    Child Malnutrition in Pakistan: Evidence from Literature.

    Asim M; Nawaz Y

    Children. 2018 May 4; 5(5)

    Pakistan has one of the highest prevalences of child malnutrition as compared to other developing countries. This narrative review was accomplished to examine the published empirical literature on children’s nutritional status in Pakistan. The objectives of this review were to know about the methodological approaches used in previous studies, to assess the overall situation of childhood malnutrition, and to identify the areas that have not yet been studied. This study was carried out to collect and synthesize the relevant data from previously published papers through different scholarly database search engines. The most relevant and current published papers between 2000(-)2016 were included in this study. The research papers that contain the data related to child malnutrition in Pakistan were assessed. A total of 28 articles was reviewed and almost similar methodologies were used in all of them. Most of the researchers conducted the cross sectional quantitative and descriptive studies, through structured interviews for identifying the causes of child malnutrition. Only one study used the mix method technique for acquiring data from the respondents. For the assessment of malnutrition among children, out of 28 papers, 20 used the World Health Organization (WHO) weight for age, age for height, and height for weight Z-score method. Early marriages, large family size, high fertility rates with a lack of birth spacing, low income, the lack of breast feeding, and exclusive breastfeeding were found to be the themes that repeatedly emerged in the reviewed literature. There is a dire need of qualitative and mixed method researches to understand and have an insight into the underlying factors of child malnutrition in Pakistan.

    Trends in infant nutrition in Saudi Arabia: compliance with WHO recommendations.

    El Mouzan MI; Al Omar AA; Al Salloum AA; Al Herbish AS; Qurachi MM

    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.

    Anti-tuberculosis drug resistance in the world. Fourth global report. The WHO / IUATLD Global Project on Anti-Tuberculosis Drug Resistance Surveillance, 2002-2007.

    Wright A; Zignol M

    Geneva, Switzerland, World Health Organization [WHO], 2008. [140] p. (WHO/HTM/TB/2008.394)

    This is the fourth report of the WHO/IUATLD Global Project on Anti-Tuberculosis Drug Resistance Surveillance. The three previous reports were published in 1997, 2000 and 2004 and included data from 35, 58 and 77 countries, respectively. This report includes drug susceptibility test (DST) results from 91,577 patients from 93 settings in 81 countries and 2 Special Administrative Regions (SARs) of China collected between 2002 and 2006, and representing over 35% of the global total of notified new smear-positive TB cases. It includes data from 33 countries that have never previously reported. New data are available from the following high TB burden countries: India, China, Russian Federation, Indonesia, Ethiopia, Philippines, Viet Nam, Tanzania, Thailand, and Myanmar. Between 1994 and 2007 a total of 138 settings in 114 countries and 2 SARs of China had reported data to the Global Project. Trend data (three or more data points) are available from 48 countries. The majority of trend data are reported from low TB prevalence settings; however this report includes data from three Baltic countries and 2 Russian Oblasts. Trend data were also available from 6 countries conducting periodic or sentinel surveys (Cuba, Republic of Korea, Nepal, Peru, Thailand, and Uruguay). (excerpt)

    Over-the-counter access, changing WHO guidelines, and contraindicated oral contraceptive use in Mexico.

    Yeatman SE; Potter JE; Grossman DA

    Studies in Family Planning. 2006 Sep; 37(3):197-204.

    This study examines the prevalence of contraindications to the use of oral contraceptives in Mexico by sociodemographic characteristics and by whether this family planning method was obtained with or without a doctor's prescription. Using data on smoking behavior and blood-pressure measurements from the 2000 Mexican National Health Survey, the authors found that, under the 1996 World Health Organization (WHO) medical eligibility guidelines, the prevalence of contraindications is low and that no significant differences in contraindications exist at any level between those who obtain oral contraceptives at clinics and those who obtain them at pharmacies. In 2000, however, WHO substantially revised its criteria regarding the level of hypertension that would constitute a contraindication for oral contraceptive use. Applying the new guidelines, the authors found that 10 percent of pill users younger than 35 and 33 percent aged 35 and older have health conditions that are either relative or absolute (Category 3 or 4) contraindications. The relevance of these findings to the larger debate concerning screening and over-the-counter access to oral contraceptives is discussed. (author's)

    Use of oral contraceptives and hormone replacement therapy in the WHO MONICA project.

    Lundberg V; Tolonen H; Stegmayr B; Kuulasmaa K; Asplund K

    Maturitas. 2004 May 28; 48(1):39-49.

    The aims were to compare menopausal age and the use of oral contraceptives (OC) and hormonal replacement therapy (HRT) between the 32 populations of the WHO MONICA Project, representing 20 different countries. Using a uniform protocol, age at menopause and the use of OC and HRT was recorded in a random sample of 25-64 year-old women attending the final MONICA population cardiovascular risk factor survey between 1989 and 1997. A total of 39,120 women were included. There were wide variations between the populations in the use of OC and HRT. The use of OC varied between 0 and 52% in pre-menopausal women aged 35-44 years, Central and East Europe and North America having the lowest and West Europe and Australasia the highest prevalence rates. Among post-menopausal women between 45 and 64 years, the prevalence of HRT use varied from 0 to 42%. In general, the use of HRT was high in Western and Northern Europe, North America and Australasia and low in Central, Eastern and Southern Europe and China. With the exception of Canada (45 years), the mean age at menopause differed only little (ranging from 48 to 50 years) between the populations. The use of OC and HRT varies markedly between populations, in general following a regional pattern. Whereas, the prevalence rates are mostly similar within a country, there are remarkable differences even between neighbouring countries, reflecting nation-specific medical practice and public attitudes that are not necessarily based on scientific evidence.

    WHO report 2005: TB linked to HIV at alarming levels in Africa.

    Reinhardt E

    UN Chronicle. 2005 Jun-Aug; 42(2):[5] p..

    The battle against tuberculosis (TB) is being successfully fought in most areas of the world, but in Africa the disease has reached alarming proportions with an increasing number of cases and deaths linked to HIV, said the World Health Organization in its WHO Report 2005, Global Tuberculosis Control: Surveillance, Planning, Financing, released on 24 March to coincide with World TB Day. The WHO Report focuses on five principal indicators: incidence, prevalence, deaths, case detection and treatment success. It finds that its prevalence has declined worldwide by more than 20 per cent since 1990 and that incidence rates are falling or stable in all regions except in Africa, where TB rates have tripled since 1990 in countries with high HIV prevalence and continue to rise at 3 to 4 per cent annually.

    Prediction of community prevalence of human onchocerciasis in the Amazonian onchocerciasis focus: Bayesian approach. [Prévisions portant sur la prévalence communautaire de l'onchocercose humaine au niveau du foyer amazonien de l'onchocercose : approche bayésienne]

    Carabin H; Escalona M; Marshall C; Vivas-Martinez S; Botto C

    Bulletin of the World Health Organization. 2003 Jul; 81(7):482-490.

    Objective: To develop a Bayesian hierarchical model for human onchocerciasis with which to explore the factors that influence prevalence of microfilariae in the Amazonian focus of onchocerciasis and predict the probability of any community being at least mesoendemic (>20% prevalence of microfilariae), and thus in need of priority ivermectin treatment. Methods: Models were developed with data from 732 individuals aged515 years who lived in 29 Yanomami communities along four rivers of the south Venezuelan Orinoco basin. The models’ abilities to predict prevalences of microfilariae in communities were compared. The deviance information criterion, Bayesian P-values, and residual values were used to select the best model with an approximate cross-validation procedure. Findings: A three-level model that acknowledged clustering of infection within communities performed best, with host age and sex included at the individual level, a river-dependent altitude effect at the community level, and additional clustering of communities along rivers. This model correctly classified 25/29 (86%) villages with respect to their need for priority ivermectin treatment. Conclusion: Bayesian methods are a flexible and useful approach for public health research and control planning. Our model acknowledges the clustering of infection within communities, allows investigation of links between individual- or community-specific characteristics and infection, incorporates additional uncertainty due to missing covariate data, and informs policy decisions by predicting the probability that a new community is at least mesoendemic.

    Strategies for control of trachoma: observational study with quantitative PCR.

    Solomon AW; Holland MJ; Burton MJ; West SK; Alexander ND

    Lancet. 2003 Jul 19; 362(9379):198-204.

    Background: Antibiotics are an important part of WHO’s strategy to eliminate trachoma as a blinding disease by 2020. At present, who needs to be treated is unclear. We aimed to establish the burden of ocular Chlamydia trachomatis in three trachomaendemic communities in Tanzania and The Gambia with real-time quantitative PCR. Methods: Conjunctival swabs were obtained at examination from 3146 individuals. Swabs were first tested by the qualitative Amplicor PCR, which is known to be highly sensitive. In positive samples, the number of copies of omp1 (a single-copy C trachomatis gene) was measured by quantitative PCR. Findings: Children had the highest ocular loads of C trachomatis, although the amount of pooling in young age groups was less striking at the site with the lowest trachoma frequency. Individuals with intense inflammatory trachoma had higher loads than did those with other conjunctival signs. At the site with the highest prevalence of trachoma, 48 of 93 (52%) individuals with conjunctival scarring but no sign of active disease were positive for ocular chlamydiae. Interpretation: Children younger than 10 years old, and those with intense inflammatory trachoma, probably represent the major source of ocular C trachomatis infection in endemic communities. Success of antibiotic distribution programmes could depend on these groups receiving effective treatment. (author's)

    Hepatitis B in St Petersburg, Russia (1994-1999): incidence, prevalence and force of infection.

    Beutels P; Shkedy Z; Mukomolov S; Aerts M; Shargorodskaya E

    Journal of Viral Hepatitis. 2003 Mar; 10(2):141-149.

    Hepatitis B (HB) is thought to be an expanding health problem in Russia. The incidence of infection was estimated from mandatorily reported HB cases in St Petersburg. The two-sided t-test for independent samples and the LOESS (locally-weighted regression) smoother were used to compare the age at infection for symptomatic, asymptomatic and chronic infections, by gender. The force of infection was estimated from seroprevalence data (907 sera taken in 1999) using a newly developed nonparametric method based on local polynomials, as well as an earlier method based on isotonic regression and kernel smoothers. With the local polynomial method, pointwise confidence intervals (95%) were constructed by bootstrapping. On average, men contracted HB infection at a significantly younger age than women (in 1999, 21.8 vs 22.7 years, respectively). The overall male to female ratio was 1.92. In 1999 the overall incidence almost doubled compared with the preceding years and tripled among the age groups with highest incidence (15–29-year olds: 85% of cases in 1999). The incidence increase was associated with a lower average age at infection (24.1 years in 1994 vs 22.1 years in 1999). The age and gender-specific force of infection estimates generally confirmed the incidence estimates and emphasized the usefulness of local polynomials to do this. Hence HB transmission in St Petersburg occurs mainly in young adults. The dramatic increase of infections in 1999 was probably due to injecting drug use. Without intervention, HB virus is expected to continue to spread rapidly with a greater proportion of female infections caused by sexual transmission. These trends may also provide an indication for HIV transmission. (author's)

    AIDS update.

    ETHIOPIAN MIDWIVES MAGAZINE. 1995; (10):13.

    The Global Program on Acquired Immunodeficiency Syndrome (AIDS), known as GPA, has established a new organization composed of several UN agencies (i.e., WHO, UNICEF, UNDP, UNESCO, UNDFP, and the World Bank). GPA estimates for human immunodeficiency infection (HIV) indicate an increase of 3 million over the last year. Over half of the new infections occurred in women. The sharpest rise has been in the number of AIDS cases; during the last 6 months, the estimated cumulative number has risen from 1 million to 4 million globally. Since the beginning of the pandemic, over 16 million men, women, and children have become infected with HIV. One in every 15 people infected is a child. Almost one-fourth of the total, about 4 million, have developed AIDS. The GPA Management Committee Meeting (GMC) in May released the following information: 1) every day 5000 more people are infected with HIV; 2) sub-Saharan Africa remains the most heavily affected with two-thirds of the total infections; 3) the epidemic is spreading most rapidly in India, Thailand, Vietnam, and Cambodia; 4) there has been an increase, from 30,000 to 250,000, in the number of AIDS cases in the past year in south and southeast Asia; and 5) prevalence rates as high as 25% among military recruits, and 8% among pregnant women, are being reported in parts of northern Thailand. Once the epidemics in African countries have matured, over two-thirds of the new infections occur in persons under 24 years of age; almost half of the new adult cases are women. Unless action is taken at least 30-40 million people will be infected by the end of the decade.

    Evaluation of the WHO clinical case definition for AIDS in rural Zaire.

    De Cock KM; Colebunders R; Francis H; Nzilambi N; Laga M; Ryder RW; Bondjobo M; McCormick JB; Piot P

    AIDS. 1988 Jun; 2(3):219-21.

    In many areas of Africa where AIDS is endemic, facilities for laboratory diagnosis are too limited to reliably diagnose opportunistic infections. Therefore, the World Health Organization defined a clinical case definition of AIDS in which 2 major signs and at least 1 minor sign must be present to diagnose AIDS. The major signs are: weight loss greater than 10%, diarrhea for more than 1 month, and prolonged fever for more than 1 month. The minor signs are: persistent cough for more than 1 month, generalized pruritic dermatitis, recurrent herpes zoster, oropharyngeal candidiasis, chronic disseminated herpes simplex, and generalized lymphadenopathy. (The presence of Kaposi's sarcoma or cryptococcal meningitis are sufficient by themselves for a diagnosis of AIDS.) 72 patients in 4 hospitals in Equateur Province of Zaire were used to test the reliability of the clinical case definition. 21 (29%) of the patients were HIV seropositive, and 22 (32%) fulfilled the clinical criteria. From these data the sensitivity of the case definition was 52%, specificity was 78%, positive predictive value was 50%, and negative predictive value was 80%. Since positive predictive value rises with prevalence and HIV infection is maximal in the 20-40 age group, restricting the case definition to this age group would increase its predictive value. Exclusion of patients with tuberculosis would reduce the number of false positive results.

    The prevalence method.

    Bongaarts J

    In: Addendum. Manual IX: The methodology of measuring the impact of family planning programmes on fertility, by the Population Division of the Department of International Economic and Social Affairs of the United Nations. New York, New York, United Nations, 1986. 9-14. (Population Studies No. 66; ST/ESA/SER.A/66/Add.1)

    This chapter describes and applies a new methodology for estimating the fertility impact of contraception obtained through a family planning program. This approach is called the prevalence method because the principal data required for its application are estimates of the prevalence of contraceptive use at a given point in time. It is the objective of the prevalence method to estimate the number of births averted as well as the reduction in the crude birth rate that results form the use of program contraception. A single application of the procedure produces these estimates for 1 year, but repeated applications for different years can yield a time-series of births averted or other impact measures. The procedure for calculating births averted by program users consists of 6 parts to obtain, consecutively, estimates of: natural fertility, potential fertility, fertility impact of program use, births averted, birth rate impact, and method-specific results. Each of these steps is described in some detail. This new approach provides a simple and straightforward alternative to existing methods for estimating the gross fertility impact of program contraception. In contrast to several of the other procedures, the prevalence method does not require detailed input data on numbers of past acceptors and continuation rates. Instead, estimates of the prevalence of program and non-program contraception by age and method are required as principal input data. While such data were rarely available in the past, prevalence estimates are now routinely obtained from national surveys in many developing countries, thus making the application of the prevalence method possible.

    A vasectomy education program: implications from survey data.

    Mullen P; Reynolds R; Cignetti P; Dornan D

    Family Coordinator. 1973 Jul; 22(3):331-8.

    Data collected on behalf of the Planned Parenthood/World Population (PPWP) affiliate to be used in planning a vasectomy education program came from a survey of 387 men and women in Hayward, California, to ascertain the levels of knowledge and prevalence of vasectomy and attitudes toward the operation. The sample was comprised of men and women in 3 income categories, and households were not preselected on a random basis. The survey instrument was a 1-page set of questions, primarily of the closed-ended type which the respondent completed in the presence of the interviewer. The major findings were: 1) PPWP was not identified as a source of aid; 2) most men and women have discussed vasectomy with their spouses; 3) men and women are influenced by attitudes and practices of others with regard to vasectomy; 4) physicians are seen as the main source of information about vasectomy; 5) irreversibility is the major concern of the men and women; and 6) eligible couples can be reached only by a community-side education program. Implications of the survey for a community education program are put into concrete, programmatic terms, indicating lines of direction, points of departure, and crucial ideas sometimes overlooked in service programs. It is concluded that in all areas of a community education program vasectomy should be presented as 1 or a range of alternatives, thus assuring the couple that does elect vasectomy that they really did make a free choice.

    Some health-related aspects of fertility.

    World Health Organization [WHO]

    [Unpublished] 1983. Presented at the International Conference on Population, 1984, Expert Group on Fertility and Family, New Delhi, January 5-11, 1983. 22 p. (IESA/P/ICP. 1984/EG.I/8)

    The World Health Organization (WHO) has been studying several national surveys with regard to certain health related aspects of fertility. The primary purpose of these studies was to stimulate the use of data by the national health authorities for an improved care system for maternal and child health, including family planning. Some preliminary results are reported in this discussion, in particular those relating to contraception, the reproductive health of adolescents, infertility and subfecundity, and breastfeeding. The national surveys concerned are those of Bangladesh, Indonesia, the Republic of Korea, the Philippines, and Sri Lanka. The methods of analysis were simple and traditional, except for 2 points: some of the data had to be obtained by additional tabulation of the raw data tapes and/or the recode tapes since the standard tabulations of the First Country Reports did not include the needed information; and Correspondence Analysis was used in an effort to stimulate and facilitate the use of the findings for improvements of national health programs. Methods of contraception vary widely, from 1 country to another and by age, parity, and socioeconomic grouping. The younger women tend to choose more effective modern methods, such as oral contraception (OC); the older women, i.e., those over age 35, tend to seek sterilization, if available. It is evident that the historical development of family planning methods has greatly influenced the current "mix" of methods and so has the current supply situation and the capacity of the health care system (particularly in regard to IUD insertions and sterilizations. Use of contraception among adolescents to postpone the 1st birth was practically unknown. The risk of complications at pregnancy and childbirth, including maternal and infant death, is known to be particularly high for young mothers, and the results clearly showed that the infant mortality rate is highest for the youngest mothers. All the women who suffer from infertility do not recognize their condition, but the limited data still point to the need to consider the health needs of women who suffer from unwanted fecundity impairments. This may require medical intervention to cure infections or the offer of relevant sexual counseling. Some infecundity may require the improvement of nutritional and personal hygienic levels before meaningful achievements are made. The prevalence of breastfeeding has declined in some population groups, and the consequences can be expected to be deleterious and to involve serious increases in specific morbidity and mortality.
