Linkages between men's wealth status and the ideal number of children: A trend and multilevel analysis of survey data in Nigeria.

Most African societies practice a patriarchal family system that endows a man with authority and dominance in the family and society with a defined role of being the breadwinner of the home. A man is expected to have a great influence in determining the ideal number of children in the family and take a domineering role in decision-making, especially those related to household resource allocation. Therefore, this study examines the relationship between men's wealth status and an ideal number of children. The study used secondary data from the National Demographic Health Survey (NDHS) from 2003 to 2018. The objectives were achieved using descriptive and inferential statistics, including frequency, mean, ANOVA, and multilevel analysis techniques. Wealth status significantly influenced the ideal number of children considering the crude and adjusted regression analysis. After adjusting for individual-level and contextual factors, the odd ratio of ideal number of children was significantly lower among men in the richest categories of the wealth index. Moreover, men with two wives and above, uneducated men, Northern residents, men living in high community family norms, low community family planning, high community poverty, and low community level of education desired a high number of children. The analyses suggest the need for a consideration of community structures to provide lucrative employment for men and would experience an appreciable fertility decline in line with the objectives and targets stated in Nigeria's population policies and programmes.

Child's Risk Attributes at Birth and Infant Mortality Disparities in Nigeria.

Births in avoidable high-risk contexts defined by the interplay of sub-optimal childbearing age, short spacing, and first and high birth order incur elevated risks of childhood death. However, the extent of disparities in risks of dying in infancy vis-à-vis the continuum of non-high-risk and (un)avoidable high-risk attributes at birth as determined by mother's age at childbirth, child spacing, and birth order characteristics is yet to be adequately explored in Nigeria as elsewhere. To fill this gap, chi-square association test and Cox's proportional hazards regression were used to analyze data of 31,260 nationally representative children aged 0-59 months drawn from 2013 Nigeria Demographic and Health Survey. Disparities in infant mortality risks were mainly examined across the spectrum of birth-related risk attributes at birth broadly categorized as no extra high-risk, unavoidable first- order risk and combined avoidable high-risk. The risks of dying in infancy differed significantly by risk attributes to the extent dictated by other confounders. Also, infant mortality risks varied significantly by all moderating factors excluding religion, water source, toilet type and place of delivery. Interventions targeted at reducing avoidable high-risk fertility rate and strengthening health system to provide life-saving care to most-at-risk children would engender rapid improvement in infant survival.

Knowledge and attitudes of primary health care personnel concerning mental health problems in developing countries: a follow-up study.

Within the context of a World Health Organization coordinated collaborative study health workers in six developing countries were assessed 18 months after their training for improvement in their knowledge and attitude towards mental health problems and their management. The approaches to training varied between study areas, but the degree of improvement following the training, was of equal magnitude in all countries. The training process has formalized the recognition by the health workers that treatment of mental health problems is an integral part of their work.

Knowledge and attitudes of primary health care personnel concerning mental health problems in developing countries.

A semi-structured interview for assessing the knowledge and attitude of health workers concerning mental health problems was applied in seven developing country areas within the context of a World Health Organization coordinated collaborative study. The results indicate a lack of basic mental health training associated with a failure to recognize mental health problems, restricted knowledge concerning psychotropic drug therapy, and an inability to visualize practical forms of mental health care which could be introduced at primary care level. The results were used to design appropriate training programs, and the observations will be repeated to assess the effectiveness of training.

On vagrancy and psychosis.

Paradoxically, due to recent mental health legislation, the mentally handicapped of the developed world find themselves in the same situation as the majority of those in the developing world who never had contact with a mental health service. A survey of the literature and of the situation in Egypt and Lesotho suggests marked coincidence of vagrancy and chronic mental illness. In both the developed and developing world, adequate services to support these people are lacking.

The classification of psychiatric disorder. A reliability study in the WHO collaborative study on strategies for extending mental health care.

Altogether 26 psychiatrists and other mental health workers, from Colombia, Brazil, Sudan, Egypt, India and the Philippines tried to reach agreement on the classification of 10 case histories, using the International Classification of Diseases (8th revision). The exercise was part of the WHO Collaborative Study on Strategies for Extending Mental Health Care. Conventions, mistakes, differences of opinion and a lack of rules are discussed as causes for disagreement.
