  • Cohort
  • The goal of this study was to identify the effect of the change in body mass index (BMI) from childhood to adulthood on body image satisfaction at 23 years of age in members of the 1982 Pelotas Birth Cohort in Pelotas, RS, Brazil. (biomedcentral.com)
  • The Add Health cohort has been followed into young adulthood with four in-home interviews, the most recent in 2008, when the sample was aged 24-32. (umich.edu)
  • The fourth wave of interviews expanded biological linkages in health trajectories as the Add Health cohort ages through adulthood. (umich.edu)
  • Differences
  • In addition, gender and grade-level differences in problem behavior engagement were addressed examining latent mean differences. (ed.gov)
  • Overall, analyses revealed that both gender and grade-level differences could be explained by the common cause problem behavior syndrome (PBS), offering further support for Jessor's theory. (ed.gov)
  • and (8) differences in cheating behaviors according to the length of duration of Christian commitment. (unt.edu)
  • The study of the process of child-support receipt shows the extent of pre-existing differences between the children receiving child support payments and children who are eligible but not receiving child support payments. (nlsinfo.org)

  • While religion is the main reason for differences in abortion attitudes, religion is a relatively minor reason for differences in abortion behavior. (medicalnewstoday.com)
  • antisocial behavior
  • The study focused on whether genes are likely to cause a person to become a life-course persistent offender, which is characterized by antisocial behavior during childhood that can later progress to violent or serious criminal acts later in life. (redorbit.com)
  • In addition, we find that youth who reside with a single biological parent who cohabits with a nonbiological partner exhibit an unusually high rate of antisocial behavior, especially if the custodial parent is the biological father. (nlsinfo.org)
  • attitudes
  • This study extends prior research by longitudinally testing these associations across racial/ethnic groups and investigating whether culturally relevant variations within racial/ethnic minority groups, such as skin tone (i.e., lightness/darkness of skin color), are linked to attitudes toward marriage and cohabitation and sex. (pubmedcentralcanada.ca)
  • Drawing on family and public health literatures and theories, as well as burgeoning skin tone literature, it was hypothesized that more positive attitudes toward marriage and negative attitudes toward cohabitation would be associated with less risky sex, and that links differed for lighter and darker skin individuals. (pubmedcentralcanada.ca)
  • Studies have also begun to use a family life cycle perspective to investigate how behaviors, including sexual behavior, may be linked to marriage and cohabitation attitudes. (pubmedcentralcanada.ca)
  • Understanding the impact of marriage and cohabitation attitudes on decisions about sex is particularly important because this work may help scholars to better understand how such beliefs shape and alter individual and relational behaviors during a critical period for individual and relational development ( Arnett and Tanner 2006 ). (pubmedcentralcanada.ca)
  • Peers have a powerful effect on adolescents' beliefs, attitudes, and behaviors. (springer.com)
  • Thus, it is unclear whether social network influence generalizes to all aspects of romantic and sexual relationship development or applies only to specific behaviors and attitudes. (springer.com)
  • A new study in the journal Social Science Quarterly reveals that religious women are less likely to obtain abortions than secular women, not because religious women have stronger pro-life attitudes, but because religious women are more likely to lead a sexually conservative lifestyle. (medicalnewstoday.com)
  • Religious influences on attitudes are much more powerful than religious influences on behavior," the authors note. (medicalnewstoday.com)
  • predictors
  • An understanding of the determinants or predictors of the timing of sexual debut is important for effective intervention, but very few studies to date have addressed this issue in the Nigerian context. (biomedcentral.com)
  • deviant behavior
  • Abstainers represent a smaller number of people who donĀ“t engage in any deviant behavior. (redorbit.com)
  • The link between genes and crime is a divisive issue in the criminology discipline, which has primarily focused on environmental and social factors that cause or influence deviant behavior. (redorbit.com)
  • Protective functions of family relationships and school factors on the deviant behavior of adolescent boys and girls. (springer.com)
  • associated with violent behavior
  • Poisson regression was used to analyze contributors to violence in just wave I, and then again across time in wave II using explanatory and control variables from wave I. Results indicate that hopelessness is positively associated with violent behavior. (byu.edu)
  • overweight
  • The Brazilian nationwide survey entitled The Surveillance of Risk and Protective Factors for Chronic Diseases through Telephone Survey study (VIGITEL) [ 3 ] from the Health Ministry reveal that more than half of the Brazilian population is overweight, interviewed 45,000 adults, and 51% of the interviewees mentioned excess weight. (biomedcentral.com)
  • Body dissatisfaction is central to the health and well-being of children and adolescents who are overweight. (biomedcentral.com)
  • developmental
  • The framework for the research was based on the developmental taxonomy of anti-social behavior, a theory derived by Dr. Terri Moffitt, who identified three groups, or pathways, found in the population: life-course persistent offenders, adolescent-limited offenders and abstainers. (redorbit.com)
  • Emerging developmental perspectives suggest that adverse rearing environments promote neurocognitive adaptations that heighten impulsivity and increase vulnerability to risky behavior. (cambridge.org)
  • Although studies document links between harsh rearing environments and impulsive behavior on substance use, the developmental hypothesis that impulsivity acts as mechanism linking adverse rearing environments to downstream substance use remains to be investigated. (cambridge.org)
  • Third, in addition to analyzing the social demographic and developmental precursors of family formation behaviors, the study also explored the implications of family formation patterns for psychosocial well-being in emerging adulthood, including psychological and behavioral adjustment, psychosocial maturity, and intimate relationship quality. (umich.edu)
  • violent
  • We find little evidence that adolescent depression predicts the likelihood of engaging in violent crime or the selling of illicit drugs. (nber.org)
  • The major focus of this study was to test the theory driven conceptual model derived from the literature regarding risk, protective and desistance factors in relation to violent behavior of female adolescents. (springer.com)
  • The conceptual model developed was based on life course perspective as it relates to violent behavior in adolescents. (springer.com)
  • Furthermore, while hopelessness and most of the other explanatory variables predicted violent behavior in wave I, almost all the variables became non-significant or negative except hopelessness and a measure of community when predicting violence in wave II. (byu.edu)
  • suicidal thoughts
  • The majority of well-conducted studies found that higher levels of religious involvement are positively associated with indicators of psychological well-being (life satisfaction, happiness, positive affect, and higher morale) and with less depression, suicidal thoughts and behavior, drug/alcohol use/abuse. (scielo.br)
  • Analyses
  • 6 Retrospective analyses using the 1982 National Survey of Family Growth (NSFG) suggest that this increase began in the late 1960s. (guttmacher.org)

  • males
  • Although adolescent sexual minority males (ASMM) are at increased risk for human immunodeficiency virus (HIV) in the United States (US), studies that estimate sexual risk behaviors that contribute to HIV risk in ASMM are limited. (springer.com)
  • We searched four databases for key terms related to ASMM, defined as males aged 14 through 19 who identified as gay or bisexual, reported sex with a male in their lifetime, and/or were considered sexual minority by the study. (springer.com)
  • Sixty-two percent of adolescent males self-identifying as gay or bisexual ever had sex with a male, and 67% of participants from ASMM studies recently had sex. (springer.com)
  • In the United States (US), the risk of HIV infection in adolescent sexual minority males (ASMM) is high, as evidenced by the few published estimates in this population. (springer.com)

  • Researchers using NSAM found that teen males were significantly more likely to report participation in many health risk behaviors using the computer rather than the paper self-administered questionnaires. (hhs.gov)
  • genes
  • Here we investigate two specific genes that may contribute to variation in voting behavior. (blogspot.com)
  • These are the first results ever to link specific genes to political behavior. (blogspot.com)
  • Interestingly, some of the genes with indirect or associative effects in hens involve the serotonin pathway, which has also been shown to influence social behavior in humans ( 15 , 16 ). (pnas.org)

  • In particular, this study examined cohabitation, childbearing (non-marital and marital), and marriage up to the age of 25. (umich.edu)
  • sexually
  • 1 Moreover, adolescents who have initiated sexual intercourse have some of the highest age-specific rates of sexually transmitted diseases (STDs), 2 which along with unintended pregnancy impose enormous costs in human pain and suffering, in social and economic opportunity, and in social welfare and health care.
