    Health problems of adolescence.

    World Health Organization [WHO]. Expert Committee on the Health Problems of Adolescence

    Geneva, World Health Organization, 1965. (Technical Report Series No. 308,) 28 p.

    This is a report of a World Health Organization (WHO) Expert Committee on the Health Problems of Adolescence which met in Geneva from November 3-9, 1964. Adolescence is characterized by a series of biochemical, anatomical and mental changes that are unique to this group which encompasses the age range of about 10-20. This report deals with the primary importance of the family in the life of the adolescent, the influence of the society, and the influence of socioeconomic factors under 1 heading. Also discussed are anatomical, physiological, mental, and emotional aspects of growth and development (such as the development of conseptual thought, search for a sense of personal identity, acquisition of proper sexual attitudes and behavior, etc.). Health needs such as nutrition, physical and mental fitness, the relation of health with school and employment, and health problems such as veneral disease and menstrual disorders are also discussed. The WHO Expert Committee recommends that further attention be given to the mental problems and needs of youth, ways of effective contribution for the establishment and development of school health services be provided for, and time be devoted to the organizational problems of caring for the physically and mentally handicapped individuals.

    Physiology of lactation.


    World Health Organization, (Technical Report Series.). 1965; 22.

    A report of the Scientific Group on the Physiology of Lactation which met in Geneva, December 2-7, 1963, is presented. Major aspects covered include: 1) growth of the mammary gland; 2) milk secretion; 3) biochemical activities of the mammary gland; 4) the physiology of suckling; and 5) factors of human lactation and breast feeding. It is recommended that WHO should: 1) provide grants and research fellowships to enable research workers in the field of lactation to extend their experience by working for a time in other appropriate research centers; 2) support the establishment of laboratories in certain countries for the titration of hormones in cases of normal and abnormal lactation; 3) make contact with organizations engaged in the collection of primate pituitary tissues to obtain their advice and help in organizing the extension of the collection to other parts of the world and in arranging for the preparation of extracts, especially of human prolactin and somatotrophin for international use; 4) make contact with individuals and organizations engaged in the collection of hypothalamic tissue with the object of improving facilities for collection; and 5) encourage studies on human lactation in relation to malnutrition and undernutrition in developing countries.

    Studies on lactation and contraception in WHO's research programme.

    Bernard RM

    JOURNAL OF BIOSOCIAL SCIENCE. 1977; (Suppl 4):113-20.

    WHO (World Health Organization) is planning to undertake 3 different studies concerning lactation and contraception. These studies will attempt 1) to determine the effects, if any, of steroid contraceptives on lactation; 2) to identify and quantify any forms of steriods which may appear in the breast milk of mothers who use steroid contraceptives; and 3) to identify parameters which would help nursing mothers pinpoint ovulation onset. There is considerable controversy among scientists concerning the affects of steroid contraceptives on lactation. WHO proposes to undertake a prospective study assessing the effect of various typis of combined and progestogen only oral steroids as well as injectable preparation on lactation among matched control groups in a number of countries. An effort will be made to minimize an many extraneous variables as possible and to employ uniform procedures and methods in all the countries. In reference to the 2nd study, there is considerable controversy concerning the possible transfer of steroids to maternal breast milk and about the subsequent effect of these steroids on infants who ingest the milk. The WHO study will seek to determine if steroids or their metabolites are present in the breast milk of nursing mothers who take steroid contraceptives. In reference to the 3rd study, if reliable indicators of ovulation resumption among postpartum women can be identified, efforts will be made to develop test kits for home use by nursing mothers.

    A randomized, double-blind study of six combined oral contraceptives.

    World Health Organization [WHO]. Special Programme of Research, Development and Research Training in Human Reproduction. Task Force on Oral Contraceptives

    Contraception. 1982 Mar; 25(3):231-41.

    A randomized, controlled, clinical trial comparing 6 combined oral contraceptives (OCs) with 50 mcg or less of ethinyl estradiol was undertaken in 10 WHO Collaborating Centers for Clinical Research in Human Reproduction. A total of 2430 women entered the trial and were observed for 28,077 woman-cycles. All low-dose combined OCs demonstrated equivalent efficacy with 1-year pregnancy rates of 1-6%. However, discontinuation rates for medical reasons differed significantly between the treatment groups with the preparation containing 20 mcg ethinyl estradiol and that containing 400 mcg norethisterone acetate being associated with higher discontinuation rates due to bleeding disturbances. Even among the preparations which did not differ in discontinuation rates, the reasons for discontinuation did differ. Women receiving norethisterone preparations tended to discontinue because of bleeding disturbances while those receiving the levonorgestrel-containing preparations tended to discontinue because of complaints of nausea and vomiting.
