The Brant County CHSR contains chapters focusing on demographics, reproductive health, lifestyles and determinants of health, as well as the causes of disease and death. Information is analyzed by age and sex, and is compared to all of Ontario. Please refer to the full report for details on any of the topics and chapters discussed in this Overview. THE COMMUNITY??

Teen birth rates rose in Brant County between 1997 and In 1999, the teen birth rate (livebirths plus stillbirths) in Brant County (33/1,000) was almost twice the rate found in the neighbouring Health Unit areas and in Ontario as a whole (18/1,000) Pregnancy* Rates per 1,000 women by Age Age Residence Brant County Ontario *Pregnancies include live births, still births, therapeutic abortions, miscarriages, and ectopic pregnancies.?? Between 1993 and 1997, births among single mothers in Brant County increased from 23% to 28%. By comparison, this proportion stayed at approximately 18% throughout Ontario.?? Low birthweight (LBW) is associated with infant mortality and the potential for future adverse health outcomes. Approximately 6% of all births in Brant County had a LBW in 1997 (4.3% of singleton births and more than half of all multiple births), similar to Ontario.?? Approximately 8% of Brant County babies were born prematurely half with a low birth weight. Premature birth has been found to put infants at risk of death or potential future health problems.??

Between 1993 and 1997 the perinatal mortality rate in Brant County was similar to the provincial rate, ranging from a high of 12 to a low of 7 per 1,000 births. In 1997 the rate was 10 per 1,000. Perinatal deaths include stillbirths and deaths prior to 7 days of age.?? A key group of congenital defects relevant to public health are neural tube defects, because they are preventable with adequate intake of folic acid (folate). The incidence of neural tube defects was less than five per year between 1993 and 1997 in Brant County.
