Cardiovascular health decline in adolescent girls in the NGHS cohort, 1987-1997.

ABSTRACT: Adolescence is a critical time for the preservation or loss of cardiovascular health. We aimed to describe trajectories of cardiovascular health in adolescent girls and identify early adolescent factors associated with cardiovascular health in young adulthood. We used data from the National Growth and Health Study, a longitudinal cohort of 2,379 girls followed annually from ages 9-19 years. We classified participants as having ideal, intermediate, or poor levels of the seven cardiovascular health metrics at four developmental stages: early (ages 9-11), middle (ages 12-14), and late (ages 15-17) adolescence, and early young adulthood (ages ? 18). We calculated total cardiovascular health scores (range 0-14) at each stage and empirically identified patterns of cardiovascular health trajectories. We examined associations between trajectory group membership and various demographic, behavioral, and physiological factors. Mean cardiovascular health scores declined with age from 10.8 to 9.4 in white girls and 10.3 to 8.9 in black girls; 17% of white girls and 23% of black girls had low cardiovascular health (score < 8) by early young adulthood. We identified five cardiovascular health trajectories: high-stable (14% of participants), high-to-moderate (48%), high-to-low (20%), moderate-stable (10%), and moderate-to-low (8%). Exceeding 14 h per week of television in early adolescence and teen pregnancy were associated with higher odds of being in several less healthy trajectory groups. In conclusion, cardiovascular health declines during adolescence and black-white disparities begin before early adolescence. Key targets for improving cardiovascular health in adolescent girls may include reductions in sedentary behavior and prevention of teen pregnancy.

Project description:Introduction and backgroundEarly marriage and maternity represent a violation of human rights and a barrier to achieving gender equality in education. Studies conducted across various regions and countries, including Mozambique, have highlighted the negative consequences of early marriage and maternity, particularly on adolescent girls' physical, educational and mental health. Adolescent girls who marry before the age of 18 are more prone to a broad spectrum of mood, anxiety, and other psychiatric disorders. In the districts of Maganja da Costa and Morrumbala in Zambézia Province, Mozambique, high rates of early marriage persist despite government policies and interventions.Purpose statementThis study aims to understand early marriage's socio-cultural, economic, and psychological drivers and impacts on adolescent girls' lives, focusing on education, mental health, and well-being.Design and methodsThis paper used a qualitative research design. We employed a life-story approach and used purposeful sampling to identify participants. Semi-structured interviews were conducted with 25 participants and the data were analysed using Tesch's thematic analysis approach.ResultsElements contributing to early marriage and pregnancy are intricately linked with socio-cultural elements. These include the induction into specific societal roles, the affirmation of childbearing, the perceived importance of dowry, the impact of rite-of-passage ceremonies, and the cultural significance associated with a girl's initial menstruation. School dropout often originates from geographical and transportation challenges, nudging adolescent girls towards early marriage. In some instances, termination of pregnancy was viewed as a solution, while engaging in sexual activities was seen as a means to inject purpose into their lives or as a response to poverty. Positive changes and emotions were evident, yet regrettably, the ramifications of early pregnancy and marriage were primarily detrimental. These influenced the adolescent girls' interpersonal connections, educational and career opportunities, emotional well-being, and access to support networks.ConclusionsThe modern perspective, which advocates for equal educational rights for boys and girls and posits that marriage should occur after the age of 18, contradicts the socio-cultural perspective of adulthood.ContributionThis study adds to the ongoing efforts to prevent and combat early marriage and maternity in Africa.

Project description:BackgroundEarly adolescence is a critical window for intervention when it is possible to lay a foundation for a safe transition to adulthood, before negative outcomes occur. The Adolescent Girls Initiative-Kenya randomized trial tested the effects of combinations of interventions for young adolescent girls in two sites - the Kibera informal settlement in Nairobi and rural Wajir County in the Northeastern region.MethodsThe interventions included community dialogues on the role and value of girls (violence prevention), a conditional cash transfer (education), weekly group meetings for girls with health and life skills training (health), and training and incentives for financial literacy and savings activities (wealth creation). Participants were randomized to one of four study arms: 1) violence prevention only, 2) violence prevention and education, 3) violence prevention, education and health or 4) violence prevention, education, health and wealth creation. An intent-to-treat (ITT) analysis was conducted using longitudinal data to estimate the impact of each combination of interventions and various sensitivity analyses conducted addressing potential attrition bias and multiple hypothesis testing concerns.ResultsIn Kibera, the education conditional cash transfer had small effects on grade attainment but larger impacts on completion of primary school and the transition to secondary school in the most comprehensive arm; the health intervention improved sexual and reproductive health knowledge and condom self-efficacy; and the wealth intervention improved financial literacy and savings behavior. In Wajir, the education conditional cash transfer increased school enrollment and grade attainment, and the wealth intervention improved savings behavior.ConclusionsThe results indicate that when trying to improve a range of outcomes related to adolescent wellbeing for young girls, a multisectoral intervention with components addressing household economic constraints is a promising approach.Trial registrationTrial Registry: ISRCTN, ISRCTN77455458 .

Project description:BackgroundInduced abortion among adolescent girls is a global public health issue and a serious challenge in China, but still remains under-examined. We aimed to examine the overall trend and characteristics of induced abortions among Chinese adolescent girls and to investigate the factors associated with induced abortion.Study designBased on the 2017 China Fertility Survey, this study examined the trend and characteristics of induced abortions among adolescent girls with statistical analysis and multiple indicators of descriptive statistics from period and cohort perspectives, including induced abortion proportion and rate, age-specific cumulative proportion, and age-specific cumulative number of induced abortions in adolescent girls.ResultsBetween 1996 and 2016, the proportion and rate of adolescent induced abortions first increased and then decreased, and the mean age at the time of induced abortions among adolescent girls declined. The cumulative proportion of women who had experienced induced abortion at the age of 15-19 in a cohort is less than 2.5% but shows an upward trend. Over 70% of all adolescent induced abortions are premarital. The proportion of women with unintended pregnancy experiences increased and is higher among rural, less educated, and ethnic minority women. Similarly, the prevalence of induced abortion is higher among adolescent girls who live in rural areas, are less educated, and come from ethnic minorities. The cumulative number of induced abortions and premarital abortions increased with later cohorts.ConclusionsThis study shows an upward trend in adolescent-induced abortion and a decline in the age at the time of the induced abortion. Women in later birth cohort have a higher proportion of having experienced adolescent induced abortion. Adolescent girls who live in rural areas, who are less educated, or who are from ethnic minorities, are more likely to undergo induced abortions at the age of 15-19. More appropriate educational efforts and interventions are urgently needed to reduce the incidence of adolescent induced abortions.

Project description:ObjectivesTo systematically review interventions that include an element of menstrual education delivered to young adolescent girls.DesignThis was a systematic review and meta-analysis. Selected articles were quality assessed using the Mixed Methods Appraisal Tool quality appraisal checklist. A meta-analysis was conducted on a subset of articles, and the effect size of the intervention was calculated using Cohen's d. A logic model was constructed to frame the effect of menstrual education interventions on menstrual health.SettingPapers reporting on interventions in high-income and low-income and middle-income countries were sought.Information sourcesSeven electronic databases were searched for English-language entries that were published between January 2014 and May 2020.ParticipantsThe interventions were aimed at younger adolescent girls aged 10-14 years old.InterventionsThe interventions were designed to improve the menstrual health of the recipients, by addressing one or more elements of menstrual knowledge, attitude or practices (KAP).Eligibility criteriaInterventions that had not been evaluated were excluded.Primary and secondary outcomesThe most common type of output was a difference in knowledge or skill score ascertained from a pre and post test. Some studies measured additional outcomes, such as attitude or confidence.ResultsTwenty-four eligible studies were identified. The number of participants varied from 1 to 2564. All studies reported improvements in menstrual KAP. The meta-analysis indicates that larger effect sizes were attained by those that encouraged discussion than those that distributed pamphlets.ConclusionsEducation interventions are effective in increasing the menstrual knowledge of young adolescent girls and skills training improves competency to manage menstruation more hygienically and comfortably. Interactive interventions are more motivating than didactic or written. Sharing concerns gives girls confidence and helps them to gain agency on the path to menstrual health.Trial registration numberFor this review, a protocol was not prepared or registered.
