Paternal Death, Parental Divorce, and Timing of First Substance Use in an Ethnically Diverse Sample Journal of Child and Adolescent Substance Abuse 28,2 (2019): 83-91. Also: https://www.tandfonline.com/doi/full/10.1080/1067828X.2019.1580234 Cohort(s): Children of the NLSY79, NLSY79 Young Adult Publisher: Taylor & Francis Keyword(s): Alcohol Use; Childhood Adversity/Trauma; Cigarette Use (see Smoking); Drug Use; Parental Marital Status; Trauma/Death in family We examined timing of first alcohol, cigarette, and marijuana use as a function of paternal death or parental divorce during childhood. Data were drawn from a large ethnically diverse sample, including 4,880 Hispanic, Black, and White children and mothers. Survival analyses were conducted, predicting age at first substance use from parental loss, separately by substance class and child sex and racial/ethnic group. Results confirm risk of early use associated with parental divorce, especially among females, and highlight paternal death as a risk factor for some children. To inform prevention efforts, replication and extension of analyses to identify underlying mechanisms is necessary. |

Associations between Childhood and Adolescent BMI and Risky Sexual Behaviors in Adolescence Ph.D. Dissertation, School of Education, Indiana University, 2018 Cohort(s): Children of the NLSY79, NLSY79 Young Adult Publisher: ProQuest Dissertations & Theses (PQDT) Keyword(s): Adolescent Sexual Activity; Body Mass Index (BMI); Childhood; Modeling, Latent Class Analysis/Latent Transition Analysis; Sexual Behavior Permission to reprint the abstract has not been received from the publisher. This dissertation is the first-known study to document longitudinal associations between BMI and subsequent RSBs among adolescents, including examination of racial/ethnic differences. Using Economic Rationality Theory (ERT) and Life Course Theory as compatible guiding frameworks, latent growth curve modeling was conducted to examine relationships between BMI prospectively assessed from childhood through adolescence and engagement in subsequent RSBs, including early sex, multiple sexual partners, unprotected sex, and/or casual sex. Data were drawn from 8,095 Hispanic, Black, and White/other females and males from Children of the 1979 National Longitudinal Survey of Youth, a longitudinal study of biological children of women participating in a large-nationally representative sample of individuals aged 14-22 in 1979. |

Childhood Weight Status and Timing of First Substance Use in an Ethnically Diverse Sample Drug and Alcohol Dependence 164 (1 July 2016): 172-178. Also: http://www.sciencedirect.com/science/article/pii/S0376871616301119 Cohort(s): Children of the NLSY79, NLSY79 Young Adult Publisher: Elsevier Keyword(s): Alcohol Use; Body Mass Index (BMI); Child Growth; Child Health; Cigarette Use (see Smoking); Drug Use; Ethnic Differences; Gender Differences; Modeling, Hazard/Event History/Survival/Duration; Racial Differences; Substance Use; Weight Background: We examined associations between weight status during childhood and timing of first cigarette, alcohol, and marijuana use in an ethnically diverse sample. Methods: Data were drawn from child respondents of the 1979 National Longitudinal Survey of Youth, including 1,448 Hispanic, 2,126 non-Hispanic Black, and 3,304 non-Hispanic, non-Black (White) respondents aged 10 years and older as of last assessment. Cox proportional hazards regression was conducted predicting age at first use from weight status (obese, overweight, and underweight relative to healthy weight) assessed at ages 7/8, separately by substance class, sex, and race/ethnicity. Tests of interactions between weight status and respondent sex and race/ethnicity were also conducted. Results: Compared to healthy-weight females of the same race/ethnicity, overweight Hispanic females were at increased likelihood of alcohol and marijuana use and overweight White females were at increased likelihood of cigarette and marijuana use. Compared to healthy-weight males of the same race/ethnicity, obese White males were at decreased likelihood of cigarette and alcohol use and underweight Hispanic and Black males were at decreased likelihood of alcohol and marijuana use. Significant differences in associations by sex and race/ethnicity were observed in tests of interactions. Conclusions: Findings highlight childhood weight status as a predictor of timing of first substance use among Hispanic and Non-Hispanic Black and White female and male youth. Results suggest that collapsing across sex and race/ethnicity, a common practice in prior research, may obscure important within-group patterns of associations and thus may be of limited utility for informing preventive and early intervention efforts. |

Sexual Risk Behaviors during Adolescence: Associations with Childhood and Adolescent BMI Empirical Research 49 (2020): 1433-1446. Also: https://link.springer.com/article/10.1007/s10964-020-01192-3 Cohort(s): NLSY79 Young Adult Publisher: Springer Keyword(s): Adolescent Sexual Activity; Body Mass Index (BMI); Risk-Taking; Weight Permission to reprint the abstract has not been received from the publisher. Research examining associations between unhealthy weight and sexual risk behaviors derives primarily from cross-sectional studies conducted at varying ages during adolescence. The present study examined longitudinal associations between adolescent sexual risk behaviors and Body Mass Index (BMI), the latter measured prospectively from childhood through adolescence. Data were drawn from an 8095 individuals between the ages of 14 and 19 at last assessment, including 1768 Hispanic (52% female), 2659 non-Hispanic Black (Black; 50% female), and 3668 non-Hispanic, non-Black (predominantly White; 49% female). Childhood BMI predicted increased sexual risk-taking during adolescence for Black and White youth, and increases in BMI predicted increased sexual risk-taking for White females and Black males. The findings highlight differential patterns of association between BMI and sexual risk behaviors for Hispanic, Black, and White females and males with implications for prevention discussed. |

Associations between Childhood Weight Status and Timing of First Sex in an Ethnically Diverse Sample Childhood Obesity 14,8 (November/December 2018): 566-572. Also: https://digitalcommons.wustl.edu/cgi/viewcontent.cgi?article=8351&context=open_access_pubs Cohort(s): Children of the NLSY79, NLSY79 Young Adult Publisher: Mary Ann Liebert, Inc. Keyword(s): Ethnic Differences; Obesity; Racial Differences; Sexual Experiences/Virginity; Weight Permission to reprint the abstract has not been received from the publisher. Background: Most research linking weight status and timing of first sexual intercourse is cross-sectional in design, with few longitudinal analyses published to date. We examined associations between childhood weight status and subsequent onset of first sexual intercourse within a survival analytic framework, testing for differences among Hispanic, black, and white females and males. Methods: Data were drawn from 6379 child respondents of the 1979 National Longitudinal Survey of Youth aged 13 and older at last assessment. Cox proportional hazards regression models were estimated predicting age at first sexual intercourse from weight status during childhood without and with adjustment for correlated risk factors. Analyses were conducted separately by sex and race/ethnicity, with interactions among weight status, respondent sex, and race/ethnicity modeled in subsidiary analyses. Results: Overweight status predicted earlier sexual intercourse among Hispanic females, whereas obese status predicted delayed sexual intercourse among white males, both relative to peers of the same race/ethnicity with healthy weight. Underweight status predicted delayed sexual intercourse among Hispanic males relative to peers with healthy weight. Significant differences by sex and race/ethnicity were observed in tests of interactions. |
