Date styles frequency out of obese, being obese and you can being obese category II and you may III ranging from 2006 and 2019

Time trends and you can projected prevalences from Bmi groups

A straightforward multinomial logistic regression design was used so you can assume the fresh frequency of every Body mass index classification throughout the years of 2006 due to 2030. That it design made certain the brand new frequency of all of the Body mass index classes can add up to 100% from year to year, and you may allows the brand new estimation out of a nonlinear development regarding prevalence regarding Bmi classes six . On top of that, they implicitly considers brand new group constitution of your own population as well as the products leading to Bmi change throughout the years (elizabeth.grams., use of ultra-junk foods and you will physical inactivity) 6 . Therefore, as opposed to education quoting the causal outcomes of exposures into the being obese exposure, education anticipating Body mass index throughout the years need no confounding handle six . Thus, all of our effortless multinomial logistic regression model provided merely Bmi group (oriented variable) and you may time (independent varying). Same methodological strategy has been used a previous study from estimated carrying excess fat during the You six .

Regression activities was held predicated on sex (men or women), age range (18–34, 35–54 otherwise ? 55 many years), race/pores and skin (light or blacks and other minority ethnicities), educational attainment (0–eight, 8–11 otherwise ? 12 many years of degree) and you may geographical devices (twenty six county capitals as well as the Federal Region) individually, as a result of the Vigitel take to weights. We checked out go out style (2006–2019) and you can estimated (2020–2030) frequency of each Bmi class, in addition to frequency from over weight (Bmi ? twenty-five kg/m dos ), obesity (Bmi ? 30 kilogram/meters dos ) and being obese categories II and III (Bmi ? thirty five kg/yards dos ).

Comparison away from anticipate accuracy

The precision of forecast model was analyzed via a simple multinomial logistic regression model to own Bmi classes (built changeable) and go out (separate changeable) out of 2006 to 2013. The latest predict frequency of each and every Bmi group of 2014 so you’re able to 2019 try estimated based on sex, and you can compared to the brand new corresponding noticed incidence regarding same season-sex. Design precision was measured via two metrics. Very first, we determined the fresh new publicity possibilities, where the 95% CI of each and every predict prevalence between 2014 and 2019 was in fact evaluated to determine whether they included the brand new seen incidence regarding same year-sex stratum. 2nd, i analyzed whether the difference in predict therefore the noticed prevalences try lower than ten% (10% cousin mistake).


Inside the 2006, brand new incidence off overweight, obesity and you may obesity kinds II and you can III in the Brazilian grownups have been 29.9%, 8.6%, and you will 3.2%, respectively. Within the 2019, the fresh prevalences attained thirty-five.1% to have fat, 14.6% to possess obesity and you may 5.7% to own obesity categories II and you will III (Fig. 1 and you will Table 1).

Date style and you may estimated frequency regarding body mass index classes inside Brazilian adults ranging from 2006 and you can 2030 based on sex.

Desk one time fashion prevalence regarding heavy, carrying excess fat, and you can being obese classes II and you can III during the Brazilian people anywhere between 2006 and 2019, centered on sociodemographic qualities.

The fresh prevalences out of obese, obesity and you will obesity groups II and you will III enhanced in all sociodemographic subgroups anywhere between 2006 and you may 2019 (Desk step 1). However, price and you may extent out-of weight gain ranged of the sex, age group, race/skin color and you may educational attainment. We seen a higher relative escalation in brand new incidence of heavy between 2006 and 2019 in females (Pr step 1.forty, 95% CI 1.35–1.45), young adults (Publicity 1.forty-eight, 95% CI step one.40–step one.57), blacks and other minority ethnicities (Public relations step 1.32, 95% CI step one.28–step one.37), and you will adults having 8–eleven many years of degree (Public relations dos.07, 95% CI step one.90–dos.25). Equivalent trend try noticed on upsurge in this new frequency away from obesity by the subgroups. To have being obese categories II and you may III, the latest relative boost in the same period was high when you look at the guys (Public relations 1.80, parhaat maat lГ¶ytää tyttГ¶ystГ¤vГ¤ 95% CI 1.44–dos.25), middle-old adults (Advertising 1.87, 95% CI step 1.56–2.24), blacks and other minority ethnicities (Publicity step one.97, 95% CI 1.70–dos.29), and you will grownups which have 8–eleven many years of training (Publicity 2.55, 95% CI dos.13–3.06). Absolute variations in this new prevalence of overweight, being obese and being obese categories II and you will II ranging from 2006 and you can 2019 are shown about Table step 1.
