Intergenerational relationships between the smoking patterns of a population-representative sample of US mothers and the smoking trajectories of their children.

ABSTRACT: We assessed intergenerational transmission of smoking in mother-child dyads.We identified classes of youth smoking trajectories using mixture latent trajectory analyses with data from the Children and Young Adults of the National Longitudinal Survey of Youth (n = 6349). We regressed class membership on prenatal and postnatal exposure to maternal smoking, including social and behavioral variables, to control for selection.Youth smoking trajectories entailed early-onset persistent smoking, early-onset experimental discontinued smoking, late-onset persistent smoking, and nonsmoking. The likelihood of early onset versus late onset and early onset versus nonsmoking were significantly higher among youths exposed prenatally and postnatally versus either postnatally alone or unexposed. Controlling for selection, the increased likelihood of early onset versus nonsmoking remained significant for each exposure group versus unexposed, as did early onset versus late onset and late onset versus nonsmoking for youths exposed prenatally and postnatally versus unexposed. Experimental smoking was notable among youths whose mothers smoked but quit before the child's birth.Both physiological and social role-modeling mechanisms of intergenerational transmission are evident. Prioritization of tobacco control for pregnant women, mothers, and youths remains a critical, interrelated objective.

Project description:BackgroundViolence and other adversities commonly co-occur, yet are usually investigated individually. The primary objectives of this paper are to investigate: (i) the relationship between maternal exposure to violence (including childhood abuse and intimate partner violence) and postpartum mental and physical health; and (ii) the extent to which exposure to violence and poor maternal mental and physical health are associated with children's emotional-behavioral difficulties.MethodsProspective pregnancy cohort (n = 1507) followed up to 4 year postpartum. Validated measures used: Composite Abuse Scale; Edinburgh Postnatal Depression Scale, SF-36, Child Maltreatment History Self Report; Strengths and Difficulties Questionnaire. Logistic regression was used to investigate associations between maternal childhood abuse, intimate partner violence (IPV), maternal health and child emotional and behavioral difficulties at age 4.OutcomesTwo out of five women (41%) reported abuse in childhood, and almost one in three (29%) reported IPV during the first four years of motherhood. Women reporting both physical and sexual childhood abuse had markedly raised odds of IPV and poor physical and mental health at all time points (pregnancy, first year postpartum and four year postpartum). For the index child, violence exposures (maternal childhood abuse or IPV) and poor maternal physical or mental health were associated with higher odds of emotional/behavioral difficulties at age four. In multivariable models (adjusted for child gender and maternal age), cumulative exposures (multiple violence exposures or poor maternal mental or physical health at multiple time points) each independently added to increased odds of emotional-behavioral difficulties. Children of mothers who reported a history of childhood abuse but were not exposed to IPV had odds of difficulties similar to children of mothers not reporting any violence exposure, suggesting resilient outcomes where violence experiences are not repeated in the next generation.InterpretationThe clustering of risk (child and adult violence experiences) and the accumulation of risk within families (IPV, poor maternal health, child difficulties) highlight the need for effective early intervention to limit or ameliorate the impact of violence across the lifespan, and to break the intergenerational cycle of disadvantage.

Project description:BackgroundResearchers are increasingly acknowledging the importance of understanding patterns of engagement in multiple, as opposed to isolated, health behaviours. Accordingly, several studies, targeting various geographical regions, have begun to identify and characterize unique classes of individuals in terms of their engagement in health behaviours, towards gaining insights that might guide tailored health interventions. Our study extends this stream of research to the Israeli context, as well as examines whether certain sociodemographic characteristics tend to be associated with affiliation to a specific group of individuals, i.e., class membership.MethodsTwo large representative samples were obtained from the 2010 and 2017 National Social Surveys of the Israel Central Bureau of Statistics. Latent Class Analysis was used to identify different classes, based on levels of engagement in five health behaviours: fruit-and-vegetable consumption, physical activity, smoking avoidance, sleep, and influenza vaccination. Multinomial logistic regression was applied to test the associations between sociodemographic characteristics (age, gender, religion, education level) and class membership.ResultsWe identified three distinct classes (denoted "healthy", "unhealthy", and "mixed"). Overall, the "healthy" class was characterized by healthy levels of fruit-and-vegetable consumption and physical activity, a low rate of currently-smoking individuals, and a high proportion of influenza vaccination. The "mixed" class was characterized by healthy levels of fruit-and-vegetable consumption and sleep duration, moderate levels of physical exercise, a high proportion of currently light smokers, and a low rate of vaccination. The "unhealthy" class was marked by relatively low levels of engagement in health behaviours. Generally, older, Jewish, and more-educated individuals were more likely to belong to the "healthy" class, while young, non-Jewish, and less-educated individuals were more likely to belong to the "unhealthy" class. We further identified differences between the 2010 and 2017 samples (e.g., differences in men's likelihood of being in the "unhealthy" class), suggesting that some behavioural patterns might have changed over time.ConclusionThis research identified three classes of engagement in health behaviours across two large and representative samples. Moreover, the classes were associated with unique sociodemographic characteristics. Consequently, our findings can highlight health-behavioural patterns relevant to different sub-populations that should be considered in public health interventions.
