ABCNews' "Nightline" on Wednesday profiled Luwana Marts, a nurse in Louisiana who makes in-home visits to low-income women from pregnancy until their infants are age two. Marts works with the Nurse-Family Partnership, a government-supported program that seeks to break the cycles of poverty, domestic abuse and addiction as well as reduce the number of teen pregnancies in the state, where the teen pregnancy rate is 30% higher than the national average, according to ABCNews. NFP provides a "total intervention" for women on subjects such as nutrition, exercise, budgeting and career development, according to ABCNews. In addition, there is a focus on relationship counseling, sexual behavior and birth control because a goal of the program is to lengthen the amount of time between pregnancies, ABCNews reports. The segment includes comments from Marts and some of her clients ("Nightline," ABCNews, 3/8).
