases in BMI associated with both marriage and cohabitation. The increases in BMI associated with marriage and cohabitation are significantly smaller for those with some college education—but are still somewhat present. Among emerging adults with college degrees, however, involvement in cohabitation/marriage is not associated with increases in BMI at all. Potential explanations for this pattern of results and suggestions for future research are discussed.

The objective of the current study was to investigate the heritability of breast size and the degree to which this heritability is shared with BMI. In a sample of 1010 females twins (mean age 35 years;SD= 2.1; range 28–40), self-report data pertaining to bra cup size and body mass index (BMI) was collected in the context of self-report data and an interview relating to disordered eating respectively. In a sample of 348 complete twin pairs who completed data collection (226 MZ pairs and 122 DZ pairs and 360 incomplete pairs (170 MZ and 190 DZ)), we found that the heritability of bra cup size was 56%. Of this genetic variance, one third is in common with genes influencing body mass index, and two thirds (41% of total variance) is unique to breast size, with some directional evidence of non-additive genetic variation. The implications of these findings with respect to previous research linking breast size with reproductive potential are discussed.
