A growing body of evidence has implicated the potential of paternal exposures to affect birth outcomes in future offspring. In particular, certain occupational and chemical exposures are linked to increased risk of birth defects and other morbidities in their children. In a partnership between Operation Smile, University of Southern California and Children’s Hospital Los Angeles, an investigation was conducted with fathers from global, multi-ethnic groups through an interviewer-based questionnaire. A total of 377 fathers of cleft case children and non-cleft controls were recruited in a hospital-based sampling from the Democratic Republic of Congo (34 cases, 6 controls), Honduras (50 cases, 8 controls), Morocco (26 cases, 9 controls), Philippines (70 cases, 66 controls) and Vietnam (96 cases, 12 controls). Statistical analyses are underway, using logistic regression, Chi-square analysis and t-tests to compare paternal case and control reports within and between each country. Odds ratios and risk determination will be calculated in the analysis. Variables being analyzed include self-reported demographic characteristics, occupational history, chemical exposures, health conditions and family history. Particular emphasis is placed on the periconception period, defined as 12-18 months before the birth of the child. Results from our study will contribute information from an understudied, diverse and resource-poor paternal population to encourage awareness and potential interventions in periconception.
