    This analysis demonstrates the application of a data duplication technique in linear regression with censored observations of the waiting time to third pregnancy ending in two outcome types, using data from Malaysia. The linear model not only confirmed the results obtained by the Cox proportional hazards model, but also identified two additional significant factors. The method provides a useful alternative when Cox proportionality assumption of the hazards is violated.

    The intervals between pregnancies have important effects on fertility and maternal and infant health outcomes. This study uses linear regression with censored observation to assess the determinants of the waiting time to third pregnancy. The analysis is applied to data from the Second Malaysian Family Life Survey consisting of 1172 women who had their second delivery ending in a live birth. Contraceptive use, age of the woman, duration of breast-feeding, length of previous pregnancy interval and education of the woman all affect the waiting time to third pregnancy significantly.

    This study investigates the unusual relationship between breastfeeding and waiting time to conception in Malaysia as reported in Goldman et al. (1987). Using data from the Malaysian World Fertility Survey (MWFS), Goldman and her colleagues (1987) find that noncontracepting Malaysian women have an unusually long waiting time to conception, given their relatively short durations of breastfeeding. This study provides a similar analysis using data from the Malaysian Family Life Survey (MFLS) and finds a more typical relationship. I conclude that the distinction between full and partial breastfeeding made to respondents of the MFLS probably led to more reliable responses to questions about breastfeeding duration, especially for women who breastfeed for long durations.

    Analyses previously reported, based on data from the World Fertility Survey (WFS), are replicated here with data from the Malaysian Family Life Survey. Comparison of results, when data limitations inherent in the World Fertility Surveys are reproduced or relaxed, suggests that these limitations cause little distortion, and thus bolsters confidence in the validity of results based on WFS data in which these limitations are inescapable. Generalizations based on the present investigation and on the body of previous work that it tends to validate are presented. Most significantly, these include the greater importance of both breastfeeding and birth spacing under generally unfavorable conditions, the variability of durations to which some benefit of continued breastfeeding persists, and the observation that the great majority of birth-spacing effects operate through some mechanism other than the association of breastfeeding with birth interval lengths.
    PIP: Analyses previously reported, based on data from the World Fertility Survey (WFS) are replicated with data from the Malaysian Family Life Survey, based on a stratified probability sample for 1,262 ever-married women 50 years of age in Peninsular Malaysia. Comparison of the results, when data limitations inherent in the WFS are reproduced or relaxed, suggests that these limitations cause little distortion, and thus bolsters confidence in the validity of results based on WFS data in which these limitations are inescapable. Generalizations based on the present investigation and on the body of previous work that it tends to validate are presented. The greater importance of both breastfeeding and birth spacing under generally unfavorable conditions becomes clear. The relationship between breastfeeding and survival for all births, as well as for the last 2 births, emphasized in this model, has a logit coefficint significant at the .01 level for the 1st month of life as well as the period from birth to 1 year. The durations to which some benefit of continued breastfeeding persists, are variable. In countries where the situation generally is more favorable to child survival, as indicated by rates of infant mortality, breastfeeding's positive effects on child survival are less significant. Breastfeeding promotion and continuation should be the goal especially for programs operating among very poor groups. The great majority of birth spacing effects operate through some mechanism other than the association of breastfeeding with birth interval lengths, as indicated by the fact that significant survival advantages are often associated with birth spacing after controlling for breastfeeding

    INTRODUCTION: Short Interpregnancy interval (IPI) is defined as the interval between the live birth outcome and the next pregnancy conception of less than 24 months. It has been linked to adverse maternal and perinatal outcomes. The objective of this study was to determine the prevalence and the predictors of short IPI among antenatal mothers.

    METHODS: A cross-sectional study was conducted among 452 antenatal mothers attending health clinics in Klang in April 2018. Probability sampling was used and data was collected by using a validated self-administered questionnaire. The dependent variable of the study was short IPI and the independent variables were sociodemographic, obstetric history and planning of pregnancy. Analysis of data collected in the study was performed by using IBM Statistical Package for Social Science (SPSS) version 24.

    RESULTS: The prevalence of short IPI found in this study was 48%. Seven identified predictors of short IPI were: age less than 25 years old (Adjusted Odd Ratios; AOR 12.16, 95%CI: 4.72, 31.30), age of 26 to 30 years old (AOR 5.20, 95%CI: 2.62, 10.32), age of 31 to 35 years old (AOR 2.90, 95% CI: 1.50, 5.64), higher education (AOR 2.11, 95% CI: 1.34, 3.34), parity more than three (AOR 3.12, 95% CI: 1.42, 6.84), irregular menstruation (AOR 2.17, 95% CI: 1.40, 3.37) and unintended pregnancy (AOR 2.88, 95% CI: 1.88, 4.40).

    CONCLUSION: Innovative programmes, for example by making IPI information available through online resources, could effectively target young mothers as the younger generation prefers quick, easily-accessible and reliable information.

    Recent research has shown that children born before and after short birth intervals run a considerably greater risk of dying in infancy or childhood than do others. This report investigates which women have short interbirth intervals, under what circumstances, and for what reasons. The analysis uses data from the Malaysian Family Life Survey to examine influences on the two main behaviors--breastfeeding and contraceptive use--that affect birth interval length, and assesses the the impact of these same variables on the probability of having a birth interval of less than 15 months. The analysis shows that many of the independent variables affect breastfeeding and contraceptive use in opposite directions, with no significant net effect on the likelihood of a short interval. For example, a woman's education is negatively related to the probability that she breastfeeds, positively related to the probability that she uses contraceptives, and has no significant effect on the likelihood that the interpregnancy interval is less than 15 months. Having a family planning clinic nearby is associated with less breastfeeding, offsetting whatever positive effects family planning clinics have on contraceptive use in terms of the percentage of birth intervals that are so short as to be detrimental to infant and child health. Hence, factors that increase contraceptive use do not necessarily reduce the incidence of short interbirth intervals, because they are also associated with reduced breastfeeding. We simulate the proportion of intervals that would be short for alternative combinations of breastfeeding and contraceptive use in the population and show that over the period covered by the data (1961-75), breastfeeding had a considerably greater effect on preventing short interbirth intervals than did contraceptive use.

    Child mortality may affect spacing through biological and behavioral channels. The death of a child may elicit a desire to have another one soon; further, it may interrupt breastfeeding and shorten the sterile period following childbirth. The hypothesis that the child mortality-spacing linkage varies across parities, being strongest in the middle parities, is examined using microdata from Malaysia and the Cox-regression technique. The empirical results lend support to the hypothesis.

    PIP: Data from 297 interviews among married patients attending prenatal clinics in Malaysia in 1993 are used to determine the number, spacing, and timing of pregnancies. Only live born children are included. Findings indicate that 92.2% of women were 18-35 years old, 4.2% were under 18 years of age, and 3.6% were over 35 years old. 86.2% had 4 or fewer children and 13.8% had 4 or more children. 69.7% spaced children 2 or more years apart and 30.3% had birth spacing of under 2 years. Over 90% of women had their pregnancies during the ages of 18 and 35 years.

    Background and Objectives: Unmet need for contraception is the gap between women's reproductive intentions and their contraceptive behavior. This community based interventional study was carried out to determine the unmet needs for contraception, the reasons for this and to assess the impact of interventional measures on acceptance of contraception.
    Subjects and Methods: This study was conducted in 52 villages in the state of Maharashtra, India, among 363 married women selected by cluster sampling. Data was collected using an interview guide. An intervention was done for the women who had an unmet need and an assessment of the change was done subsequently. Data was analyzed by using SPSS.
    Results The prevalence of contraceptive usage was 59.2% and the prevalence of unmet need for contraception was 44% (160). The unmet need for spacing births was 53.8%, 38.7% for limiting births and 7.5% women were dissatisfied with the current contraceptive method. The reasons ranged from side effects to contraceptives to source of obtaining contraceptives. Age of the respondents, education and number of living children showed statistically significant association with unmet needs. Post intervention, the contraceptive prevalence rate increased significantly 85.7% and there was a significant reduction in the unmet needs for spacing and limiting births, equally there was a significant reduction of dissatisfaction with using contraception.
    Conclusion: Improvement in the use of contraception and addressing the unmet need for contraception requires community involvement and ongoing, sustained efforts by health workers to ensure quality care to the beneficiaries.

    "This paper presents a critical evaluation of three widely used tests for sex preferences: sex ratio, parity progression ratio and ordinary least squares [OLS] regression of birth interval. We show that under some appropriate conditions, the sex ratio is a valid test for sex preferences. The methods of parity progression ratio and OLS regression of birth interval fail to deal with right censoring and time varying covariates, which reduce the power of the tests. We suggest the use of hazard estimation to test for sex preferences. We demonstrate the differences among the tests by analyzing the retrospective fertility histories of the Chinese and the Malays in Malaysia. We find that unlike the two conventional methods, the hazard estimation gives clear and strong evidence of sex preferences among the Chinese in Malaysia."

    BACKGROUND: The number of child deaths is a potential indicator to assess the health condition of a country, and represents a major health challenge in Bangladesh. Although the country has performed exceptionally well in decreasing the mortality rate among children under five over the last few decades, mortality still remains relatively high. The main objective of this study is to identify the prevalence and determinants of the risk factors of child mortality in Bangladesh.

    METHODS: The data were based on a cross-sectional study collected from the Bangladesh Demographic and Health Survey (BDHS), 2011. The women participants numbered 16,025 from seven divisions of Bangladesh - Rajshahi, Dhaka, Chittagong, Barisal, Khulna, Rangpur and Sylhet. The 𝟀2 test and logistic regression model were applied to determine the prevalence and factors associated with child deaths in Bangladesh.

    RESULTS: In 2011, the prevalence of child deaths in Bangladesh for boys and girls was 13.0% and 11.6%, respectively. The results showed that birth interval and birth order were the most important factors associated with child death risks; mothers' education and socioeconomic status were also significant (males and females). The results also indicated that a higher birth order (7 & more) of child (OR=21.421 & 95%CI=16.879-27.186) with a short birth interval ≤ 2 years was more risky for child mortality, and lower birth order with longer birth interval >2 were significantly associated with child deaths. Other risk factors that affected child deaths in Bangladesh included young mothers of less than 25 years (mothers' median age (26-36 years): OR=0.670, 95%CI=0.551-0.815), women without education compared to those with secondary and higher education (OR =0 .711 & .628, 95%CI=0.606-0.833 & 0.437-0.903), mothers who perceived their child body size to be larger than average and small size (OR= 1.525 & 1.068, 95%CI=1.221-1.905 & 0.913-1.249), and mothers who delivered their child by non-caesarean (OR= 1.687, 95%CI=1.253-2.272).

    CONCLUSION: Community-based educational programs or awareness programs are required to reduce the child death in Bangladesh, especially for younger women should be increase the birth interval and decrease the birth order. The government should apply the strategies to enhance the socioeconomic conditions, especially in rural areas, increase the awareness program through media and expand schooling, particularly for girls.

    Background: Men's involvement in pre-pregnancy care is important to ensure a positive pregnancy outcome. The objective of this study is to determine the level of knowledge of pre-pregnancy care among men and the factors associated with poor knowledge.

    Methods: This work is a cross-sectional study conducted at the outpatient clinics of Hospital Universiti Sains Malaysia involving 235 married men. A self-administered questionnaire was used and it consisted of four sections: socio-demographic data, reproductive characteristics of couples, clinical characteristics and knowledge of pre-pregnancy care.

    Results: More than half of the men (51.9%) had poor knowledge of pre-pregnancy care, mostly on high-risk pregnancy, consequences of poor birth spacing and effect of maternal anaemia on a baby. The mean (SD) knowledge was 11.86 (3.85). Poor knowledge of pre-pregnancy care was significantly associated with age (adjusted odds ratio [AOR] = 0.96; 95% CI: 0.94, 0.99, P = 0.002) and education level (AOR = 2.61; 95% CI: 1.49, 4.57; P = 0.001).

    Conclusion: The men in our study had poor knowledge of pre-pregnancy care. Further health promotion and education are needed to be focused on men to increase their knowledge and share the responsibilities in maternal health.

    PIP: Contraceptive prevalence was determined in the Kelantan region of Malaysia, an area with relatively poor health indices. 350 women attending health clinics on rubber and palm-oil estates and living in surrounding suburbs were surveyed by clinic workers or during home visits. The sample included 273 Malays, 64 Indians and 13 Chinese. This area of Peninsular Malaysia is noted for the highest infant mortality rate (17.7), second highest crude birth rate (35.2) and highest dependency ratio (88%) in the country. 44.9% practiced contraception, highest in Chinese and lowest in Indians. Methods used were pills by (55%), traditional methods (19%), tubal ligation (18%), safe period (14%), injections (5.5%), IUD (4.7%), and condom (2.3%). The Malaysian traditional methods are herbal preparations from tree bark or roots, herb pills, and exercises after coitus. 34% of the non contraceptors had used contraception before but stopped because of side effects, religious or spousal objections, or desire to conceive. 74% had married in their teens. 46% of the non-contraceptors were spacing their children by prolonged breastfeeding.
