background: Changing birth rates can have significant population health impacts. This overview characterizes birth rate trends from 1990 to 2012 in Los Angeles County (LAC) and assesses the likely health impacts of these changing rates.

methods: Total Fertility Rate (TFR) and age-specific birth rate trends were calculated using numerators based on a subset of 1.65 million births from women of childbearing ages (10-54 years) recorded in the California Birth Statistical Master File (BSMF). Adverse birth and maternal outcomes were also derived.

results: The TFR for LAC dropped precipitously from 1990 to 2010, from 2.7 to 1.8 births, below that of both California and the US (1.9 each). During the same period, age-specific birth rates decreased for all maternal age groups between the ages of 15-34, but increased for women aged 35-49 years.  The percentage of older women (age 40-44 years) delivering prematurely was 14% compared with 10% for women age 30-34 years. Among older women, 11% delivered low weight babies compared with 7% of women 30-34 years. The percentages of older women developing gestational diabetes and preeclampsia were 74% and 64% higher than for women age 30-34 years..

conclusions: Since 1990, LAC has experienced dramatic changes in birth trends. While there has been a steep drop in birth rates among younger women, births to older women have been gradually increasing, along with their concomitant health risks. Policymakers’ recognition of these trends and their possible health impacts are stressed.
