Am J Prev Med 2000;19:47–52 The purpose of the study was to determine the relationship between a woman's social integration and her likelihood of recalling having had a Pap smear. The population consisted of 2,383 women over the age of 40 drawn from a consortium of public health organization in California, Texas, New York, and Florida. A telephone survey was conducted among Mexican, Central American, Puerto Rican, and Cuban women using measures of language acculturation and social integration (church attendance, number of close relatives/friends). Social integration was positively linked to the likelihood of having had a recent Pap smear more than to mammography. The link was not significant for Puerto Rican women or for mammography. The likelihood of a recent Pap smear ranged from 45% among Mexican-American women with low levels of social integration to 75% among Cuban-American women with high levels of social integration. Comment: Cervical cancer rates are high among Hispanic women. Many outreach efforts involve recruitment to screening through social networks. This study suggests that improved outreach may depend on strategies to reach women who are not tightly integrated into their communities. It also identifies differences among Hispanic populations, suggesting that it may not be possible to generalize a single approach to improving cancer screening to all Hispanic communities. (LSM)
