Maternal characteristics and prenatal factors were compared for 1,279 live born infants with gastroschisis and 3,069,678 without. Data were obtained using the California database containing linked hospital discharge, birth certificate and death records from 1 year prior to the birth to 1 year after the birth. Backwards\u2010stepwise logistic regression models were used with maternal factors where initial inclusion was determined by a threshold of <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.10 on initial crude analyses. Due to the strong association of gastroschisis with young maternal age, models were stratified by age groups and odds ratios were calculated. These final models identified maternal infection as the only risk factor common to all age groups and a protective effect of obesity and gestational hypertension. In addition, age specific risk factors were identified. Although gestation at the time of infection was not available, a sexually transmitted disease complicating pregnancy was associated with increased risk in the less than 20 years of age grouping whereas viral infection was associated with increased risk only in the 20\u201324 and more than 24 years of age groupings. Urinary tract infection remained in the final logistic model for women less than 20 years. Short interpregnancy interval was not found to be a risk factor for any age group. Our findings support the need to explore maternal infection by type and gestational timing. \u00a9 2015 Wiley Periodicals,
