This guide is designed primarily for nutritionists and other health providers who work with pregnant adolescents, aged 17 or younger. The guide lists psychosocial, educational, and health implications of early pregnancy, and discusses the nutritional risks and requirements of pregnant teenagers. The guide then identifies counseling and educational strategies that can be geared to the pregnant teens' specific nutritional needs and lifestyles; topics presented include establishing rapport, setting nutritional goals, dispelling myths about food and pregnancy, identifying nutritious snacks, and counseling teens who follow unusual or fad diets. The remainder of the guide contains four sample lesson plans that can be used flexibly in group or individual sessions by either health professionals or paraprofessionals. Topics are: (1) How a Baby Grows; (2) Nutrition for the Mother-To-Be; (3) Food Choices; and (4) Drugs, Tobacco, and Alcohol During Pregnancy. The format for the lessons includes statement of target group (stage of pregnancy), objectives, materials needed, learning activities, and suggested evaluation activities. Optional activities are presented for some lessons. An appendix deals with the effects of specific drugs, alcohol, tobacco, and caffeine on the fetus. (WAS)
