Having an older sister who was a teen mom significantly increases the risk of teenage childbearing in the younger sister and daughters of teenage mothers were significantly more likely to become teenage mothers themselves [8, 9].Girls having both a mother and older sister who had teenage births experienced the highest odds of teenage pregnancy, with one study reporting an odds ratio of 5.1 (compared with those who had no history of family teenage pregnancy) .Understanding the risk factors for teenage pregnancy is a prerequisite for reducing rates of teenage motherhood.Tags: Lab Safety AssignmentCollege Art AssignmentsResearch Paper Topics ListEssay On A Place Of Interest I VisitedNo Essay ScholorshipsEssays On Behaviour In The ClassroomBest Material Physics Coursework
By controlling for a variety of social and biological factors (such as neighborhood socioeconomic status, marital status of mother, residential mobility, family structure changes, and mental health), and the use of a strong statistical design—propensity score matching with a large population-based dataset—this study aims to determine whether teenage pregnancy is more strongly predicted by having an older sister who had a teenage pregnancy or by having a mother who bore her first child before age 20.
The setting of this study, Manitoba, is generally representative of Canada as a whole, ranking in the middle for several health and education indicators [12, 13].
Sisters were defined as having the same biological mother.
The cohort consists of women who were born in Manitoba between April 1, 1979 and March 31, 1994, stayed in the province until at least their 20 birthday, had at least one older sister, and had no missing values on key variables.
Health variables are measured continuously from physician claims and hospital abstracts (as long as an individual remains in Manitoba) .
A research registry identifies every provincial resident, with information on births, arrival and departure dates, and deaths created from the provincial health registry and coordinated with Vital Statistics files.
At the time of the 2011 Census, approximately 1.2 million people resided in Manitoba, with more than half (783,247) living in the two urban areas, Winnipeg and Brandon .
Teenage pregnancy rates in Manitoba exceed the national; in 2010 teenage pregnancy rates in Canada were 28., in Manitoba the rate was 48. .
After this adjustment, the odds of teenage pregnancy for teens with at least one older sister who had a teenage pregnancy were reduced to 2.48 (99 % CI 2.01–3.06) and the odds of pregnancy for teen daughters of teenage mothers were reduced to 1.39 (99 % CI 1.15–1.68).
Although both were significant, the relationship between an older sister’s teenage pregnancy and a younger sister’s teenage pregnancy is much stronger than that between a mother’s teenage childbearing and a younger daughter’s teenage pregnancy.
