Reproductive health problems in rural South African young women: risk behaviour and risk factors

2018

Background South African young women continue to be vulnerable, with high prevalence of teenage pregnancy, HIV, sexually transmitted infections (STIs) and female genital schistosomiasis (FGS). This study seeks to examine the underlying factors that may be associated with these four adverse reproductive health outcomes. Methods In a cross-sectional study of 1413 sexually active of young women, we explored these four adverse reproductive health outcomes by considering socio-demographic factors, socio-economic factors, sexual risk behaviour, substance abuse and knowledge about reproductive health by using a questionnaire. Consenting participants were asked about previous pregnancies and were t…

Influential Periods in Longitudinal Clinical Cardiovascular Health Scores

2021

Abstract The prevalence of ideal cardiovascular health (CVH) among adults in the United States is low and decreases with age. Our objective was to identify specific age windows when the loss of CVH accelerates, to ascertain preventive opportunities for intervention. Data were pooled from 5 longitudinal cohorts (Project Heartbeat!, Cardiovascular Risk in Young Finns Study, The Bogalusa Heart Study, Coronary Artery Risk Development in Young Adults, Special Turku Coronary Risk Factor Intervention Project) from the United States and Finland from 1973 to 2012. Individuals with clinical CVH factors (i.e., body mass index, blood pressure, cholesterol, blood glucose) measured from ages 8 to 55 year…

The socialization of coping strategies in adolescence: the modeling role of parents

2020

Background and Objectives: The main aim of this study is to test the intergenerational transmission of the relations between coping strategies to well-being from parents to adolescents through the modeling of the coping strategies of the parents to those of the child. Methods: 154 cohabitating families composed by father, mother, and adolescent in age range between 14 and 18 (M = 16.40; SD = 1.53) took part to the research. To test the proposed model, SEM with observed variables and the integration of the APIM approach and the Bootstrapping approach was used. Results: Findings showed in both parents and adolescents significant positively relations between coping task strategy and well-being…

The presence of a woman increases testosterone in aggressive dominant men

2008

In line with the challenge hypothesis, this study investigated the effects of the presence of a woman on the testosterone (T) levels of young men. An informal contact with a woman of approximately 5 min resulted in an increase in salivary T among men. These effects occurred particularly in men with an aggressive dominant personality. In addition, higher salivary T levels were related to a more aggressively dominant personality, being sexual inactive for a month or more, and not being involved in a committed, romantic relationship. The most important findings of this study are that the short presence of a woman induces specific hormonal reactions in men, and that these effects are stronger f…

Genetic and Environmental Effects on the Individual Variation and Continuity of Participation in Diverse Physical Activities

2021

INTRODUCTION Participation in diverse physical activities has beneficial health effects. However, little is known on how genetic and environmental factors affect this trait. Thus, we examined to what extent these factors explain participation in diverse leisure-time physical activities from late adolescence to adulthood using a twin study design. METHODS The participants were Finnish twins who reported their participation in diverse leisure-time physical activities at ages 17 (n = 5429) and 34 yr (n = 4246). The number of physical activities engaged in was analyzed using applications of structural linear modeling for twin data. RESULTS On average, the total number of physical activities eng…

Hereditary Progressive Mucinous Histiocytosis in Women

1988

We describe three female patients in a family of two generations, who suffered from generalized and maximally pea-sized histiocytic tumors beginning in early adolescence. The disease ran a uniform and slowly progressive course and was confined to the skin. There were no signs of spontaneous tumor regression. Histologic, immunohistochemical, and ultrastructural examination revealed the histiocytic nature of the tumors. An outstanding finding was a marked production of mucinous material, predominantly in long-standing tumors. This nonlangerhansian syndrome differs from other benign normolipemic histiocytic diseases with generalized histiocytic tumors by inheritance, which is most likely autos…

The relapse rate of multiple sclerosis changes during pregnancy: a cohort study

2004

Objective – To evaluate the influence of pregnancy and puerperium on the relapse rate of multiple sclerosis (MS). Methods – We determined retrospectively the yearly mean relapse rate (MRR) during pregnancies occurring in the course of relapsing–remitting MS. We compared the MRR of pregnancy-time with that of non-pregnancy time by paired t-test. Relative risk (RR) of relapses during the pregnancy-time was also compared with that of non-pregnancy time by χ2 analysis and 95% confidence intervals. Results – From a population of 351 women affected by clinically definite MS, only 70 reported pregnancies during their relapsing–remitting phase of MS for a total of 98 pregnancies. Both MRR (P = 0.00…

Mediadores psicológicos y motivación deportiva en judocas españoles.

2006

El presente trabajo analizó las diferencias de la motivación en situación precompetitiva de judocas en función de los mediadores psicológicos (percepciones de competencia, apoyo a la autonomía y relaciones sociales), tal y como postula el Modelo Jerárquico de la Motivación Intrínseca, Extrínseca y Amotivación (Vallerand, 1997, 2001; Vallerand y Losier, 1999). Se empleó una muestra de 181 judocas de edades comprendidas entre los 14 y 16 años. Utilizamos una metodología selectiva, con diseño prospectivo simple. Los datos se analizaron mediante un MANOVA, tomando como variables independientes los mediadores psicológicos y el sexo de los deportistas y como variables dependientes cada una de las…

Early motherhood: voices from female adolescents in the Hohoe Municipality, Ghana—a qualitative study utilizing Schlossberg’s Transition Theory

2020

ABSTRACT Purpose: Using Schlossberg’s Transition Theory, this study explored the lived experiences of pregnant adolescents and adolescent mothers coping strategies during their transition to motherhood. Methods: Based on a phenomenological perspective, this qualitative study used in-depth interviews (IDIs) and focus group discussions (FGDs) to answer the research aim. The process of data gathering included 8 FGDs and 12 IDIs held with adolescent mothers and pregnant adolescents. Audio recordings were transcribed and imported into MAXQDA 2018 for analysis. Results: Applying the interpretative phenomenologial analysis (IPA), four key themes emerged. This included: news of pregnancy; adolescen…
