Bmi Trajectory

Background. Whether there is heterogeneity in the development of BMI from middle-age onward is still unknown. The primary aim of this study is to analyze long-term obesity and how BMI trajectories are associated with health outcomes in midlife.Methods. Latent Class Growth Modelling was used to capture the changes in BMI over time. In this study, 3070 individuals from the National Population Health Survey (NPHS), aged 40–55 years at baseline, were included.Results. Four BMI trajectory groups, “Normal-Stable” (N-S), “Overweight-Stable” (OV-S), “Obese I-Stable” (OB I-S), and “Obese II-Stable” (OB II-S), were identified. Men, persons of White ancestry, and individuals who had no postsecondary education had higher odds of being in the latter three groups. Moreover, members of the OV-S, OB I-S, and OB II-S groups experienced more asthma, arthritis, hypertension, diabetes, heart disease, cognitive impairment, and reduced self-rated overall health. Individuals in the OB II-S group were at greater risk for back problems, chronic bronchitis or emphysema, and emotional issues when compared to the N-S group.Conclusion. Understanding different BMI trajectories is important in order to identify people who are at the highest risk of developing comorbidities due to obesity and to establish programs to intervene appropriately.

Bmi Trajectory

Knowledge regarding the heterogeneity of BMI trajectories is limited for the Canadian population. Using latent class growth modelling, four distinct BMI trajectories of individuals from young adulthood to middle age were identified for both women and men from the longitudinal data of the National Population Health Survey. The associations between BMI trajectories and the individuals’ sociodemographic characteristics and behavioural factors were also examined. Aboriginal women were found more likely to be in the long-term overweight or obese groups. It reveals that increased years of smoking, drinking, and being physically active were associated with lowering the BMI trajectory in all groups for both women and men, with some exceptions in the long-term normal weight group for men. Increased years of rural living, being employed, and living with low income were associated with raising the BMI trajectory in all groups for women and in some groups for men. Food insecurity was associated with raising the BMI trajectory in each group for both women and men.

Abstract Conceptualizing social isolation as a multidimensional construct encompassing social networks, social contacts, perceived support and loneliness, this research aims to: (1) identify patterns of social isolation trajectory among middle-aged and older adults in the U.S.; (2) investigate how different patterns of social isolation trajectory are related to adults’ physical, mental, cognitive, and overall health. Latent class growth modeling was used to examine social isolation trajectory patterns over nine years in a national sample of 6,457 adults aged 51+. Four patterns of social isolation trajectory were identified: severely isolated, moderately isolated, subjectively integrated, and objectively integrated. The objectively integrated group reported the best physical, mental, cognitive, and overall health, whereas the severely isolated group reported the worst. The moderately isolated and subjectively integrated groups fell in between, with the latter displaying relatively better health outcomes. Findings support a close relationship between poor health and long-term social isolation.

We aimed to identify leisure activity (LA) trajectories and examined the association among baseline characteristics, LA trajectories, and the later disability among older Taiwanese adults. Data were from the Taiwan Longitudinal Study on Aging Survey for the years 1996-2007 ( N = 3,186). LA trajectories were identified by using latent class growth curve modeling. Regression analyses were applied to predict the relationships among baseline characteristics, LA trajectories, and disability. Four LA trajectories—consistent high, consistent low, increasing, and decreasing—were identified. Lower depressive symptom was related to consistently active in LAs. Younger age and fewer comorbidities were related to develop an increasing LA trajectory. Participants in the consistent-high or increasing LA trajectories were more likely to be functionally independent, but those in the decreasing LA subgroup were more at risk of developing disability. The findings suggested that long-term changes in LA over time have benefits on physical health in older population.

Bmi Trajectory

Background. Asthma and obesity are two common health problems in the pediatric population. Obesity is associated with several comorbidities which are of great consequence. Excess adipose tissue has been linked to asthma in a number of studies. However, little is known about childhood body mass index (BMI) trajectories and the development of asthma phenotypes. Objective. The current study aims to investigate the significance of BMI trajectories over childhood and the risk of asthma phenotypes. Methods. The current study is a prospective cohort of children aged 0-2 years who were followed every two years for eight years through cycles one to five in the National Longitudinal Survey of Children and Youths (NLSCY). Statistical analysis: a latent class growth modelling (LCGM) method was used to identify BMI trajectory patterns from cycles one to five. Multiple imputation (number of imputations=5) was carried out to impute children with missing values on height or weight information. Sampling weights and 1,000 bootstrap weights were used in SAS PROC SURVEYLOGISTIC to examine the association between BMI trajectory and asthma phenotypes (persistent or transient asthma) in a multivariate analysis. Results. The study consisted of 571,790 males and 549,230 females. Among them, 46% of children showed an increasing trajectory in terms of change in BMI percentile during childhood, followed by the stable-trajectory group (41%) and decreasing-trajectory group (13%). After controlling for confounding factors, females in the increasing BMI trajectory group were four times more likely to be associated with persistent asthma (OR = 4.09; 95% CI:1.04-16.15; p = 0.0442) than females in the stable BMI trajectory group. No such relationship was found in males. The BMI trajectory was not significantly associated with risk of transient asthma for either sex. Conclusion. We report a female-specific association between increasing adiposity, measured by BMI, and persistent asthma.

Latent Class Growth

There is a lot of evidence that pre-birth employment and access to parental leave are important predictors of mothers’ labor market attachment after childbirth. This register-based study from Finland aimed to analyze in which ways the type of job contract (none, temporary, or permanent) at the start of maternity leave predicts labor market attachment in the long term. The mother cohorts were followed up for 11 years. Labor market attachment was analyzed with latent class growth analysis, which makes it possible to identify subgroups with differing track and level of development. Lack of employment and having a temporary contract at baseline were associated with slower and weaker labor market attachment irrespective of mother’s age, socioeconomic status, and subsequent births. These findings suggest that the polarization of women into the core and periphery of the labor market structure tends to continue after the birth of the first child. Temporary employment might be an obstacle for having rights for a job-protected family leave and have long-term consequences on the continuity of employment and the division of paid and unpaid work in the family.
