The number of people who entered the health fair was 172, with 73 fitting the inclusion criteria (Chinese women aged 18-55 years). The total number of subjects who answered the questionnaire and were examined was 69; therefore, the participation rate was 95%. The average age of the participants was 42 years. A total of 67 of the 69 were born outside the United States, with an average age of immigration of 32 years. The 2 American-born Chinese women had their questionnaires read to them owing to their lack of Chinese reading skills, and both expressed full understanding. Most of the women were from China (70%) and Taiwan (17%), while the remaining were from Vietnam, Singapore, Cambodia, and Malaysia. The sample contained 44 and 31 cases of lentigines and PIH, respectively, but only 11 cases of melasma (Figure 2). The question regarding self-report of lentigines had a mean (SD) sensitivity of 93.2% (3.8%) and specificity of 96.0% (3.9%). For PIH, sensitivity was 100.0%, and specificity was 92.1% (4.4%), whereas the question on melasma had a sensitivity of 81.8% (11.6%) and a specificity of 93.1% (3.3%).
