Parent Nativity and Child Asthma Control in Families of Mexican Heritage: The Effects of Parent Depression and Social Support.

ABSTRACT:

Objective

Research has repeatedly demonstrated that parent foreign nativity has a protective effect on child asthma outcomes among Mexican Americans, but the mechanisms underlying this relationship are not well understood. The current study explored parent depression as a mediator and social support as a moderator of the parent nativity-child asthma control pathway.

Methods

Data come from the baseline sample of a trial (NCT02481986) testing community interventions for 223 children aged 5 to 16 with uncontrolled asthma. We focused on parent/child dyads of Mexican heritage (N = 165; mean age = 9.08, standard deviation = 2.94; 57.3% with Mexico-born parent). Asthma control was defined using the child and adult versions of the Asthma Control Test (ACT). Psychosocial factors included parent depression symptoms and social (instrumental, informational, and emotional) support.

Results

Mexican-born parents had fewer depressive symptoms (β^ = -2.03, SE^ = 0.24) and children with better asthma control (β^ = 1.78, SE^ = 0.24) than US-born parents, P < .0001. Analyses suggested partial mediation of the nativity-ACT path via parent depression (P < .001). An interaction between Instrumental Support and Nativity was marginally significant (β^ = -0.10, SE^ = 0.05, P = .07), with protective effects only observed at higher support levels. Last, among Mexico-born parents, the protective nativity effects on ACT declined with increasing residential years in the United States through 12 years.

Conclusions

This study is novel in identifying parent depression as one mechanism underlying the effects of parent nativity on child asthma control, but results suggest that the health advantages may depend on availability of support. Providing resources for parent depression and instrumental support (transportation, childcare) can optimize asthma interventions in this population.

Project description:BackgroundStudies investigating dietary resemblance between parents and their children have gained mixed results, and the resemblance seems to vary across nutrients, foods, dietary-assessment tools used, and parent-child pairs. We investigated parent-child dietary resemblance using a novel approach in applying statistical analysis, which allowed the comparison of 'whole-diet' between parents and their children. Additionally, we sought to establish whether sociodemographic factors or family meals were associated with dietary resemblance and whether parent-child dietary resemblance was dependent on the parent providing food consumption data on behalf of the child (father or mother, "the respondent").MethodsThe DAGIS study investigated health behaviors among Finnish preschoolers using a cross-sectional design. One parent filled in a food frequency questionnaire (FFQ) measuring the child's food consumption outside preschool hours during the last week. In addition, we instructed both parents or legal guardians, should the child have two, to fill in a similar FFQ regarding their own food use. Parents also reported their educational level, the number of children living in the same household, and the number of family meals. As a measure of dietary resemblance between a parent and a child, we computed Spearman correlations ranging mostly from no resemblance (0) to complete resemblance (+ 1) between parent-child pairs over the 'whole-diet' (excluding preschool hours). These resemblance measures were further investigated using linear mixed models.ResultsWe obtained 665 father-child and 798 mother-child resemblance measures. Mother-child resemblance was on average 0.57 and stronger than father-child resemblance (0.50, p < 0.0001), which was explained by a parent-respondent interaction: the diet of the child resembled more the diet of the parent who provided food consumption data for the child. In univariate models, father- and mother-reported number of family meals were positively associated with father-child and mother-child resemblances. Mother-reported number of family meals was positively associated with mother-child resemblance in a full model.ConclusionsThe diet of the child seems to resemble more the diet of the parent responsible for the reporting of food consumption. Studies should report who provided the food consumption data for the child and take this into account in analyses, since reporter-bias can influence the results.
