    PIP: The population explosion has been abating since the 2nd half of the 1960s. The birth rate of the 3rd World dropped from 45/1000 during 1950-55 to 31/1000 during 1985-90. From the 1st half of the 1960s to the 1st half of the 1980s the total fertility of such countries dropped from 6.1 to 4.2 children/woman. In Taiwan, Singapore, Hong Kong, South Korea, and Malaysia living standards improved as a result of industrialization, and fertility decreased significantly. In Sri Lanka, China, North Vietnam, and Thailand the drop of fertility is explained by cultural and religious factors. In 1982 about 78% of the population of developing countries lived in 39 states that followed an official policy aimed at reducing the population. Another 16% lived in countries supporting the concept of a desired family size. However, World Bank data showed that in the mid-1980s in 27 developing countries no state family planning (FP) programs existed. India adopted an official FP program in 1952, Pakistan followed suit in 1960, South Korea in 1961, and China in 1962. In Latin America a split policy manifested itself: in Brazil birth control was rejected, only Colombia had a FP policy. In 1986 the governments of 68 of 131 developing countries representing 3.1 billion people considered the number of children per woman too high. 31 of these countries followed concrete population control policies. On the other hand, in 1986 24 countries of Africa with 40% of the continent's population took no measures to influence population growth. In Latin America and the Caribbean 18 of 33 countries were idle, except for Mexico that had a massive state FP program. These programs also improve maternal and child health with birth spacing of at least 2 years, and the prevention of pregnancies of too young women or those over 40. The evaluation of rapidly spreading FP programs in the 1970s was carried out by the World Fertility Survey in 41 countries. The impact of FP programs was more substantial than socioeconomic factors. Contraceptive use increased in Mexico from 13% in 1973 to 41% in 1978 among women of fertile age. According to 1984 and 1988 UN data modern methods of contraception were used by 70% of women in China, 60-65% in Southeast Asia, Costa Rica, and Puerto Rico. In contrast, less than 5% used them in most countries of Africa, 15-20% in West Asia, 25-30% in South Asia, and 40% in Latin America. The pill was the most popular method. From the early 1980s in South and East Asia 1/5 of women got sterilized after attaining the desired family size. Less than 10% of women used IUDs in developing countries. FP programs have benefited from higher education levels and economic incentives and sanctions and exemplified in Singapore, China, South Korea, Thailand, and Taiwan.

    Rapid economic development and population growth, inadequate infrastructure and expertise, and land scarcity make the management of municipal solid waste become one of Malaysia's most critical environmental issues. The study is aimed at evaluating the generation, characteristics, and management of solid waste in Malaysia based on published information. In general, the per capita generation rate is about 0.5-0.8 kg/person/day in which domestic waste is the primary source. Currently, solid waste is managed by the Ministry of Housing and Local Government, with the participation of the private sector. A new institutional and legislation framework has been structured with the objectives to establish a holistic, integrated, and cost-effective solid waste management system, with an emphasis on environmental protection and public health. Therefore, the hierarchy of solid waste management has given the highest priority to source reduction through 3R, intermediate treatment and final disposal.

    Most of the developing countries have solid waste management problems. Solid waste strategic planning requires accurate prediction of the quality and quantity of the generated waste. In developing countries, such as Malaysia, the solid waste generation rate is increasing rapidly, due to population growth and new consumption trends that characterize society. This paper proposes an artificial neural network (ANN) approach using feedforward nonlinear autoregressive network with exogenous inputs (NARX) to predict annual solid waste generation in relation to demographic and economic variables like population number, gross domestic product, electricity demand per capita and employment and unemployment numbers. In addition, variable selection procedures are also developed to select a significant explanatory variable. The model evaluation was performed using coefficient of determination (R(2)) and mean square error (MSE). The optimum model that produced the lowest testing MSE (2.46) and the highest R(2) (0.97) had three inputs (gross domestic product, population and employment), eight neurons and one lag in the hidden layer, and used Fletcher-Powell's conjugate gradient as the training algorithm.

  9. A macroscopic approach to demography
    Smith JD
    J Math Biol, 2004 Jan;48(1):105-18.
    PMID: 14685774
    A canonical/lognormal model for human demography is established, specifying the net maternity function and the age distribution for mothers of new-borns using a single macroscopic parameter vector of dimension five. The age distribution of mothers is canonical, while the net maternity function normalizes to a lognormal density. Comparison of an actual population with the model serves to identify anomalies in the population which may be indicative of phase transitions or influences from levels outside the demographic. Tracking the time development of the parameter vector may be used to predict the future state of a population, or to interpolate for data missing from the record. In accordance with classical theoretical considerations of Backman, Prigogine, et al., it emerges that the logarithm of a mother's age is the most fundamental time variable for demographic purposes.

  10. Fulltext Geospatial analysis of distribution of community pharmacies and other health care facilities providing minor ailments services in Malaysia
    Tew MM, Hatah E, Arif F, Abdul Wahid MA, Makmor-Bakry M, Abdul Maulad KN
    J Pharm Policy Pract, 2021 Feb 24;14(1):24.
    PMID: 33627199 DOI: 10.1186/s40545-021-00308-9
    BACKGROUND: Minor ailments are defined as common, self-limiting, or uncomplicated conditions that may be diagnosed and managed without a medical intervention. Previous studies reported that pharmacists were able to help patients self-manage minor ailments that led to a reduction of health care burden in other facilities. Nevertheless, public access to community pharmacy and other health care facilities offering services for minor ailments has not yet been explored in Malaysia. Hence, this study aims to determine population access to the above-mentioned services.

    METHOD: According to the reported practice address in 2018, the spatial distribution of health care facilities was mapped and explored using the GIS mapping techniques. The density of health care facilities was analyzed using thematic maps with hot spot analysis. Population to facility ratio was calculated using the projection of the population growth based on 2010 census data, which was the latest available in the year of analysis.

    RESULTS: The study included geographical mapping of 7051 general practitioner clinics (GPC), 3084 community pharmacies (CP), 139 public general hospitals (GHs) and 990 public primary health clinics (PHC). The health care facilities were found to be highly dense in urban areas than in the rural ones. There were six districts that had no CP, 2 had no GPC, and 11 did not have both. The overall ratio of GPC, CP, GH, and PHC to the population was 1:4228, 1:10,200, 1:223,619 and 1:31,397, respectively. Should the coverage for minor ailment services in public health care clinics be extended to community pharmacies, the ratio of facilities to population for each district would be better with 1:4000-8000.

    CONCLUSIONS: The distribution of health care facilities for minor ailment management in Malaysia is relatively good. However, if the scheme for minor ailments were available to community pharmacies, then the patients' access to minor ailments services would be further improved.

  11. Comparison of Intrinsic Rate of Different House Fly Densities in a Simulated Condition: A Prediction for House Fly Population and Control Threshold
    Ong SQ, Ahmad H, Jaal Z, Rus A, Fadzlah FH
    J Med Entomol, 2017 Jan;54(1):24-29.
    PMID: 28082628 DOI: 10.1093/jme/tjw140
    Determining the control threshold for a pest is common prior to initiating a pest control program; however, previous studies related to the house fly control threshold for a poultry farm are insufficient for determining such a threshold. This study aimed to predict the population changes of house fly population by comparing the intrinsic rate of increase (rm) for different house fly densities in a simulated system. This study first defined the knee points of a known population growth curve as a control threshold by comparing the rm of five densities of house flies in a simulated condition. Later, to understand the interactions between the larval and adult populations, the correlation between larval and adult capacity rate (rc) was studied. The rm values of 300- and 500-fly densities were significantly higher compared with the rm values at densities of 50 and 100 flies. This result indicated their representative indices as candidates for a control threshold. The rc of larval and adult populations were negatively correlated with densities of fewer than 300 flies; this implicated adult populations with fewer than 300 flies as declining while the larval population was growing; therefore, control approaches should focus on the immature stages. The results in the present study suggest a control threshold for house fly populations. Future works should focus on calibrating the threshold indices in field conditions.

  14. Effects of juvenile hormone analogs on new reproductives and colony growth of Pharaoh ant (Hymenoptera: Formicidae)
    Lim SP, Lee CY
    J Econ Entomol, 2005 Dec;98(6):2169-75.
    PMID: 16539147
    Two juvenile hormone analogs (JHAs), pyriproxyfen and S-methoprene, were impregnated into dried tuna fish and fed to colonies of Monomorium pharaonis (L.) at very low concentrations (1.0, 2.0, 3.0, 4.0, and 5.0 microg/ml). Its effects on the production of sexuals and colonial growth were observed. Colonies treated with pyriproxyfen yielded sexuals with physical abnormalities. Both female and male sexuals developed bulbous wings, decreased melanization, and died shortly after emergence. Sexuals emerged from colonies treated with S-methoprene did not possess anomalous characteristics. Both pyriproxyfen and S-methoprene did not have significant effects on colonial growth because of the low concentrations of the baits. A commercial bait containing 0.3% S-methoprene (Bioprene-BM) also was evaluated for its efficacy on Pharaoh's ant colonies. Results showed that Pharaoh's ant colonies succumbed to the lethal effects of S-methoprene. Colony members were reduced significantly. Production of queens also decreased significantly in treated colonies and treated queens were unable to lay eggs. JHAs are slow acting and eliminate ant colonies at a relatively slow rate. At low concentrations, pyriproxyfen recorded baffling results, i.e., bulbous wings and demelanized exoskeleton, and it is vital that further studies are initiated to solidify these findings.

    Zin T, Mudin KD, Myint T, Naing DKS, Sein T, Shamsul BS
    WHO South East Asia J Public Health, 2013 Jan-Mar;2(1):6-11.
    PMID: 28612817 DOI: 10.4103/2224-3151.115828
    BACKGROUND AND OBJECTIVES: Water and sanitation are major public health issues exacerbated by rapid population growth, limited resources, disasters and environmental depletion. This study was undertaken to study the influencing factors for household water quality improvement for reducing diarrhoea in resource-limited areas.

    MATERIALS AND METHODS: Data were collected from articles and reviews from relevant randomized controlled trials, new articles, systematic reviews and meta-analyses from PubMed, World Health Organization (WHO), United Nations Children's Fund (UNICEF) and WELL Resource Centre For Water, Sanitation And Environmental Health.

    DISCUSSION: Water quality on diarrhoea prevention could be affected by contamination during storage, collection and even at point-of-use. Point-of-use water treatment (household-based) is the most cost-effective method for prevention of diarrhoea. Chemical disinfection, filtration, thermal disinfection, solar disinfection and flocculation and disinfection are five most promising household water treatment methodologies for resource-limited areas.

    CONCLUSION: Promoting household water treatment is most essential for preventing diarrhoeal disease. In addition, the water should be of acceptable taste, appropriate for emergency and non-emergency use.

  16. Use of sterols and linear alkylbenzenes as molecular markers of sewage pollution in Southeast Asia
    Thomes MW, Vaezzadeh V, Zakaria MP, Bong CW
    Environ Sci Pollut Res Int, 2019 Nov;26(31):31555-31580.

    Southeast Asia has undergone rapid developments in terms of urbanization, economic and population growth. The progress in sewerage treatment infrastructure has not kept pace with such developments. The inadequacy and inefficiency of sewerage systems has prompted the release of untreated sewage into the aquatic environment of Southeast Asia causing many waterborne illnesses since surface water is utilized for recreational, agricultural and aquaculture purposes and, above all, as a source of water intake in Southeast Asia. This paper will review the current data on molecular markers of sewage pollution including sterols and linear alkylbenzenes (LABs) in Southeast Asian aquatic environment to clarify the state of sewage pollution and the competence of sewage treatment plants (STPs) in this area. Despite the importance of sewage pollution research in the region, the number of studies using molecular markers to trace the sources of sewage pollution is limited. So far, indicators of sewage pollution have been investigated in aquatic environments of Indonesia, Vietnam, Malaysia, the Philippines, Thailand, Cambodia and Brunei among Southeast Asian countries. The concentrations and diagnostic ratios of faecal sterols and LABs show the release of untreated and primary treated urban waste into water bodies of these countries. Further studies are required to fill the data gaps in Southeast Asia and come to a better understanding of the trends of sewage pollution in this part of the world. Graphical abstract.

  17. Relationship between rainfall and Aedes larval population at two insular sites in Pulau Ketam, Selangor, Malaysia
    Wee LK, Weng SN, Raduan N, Wah SK, Ming WH, Shi CH, et al.
    Southeast Asian J Trop Med Public Health, 2013 Mar;44(2):157-66.
    PMID: 23691624
    Two insular settlements (Kampung Pulau Ketam and Kampung Sungai Lima) were selected to study the population dynamics of Aedes aegypti and Aedes albopictus mosquitoes, vectors of dengue and chikungunya infections. Ovitrap surveillance was conducted between October 2007 and October 2008. There was an inverse negative association between ovitrap index and rainfall at the time of collection, probably because rainfall increased the number of available oviposition sites. Rainfall and ovitrap index were positively associates the 25th day after rainfall occurred. A minor, second peak was observed from the 38th to the 42nd day. The first peak was consistent with the minimum 18-day period between the hatching of eggs to the first oviposition. The second minor peak could be due to the second gonotrophic cycle of the female mosquitoes. Rainfall is an important environmental factor associated with Aedes breeding at the study sites.

    PMID: 1342763
    One of the main characteristics of urbanization in Asia is the very rapid increase in population movement from rural to urban centers. This phenomenon has led to changing population structure, its composition and lifestyles in the cities and its fringes. As a consequent of population pressure on urban system and infrastructure, compounded by the nature of the composition of the in-migrant population, the urban concentrates are faced with several social and socio-economic problems. Although there has been a lot of interests among researchers to study the causes and effects or urbanization, there is a vacuum in the area of health implications. Planners and administrators usually give priority to the physical aspects of the urban and urbanities. Social problems and health implications thereof receives very little attention either at the level of administration or research. This paper therefore is a brave attempt to focus and draw some attention to this neglected area by looking at selected social problems and the health consequences.
