Background Emerging data suggest that problem/pathological gambling may be highly prevalent among Asian-Pacific Islanders (APIs) and that can be a major concern to their communities. Methods This study surveyed problem/pathological gambling knowledge, attitudes, and perceived community impact of problem gambling among self-identified male and female APIs and non-APIs attending one of two API community events in Los Angeles County. Results Unexpectedly, our results indicated no effect for ethnicity with regards to ratings of problem/pathological gambling knowledge, community impact, or consequences. However, a gender effect with women reporting less problem/pathological-gambling-related knowledge than men, regardless of ethnicity was found. Over 40% of all respondents reported that problem/pathological gambling impacted their communities ‘a lot’, and the ratings for the impact of problem/pathological gambling was equal to ratings for other significant public health issues like diabetes, depression, drug abuse, and alcohol abuse. Discussion Based on these results, it is recommended that evidence-based legislation support the development of culturally-relevant prevention and intervention programs for problem/pathological gambling in Los Angeles County.
