Annals of Saudi Medicine. 2009 Jan-Feb; 29(1):20-3.BACKGROUND AND OBJECTIVE: The WHO recommends exclusive breastfeeding in the first 6 months of life. Our objective was to evaluate trends in infant nutrition in Saudi Arabia and the degree of compliance with WHO recommendations. SUBJECTS AND METHODS: A nationwide nutritional survey of a sample of Saudi households was selected by the multistage probability sampling procedure. A validated questionnaire was administered to mothers of children less than 3 years of age. RESULTS: Of 5339 children in the sample, 4889 received breast milk at birth indicating a prevalence of initiation of 91.6%. Initiation of breastfeeding was delayed beyond 6 hours after birth in 28.1% of the infants. Bottle feeding was introduced by 1 month of age to 2174/4260 (51.4%) and to 3831/4260 (90%) by 6 months of age. The majority of infants 3870/4787 (80.8%) were introduced to "solid foods" between 4 to 6 months of age and whole milk feedings were given to 40% of children younger than 12 months of age. CONCLUSIONS: The current practice of feeding of Saudi infants is very far from compliance with even the most conservative WHO recommendations of exclusive breastfeeding for 4 to 6 months. The high prevalence of breastfeeding initiation at birth indicates the willingness of Saudi mothers to breastfeed. However, early introduction of complementary feedings reduced the period of exclusive breastfeeding. Research in infant nutrition should be a public health priority to improve the rate of breastfeeding and to minimize other inappropriate practices.
[Unpublished] 1994. Presented at the 1994 Southern Demographic Association Annual Meeting, Atlanta, Georgia, October 20-22, 1994. , 40, 10 p.This analysis uses two different measures of the parity progression ratio (PPR) in a period analysis of fertility and the impact of the family planning program on fertility in Kenya. The study is part of a UNFPA project including 14 other developing countries. Survey data from the 1978 World Fertility Survey and the 1989 Demographic and Health Survey provide data for the analysis. PPR is calculated first by a life table technique using birth probabilities specific for parity and birth interval in a period. PPR in the second calculation is an age-parity-adjusted progression based on schedules produced by Feeney. Results are presented for marital unions, first birth, birth intervals, parity progression, the impact of the family planning program, and socioeconomic differences. The results show an increase in age at first birth during the 1970s and 1980s. There is also a decrease in first births among adolescents between the 1960s and the late 1980s. A new finding is a reverse trend; a 1 year decrease in median age at first marriage occurred in urban areas between 1981-85 and 1985-89. The decrease is attributed to an increase in adolescent marriage in the late 1980s. By the 1980s families were being built at older ages, and births were being spaced farther apart. Adolescent first births and high parity births declined between the 1960s and 1980s. The trends reflect a clear and consistent pattern of modernization and better health with decreased population growth. Fertility is expected to reach replacement level soon. The family planning program contributed to the decline in progression to 6th and higher parities by 5% over 30 years. Higher marriage age and later age at first birth were related to higher educational status, although rural marriage age was higher by 0.7 years than urban marriage age. There was a high rate of adolescent marital unions, particularly informal unions, in urban areas. Teenage births were higher in rural areas. Urban women had a lower PPR in all birth orders than rural women. Median birth interval did not vary with educational level. A shorter than 24 month birth interval for 2nd and low order births occurred among the most educated and those in urban areas.
PID risk for IUD users highest in first 20 days after insertion; risk then falls sharply and remains low.
Family Planning Perspectives. 1992 Sep-Oct; 24(5):235-6.Researchers analyzed data on 22,908 women obtained from randomized WHO studies from 23 countries to determine whether the IUD increases the risk of pelvic inflammatory disease (PID). 35% of the women used the TCu220C IUD, 39% other copper releasing IUDs, 16% a hormonal IUD, and 9% the Lippes Loop. The overall PID incidence rate was 0.4% of all IUD insertions or 1.6 cases/1000 woman years. The incidence was greatest during the 1st 20 days after insertion (9.7 cases/1000 women years) and then declined to 1.4/1000 woman years. In fact, the risk of PID was >6 times greater within 20 days after insertion than it was >20 days after insertion. This high risk immediately after insertion was evident in every region where PID existed, at all insertion times, and in all age groups. The higher risk within the 20 days after insertion was attributed to contamination of the uterus during insertion. Women who had an IUD inserted after 1980 experienced PID 50% less often than those who had had it inserted earlier, e.g., the rate ratio for 1977-80 was 1.5 but was 0.5 for 1981-83 and 0.34 for 1984 and after. This may have been due to physicians being more aware of contraindications for IUD use, particularly past infection with sexually transmitted diseases )STDs). The rate ratio was higher in Africa (2.6) than it was in Europe (1) but lower in Asia (0.46) and in the Americas (0.39). None of the subjects in China experienced PID. Older women were at lower risk of PID than 15-24 year olds (0.44 for 25-29 year olds, 0.38 for 30-34 year olds, and 0.35 for =or> 35 year olds). The researchers believed the higher risk life styles of the younger group accounted for this difference. Risk of PID decreased with family size (2.5 for 0 children, 0.56 for 2 children, and 0.39 for at least 4 children). The risk of PID did not differ with IUD type. The researchers concluded that the major determinant of PID is exposure to an STD rather than type of IUD.
The sex and age distributions of population. The 1990 revision of the United Nations global population estimates and projections.
New York, New York, United Nations, 1991. viii, 391 p. (Population Studies No. 122; ST/ESA/SER.A/122)This statistical report includes the estimated and projected age distribution of the population based on high, medium, and low variants for 152 countries with populations greater than 300,000 between 1950 and 2025 in 5-year intervals. A world total as well as by continents and subregions are available along with the spatial groups; least developed countries, less developed regions (excluding China), the Economic Commission for Africa, Latin America and the Caribbean, Asia, and the Pacific, Western Asia, and sub-Saharan Africa. Grouped data reflect countries with populations both greater than and less than 300,000. This revision was begun in 1988 and completed in 1990 by the UN Population Division of the International Economic and Social Affairs Department in conjunction with other UN regional commissions and the Statistical Office. A discussion of methods and data used for these estimates, a summary of findings, and selected demographic indicators will be available in World Population Prospects, 1990, and in summary form in the UN World Population Chart, 1990. A magnetic tape and diskettes of these data are available on request for purchase.
POPULATION BULLETIN OF THE UNITED NATIONS. 1989; (27):108-24.This paper reviews recent new trends in population structure in the world and its major regions in order to access the determinants of those trends and explore issues regarding the recent and projected changes in the age structure of population and the relationships of those changes to social and economic development. In particular, the paper compares the change in age structure projected by the Population Division of the UN Secretariat in its most recent 3 series--namely, those completed in 1984, 1986, and 1988. By and large, the most recent UN assessment projects that a larger proportion of the world population will be aged 60 and over in 2000 and 2025 than was previously estimated. Those changes in projections can be observed for the world and for the more developed countries as a whole, and for the regions of Africa, Latin America, Northern America, East Asia, Europe, and Oceania. While the recommendations of the International Conference on Population called attention to the importance of changes in population structure, this paper recommends urgent government action in planning social programs for the aged because of the greater eminence of population aging in many settings. The case of Japan is used to illustrate the growing importance of increases in life expectancy as a determinant of age structure changes (in relation to fertility decline), a point that is reinforced through a cruder decomposition of UN estimates and projections for several European countries.
