All analyses was presented using new state-of-the-art questionnaire build routines of Stata analytical software package adaptation 12. We estimated weighted prevalences out of being obese by 12 months and you can within this seasons from the kinds of sociodemographic predictors. Being obese prevalences was indeed compared of the degrees of for every associate into access to Rao–Scott ? dos examination and you may examination to possess linear trend to have nominal and you may ordinal predictors, respectively; accounting with the complex questionnaire construction. I estimated adjusted incidence rates off obesity by the quantities of sociodemographic predictors inside every year of your survey, through the use of multivariable Poisson regression designs to your log-hook up and you may strong estimates away from variance. In the long run, we looked at the change within the carrying excess fat frequency out-of 2005 so you can 2010 total and also by degrees of sociodemographic parameters from the quoting adjusted prevalence distinctions (PD) and you can 95 % confidence menstruation inside the multivariable Poisson regression designs. To determine whether or not alterations in being obese incidence out of 2005 in order to 2010 differed significantly ranging from quantities of sociodemographic predictors, i examined cross-device (interaction) words anywhere between 12 months and you may types of each predictor to the use of adjusted Wald evaluation.

*Letter is the complete test frequency per class. In 2005, fifteen some body plus 2010, twenty-9 individuals got missing thinking having relationship status and you can have been omitted from the detailed analytics out-of , 2063 somebody got shed opinions to own dinner insecurity and was in fact excluded about detailed analytics out of eating insecurity.
‡P thinking are from the brand new Rao–Scott ? dos sample to own sex, relationship status, urban/rural and you can region. To have many years, food safety and you can wide range index, P thinking depict an examination getting trend out-of unadjusted Poisson regression designs with carrying excess fat while the lead and a variable representing kinds of your own ordinal associate since the a continuous predictor.
Performance
Suggest Body mass index from inside the 2005 and 2010 are 25·dos ( se 0·1) kg/yards 2 and you can twenty-five·eight ( se 0·0) kg/yards dos , respectively; the essential difference between many years was 0·5 kilogram/yards dos (95 % CI 0·cuatro, 0·six kg/m 2 ). There were no big changes in the proper execution of one’s Bmi shipping within survey ages full otherwise by the sex (Fig. 1). Incidence regarding obesity within the 2005 and you may 2010 try thirteen·9 ( se 0·3) % and 16·cuatro ( se 0·2) %, correspondingly. The brand new PD are 2·seven % (95 % CI 1·nine, 3·cuatro %).

In both years, the new incidence from carrying excess fat are highest in women, participants old 55–64 ages, men and women without dinner insecurity or who have been about highest quintiles of your wide range directory, and people surviving in urban areas or perhaps in the latest National Regions area (Table step one). Any of these associations differed anywhere between female (on line secondary matter, Extra Table 2) and you can dudes (online additional matter, Supplemental Table 3). For example, the positive connectivity of riches list and dinner cover which have being obese in both questionnaire ages have been stronger in guys than simply women. Similarly, the greater incidence out-of carrying excess fat inside the metropolitan in contrast to rural section both in questionnaire decades is noticeable into the guys however during the women.
In these models, modifications details integrated sex, age, marital condition, eating protection, wealth, urbanicity and area for home, classified predicated on Desk 1
2nd, we tested the latest contacts of sociodemographic affairs and you can frequency out of being obese from inside the for Dansk kvinder dating hjemmeside each questionnaire season shortly after modifying getting potential confounding (Table dos). In both age, obesity is definitely associated with the feminine sex, many years, and you can located in new Pacific or Federal Territories countries. Whereas in 2005 the fresh relationship out of wide range which have being obese adopted an excellent dose–reaction gradient, this year the newest prevalence regarding obesity are similarly large for the wealth quintiles dos to 5 as compared with a low quintile. By contrast, if you find yourself surviving in rural section (quick outlying communities or distribute outlying components) wasn’t related to the newest incidence off being obese into the 2005, it was of this a lesser prevalence in contrast to cities this present year.
