Temporal trend of adolescent pregnancy in Brasil

Prevalence of sexual initiation and associated factors in school adolescents in Piauí, Brazil, 2015

OBJECTIVE

to analyze prevalence of sexual initiation and associated factors in adolescents in Piauí.

METHODS

this was a cross-sectional study, with secondary data from the 2015 National Adolescent School-based Health Survey. Hierarchical analysis was performed using robust Poisson regression.

RESULTS

a total of 3.872 adolescents were interviewed. Prevalence of sexual initiation was 24.2%; risk factors for sexual initiation were being male [prevalence ratio (PR) = 2.18; 95% confidence interval (95%CI) 1.90;2.47], being 15 years old or over (PR = 2.49; 95%CI 2.18;2.76), living with mother (PR = 0.68; 95%CI 0.54;0.82), working (PR = 1.82; 95%CI 1.55;2.10), attending a public school (PR = 1.39; 95%CI 1.09;1.75), practicing bullying (PR = 1.50; 95%CI 1.31;1.72), using alcohol (PR = 2.35; 95%CI 2.09;2.64), using cigarettes (PR = 1.46; 95%CI 1.22;1.70) and using illicit drugs (PR = 1.40; 95%CI 1.15;1.66).

CONCLUSION

prevalence of sexual initiation was high and associated with sociodemographic characteristics and vulnerable health behaviors, indicating the need for health promotion strategies.

Trends and factors related to adolescent pregnancies: an incidence trend and conditional inference trees analysis of northern Nicaragua demographic surveillance data

BACKGROUND

We aimed to identify the 2001-2013 incidence trend, and characteristics associated with adolescent pregnancies reported by 20-24-year-old women.

METHODS

A retrospective analysis of the Cuatro Santos Northern Nicaragua Health and Demographic Surveillance 2004-2014 data on women aged 15-19 and 20-24. To calculate adolescent birth and pregnancy rates, we used the first live birth at ages 10-14 and 15-19 years reported by women aged 15-19 and 20-24 years, respectively, along with estimates of annual incidence rates reported by women aged 20-24 years. We conducted conditional inference tree analyses using 52 variables to identify characteristics associated with adolescent pregnancies.

RESULTS

The number of first live births reported by women aged 20-24 years was 361 during the study period. Adolescent pregnancies and live births decreased from 2004 to 2009 and thereafter increased up to 2014. The adolescent pregnancy incidence (persons-years) trend dropped from 2001 (75.1 per 1000) to 2007 (27.2 per 1000), followed by a steep upward trend from 2007 to 2008 (19.1 per 1000) that increased in 2013 (26.5 per 1000). Associated factors with adolescent pregnancy were living in low-education households, where most adults in the household were working, and high proportion of adolescent pregnancies in the local community. Wealth was not linked to teenage pregnancies.

CONCLUSIONS

Interventions to prevent adolescent pregnancy are imperative and must bear into account the context that influences the culture of early motherhood and lead to socioeconomic and health gains in resource-poor settings.

Experiences of interaction between teenage mothers and visiting nurses: a phenomenological study

OBJECTIVE

To understand the experiences of interaction between teenage mothers and visiting nurses in the Young Mothers Caregivers Program.

METHOD

Qualitative research using the theoretical-methodological framework of Social Phenomenology, with phenomenological interviews with visiting nurses and teenage mothers.

RESULTS

Three visiting nurses and nine teenage mothers participated. The understanding of the experiences led to the elaboration of three categories of contexts of meanings related to the past and present: "Experiences of participation in the PJMC"; "The interaction experienced by visiting nurses and teenage mothers"; "Parenting and maternal role".

CONCLUSION

The interaction between visiting nurses and teenage mothers in the program was characterized as positive, as it provided the mother with greater security in her maternal and parental role. The attitudes of nurses and adolescent mothers were fundamental for establishing a positive interaction.
