SCN News. 2002 Dec; (25):4-30.This paper addresses the most common nutrition and health problems in turn, assessing the extent of the problem; the impact of the condition on overall development, and what programmatic responses can be taken to remedy the problem through the school sys- tern. The paper also acknowledges that an estimated 113m children of school-age are not in school, the majority of these children living in Sub-Saharan Africa and South-East Asia. Poor health and nutrition that differentially affects this population is also discussed. (excerpt)
Studies in Family Planning. 2003 Jun; 34(2):87-102.Legal abortions are authorized medical procedures, and as such, they are or can be recorded at the health facility where they are performed. The incidence of illegal, often unsafe, induced abortion has to be estimated, however. In the literature, no fewer than eight methods have been used to estimate the frequency of induced abortion: the “illegal abortion provider survey,” the “complications statistics” approach, the “mortality statistics” approach, self-reporting techniques, prospective studies, the “residual” method, anonymous third party reports, and experts’ estimates. This article describes the methodological requirements of each of these methods and discusses their biases. Empirical records for each method are reviewed, with particular attention paid to the contexts in which the method has been employed successfully. Finally, the choice of an appropriate method of estimation is discussed, depending on the context in which it is to be applied and on the goal of the estimation effort. (author's)
New York, New York, United Nations, 1992. viii, 400 p. (ST/ESA/SER.A/128)Available child mortality data are provided since the 1960s for 82 developing countries, arranged alphabetically, with a population of >1 million. The scope and methodology of the data, the main findings, a guide to the notation and layout of the database, and country specific profiles are included. Available data are included from many different sources without adjustment; graphs are provided. There is a brief discussion of the nature of child mortality and the methods used to measure it such as the crude death rate, age specific death rates, the infant mortality rate, <5 mortality, mortality 1-5 years, and model life tables for age specific child mortality. There is also discussion of the various data sources and estimation methods: vital registration data, prospective surveys, household surveys, prospective sample surveys, surveillance systems, retrospective questions in censuses and surveys, questions on recent household deaths by age, Brass method questions to whom on aggregate number of children born or dead, questions on women's most recent birth and survival, and maternity histories. Commentary is provided on the common index approach and the intersurvey change approach to evaluation of child mortality estimates. There is not 1 best method for measuring mortality. Countries with the most complete reporting of vital registration data are Hong Kong, Israel, Mauritius, Puerto Rico, and Singapore. Countries with incomplete data which does not provide a good measure of child mortality are Egypt, El Salvador, Guatemala, Jamaica, and Trinidad and Tobago. Brass estimates which agree with vital registration data include the following countries: Costa Rica, Cuba, Kuwait, and Peninsular Malaysia. Indirect estimates which confirm vital registration data pertain to Chile and Uruguay. Brass questions provide satisfactory results in Costa Rica, Cuba, Egypt, El Salvador, Guatemala, Jamaica, Sri Lanka, and Trinidad and Tobago. Underestimates are expected for Argentina and Egypt. Indirect methods applied to census data provide good estimates for 23 countries, indirect methods applied to survey data yields good estimates for 21 countries, and direct calculations from maternity histories provide good estimates for 20 countries. 17 countries have poor results from maternity histories alone. Child mortality may have fallen by >50% in developing countries between 1960-85.
A prospective multicentre trial of the ovulation method of natural family planning. Pt. 2. The effectiveness phase.
Fertility and Sterility. 1981 Nov; 36(5):591-98.A 5 country prospective study was undertaken to determine the effectiveness of the ovulation method of natural family planning. 869 subjects of proven fertility from 5 centers (Auckland, Bangalore, Dublin, Manila, and San Miguel) entered the teaching phase of 3-6 cycles; 765 (88%) completed the phase. 725 subjects entered a 13-cycle effectiveness phase and contributed 7514 cycles of observation. The overall cumulative net probability of discontinuation for the effectiveness study after 13 cycles was 35.6%, 19.6% due to pregnancy. Pregnancy rates per 100 woman-years calculated using the modified Pearl index were as follows: conscious departure from the rules of the method, 15.4; inaccurate application of instructions, 3.5; method failure, 2.8; inadequate teaching, 0.4; and uncertain, 0.5. Cycle characteristics included: 1) average duration of the fertile period of 9.6 days, 2) mean of 13.5 days occurred from the mucus peak to the end of the cycle, 3) a mean of 15.4 days of abstinence was required, and 4) a mean of 13.1 days of intercourse was permitted. Almost all women were able to identify the fertile period by observing their cervical mucus but pregnancy rates ranged from 27.9 in Australia and 26.9 in Dublin to 12.8 in Manila. Continuation was relatively high ranging from 52% in Auckland to 74% in Bangalore.
