Attenuation was similar, but less marked, when adjusting for current and life course smoking, with the exception of associations with proinsulin and leptin which were slightly strengthened by adjustment for current smoking status.
Results using multiple imputation were similar to those using complete case analysis (Supplementary Table 4), except that associations between socioeconomic position, interleukin-6 and proinsulin were still apparent after adjustment for current and life course body mass index.
The effects of adjustment for current and life course body mass index and cigarette smoking of these associations between socioeconomic position and novel CHD risk factors are shown in Table 4.
Adjustment for current and life course body mass index attenuated the associations observed between socioeconomic position and four CHD risk factors (C-reactive protein, interleukin-6, proinsulin and leptin); only the association between socioeconomic position and C-reactive protein remaining statistically significant (Table 4).
Most studies of marital status and health or mortality in older age groups have considered only current marital status and so ignore life course and accumulated benefits and risks of marital status trajectories.
According to this perspective, combinations, accumulations and/or interactions of social environments and biological insults experienced throughout the life course impact on current and future health and oral health conditions [ 13].
Subsequent level 2 and 3 life course factors in terms of current breastfeeding and current oral hygiene (visible plaque) were entered into step II and III, respectively.
Guided by a life course developmental perspective, the current study used a subsample of American Indians (n = 927) from the National Longitudinal Study of Adolescent Health Add Healthh) to explore alcohol use (current drinking, usual number of drinks, and binge drinking) among this population.
In the following, we first present a short review of current studies, then show the necessity of qualitative and life course perspectives.
This phenomenon has been observed in children, but we are not aware of any current evidence for whether this process continues over the adult life course.
