Diabetes mellitus in adolescents: a comprehensive approach to outpatient care.

A comprehensive approach to care of adolescents with diabetes mellitus requires knowledge of the unique characteristics of juvenile diabetes during this development period, appropriate medical goals, and awareness of the numerous psychologic and social problems encountered. Involvement of other health professionals is frequently needed. Successful adjustment of the adolescent to having diabetes includes absence of "maladaptive" coping mechanisms, realistic future goals, and acceptance of responsibility for self-care.

The relationship of serum alkaline phosphatase concentrations to sex maturity ratings in adolescents.

The relationship of serum alkaline phosphatase concentrations to sex maturity ratings, age sex, and race was studied in healthy prepubertal and adolescent patients. Previous data concerning SAP concentrations in adolescents have been age related and do not give primary consideration to biologic growth during adolescence. The highest mean concentrations for girls occurred at SMR 2 and for boys at SMR 3, coinciding in each instance with peak height velocity and thus correlating with presumed maximum osteoblastic activity during growth. With increasing SMR or age, the SAP levels in both sexes decreased markedly. Black boys had higher SAP concnetrations than white boys at SMRs 2, 3 and 4, whereas black girls had higher values than white girls only at SMR 4. This study demonstrates the value of correlating the enzyme activity with sex maturity ratings rather than with chronologic age.

Iron intake and transferrin saturation in adolescents.

The relationship of maturity, age, race, sex and income level to dietary intake and body stores of iron, as indicated by percent of transferrin saturation, was studied in healthy adolescents. Maturity rating, sex, and race were significant. Level of family income was not a significant factor. Both boys and girls increase the intake of iron as they mature, boys more than girls, and white adolescents slightly more than their black counterparts. Range of intakes was large, and there was no significant correlation between quantity of dietary iron and the percent of transferrin saturation. Norms for dietary intake of iron and percent of transferrin saturation, based on sex, race, and maturity, are presented for use by physicians and nutritionists.

Dietary intakes and plasma concentrations of folate in healthy adolescents.

Dietary intakes of folate and concentrations of plasma folate were obtained from healthy adolescents of families having low or high income. Results were tested statistically in relation to ages and to sex maturity ratings of the subjects. Maturity was a significant factor and age was not. Boys had higher dietary intakes of folate than girls, and family income was not significant. Low folate intakes are in general attributed to incomplete tables of folate content of foods and suggest a need for revision of existing standards. Plasma folate concentrations were higher in girls than in boys at all maturity ratings but both sexes showed decreasing concentrations as they became more mature. The paradox of increased dietary intake associated with decreased plasma folate concentration reflects increased need of folate for cellular manufacture associated with adolescent growth, particularly in boys. Plasma folate concentrations were subnormal in 9.4 percent of boys and 4.7 percent of girls from low-income families. Girls of higher income families had higher plasma folate due to their taking nonprescribed vitamin preparations containing folic acid. Family income did not affect dietary intakes but, either income or cultural pattern indirectly affected plasma folate concentrations. The study demonstrates the value of relating nutritional investigations to maturity ratings.
