UNASSIGNED: Birth interval is the time period from live birth to a successive pregnancy or successive live birth which is the recommended to be at least 2 years or at least 33 months respectively. Both short and long birth intervals are associated with poor health outcomes for both mothers and babies. Therefore, the main objective of this study is to assess the length of birth intervals and its predictors among reproductive-age women in Dabat district.Methods: community-based cross-sectional survey conducted from December 10/2020 to January 10/2021. This study was done on 1262 multi para women. Five days training was given for the data collectors and supervisors. Bivariable and multivariable ordinal logistic regression analysis were done. Those variables which had P-value less than 0.25 in the bi variable analysis were entered to multivariable ordinal logistic regression analysis. An adjusted odds ratio with a 95% confidence interval and P-value less than 0.05 was used to determine significant determinants of birth interval.
UNASSIGNED: This study revealed that the magnitude of short and long birth interval was 30.59% and 22.82% respectively. Wealth status (poor: AOR = 0.72, CI: 0.53, 0.97), maternal education (Diploma and above: AOR = 2.79, CI: 1.18, 6.56), ANC follow up (having ante natal care: AOR = 2.15, CI: 1.72, 2.69), husband occupation (Employed: AOR = 1.77, CI: 1.03, 3.01) and history of abortion (abortion: AOR = 2.48, CI: 1.08, 5.66) were statistically significant factors.
UNASSIGNED: Higher percentage of mothers have either short or long birth interval. Birth interval is affected by socio demographic characteristics of mothers and husbands.

UNASSIGNED: sub-optimal birth spacing is higher in sub-Saharan countries including Ethiopia. It can affect the economic, political and social aspects of a given country. Therefore, this study aimed to assess magnitude of sub-optimal child spacing practice and associated factors among childbearing women in Southern Ethiopia.
UNASSIGNED: a community based cross-sectional study was conducted from July to September 2020. A random sampling technique applied to select kebeles, and systematic sampling was employed to recruit study participants. Data were collected by pretested and interviewer administered questionnaire through face-to-face interviews. Data cleaned and checked for completeness, and analyzed by SPSS version 23. A p-value of < 0.05 was considered as cutoff point to declare the strength of statistical association with 95% of CI.
UNASSIGNED: magnitude of sub-optimal child spacing practice was 61.7% (CI: 57.7: 66.2). Not attending formal education (AOR= 2.1 (95% CI: 1.3, 3.3), family planning utilization for less than 3 years (AOR= 4.0 (95% CI: 2.4,6.5), being poor (AOR= 2.0 (95% CI: 1.1, 4.0), breastfeeding of less than 24 months (AOR= 3.4 (95% CI: 1.6,6.0); having more than 6 children (AOR= 3.1 (95% CI: 1.4,6.7); and waiting time ≥30 minutes (AOR= 1.8 (95% CI: 1.2,5.9) were predictors of sub-optimal birth spacing practices.
UNASSIGNED: sub-optimal child spacing was relatively high among the women of Wolaita Sodo Zuria District. Improving utilization of family planning, expanding all inclusive adult education, delivering community based continuous education on optimum breast-feeding practice, involving women in income generating activities, and facilitated maternal services were recommended to fill the identified gap.

OBJECTIVE: A short birth interval is a universal public health problem resulting in adverse maternal, neonatal, and child outcomes. Therefore, the aim of this study was to identify determinants of short birth interval among ever married reproductive age mothers who live in Jigjiga city administration, Eastern Ethiopia, 2020.
METHODS: A community-based unmatched case-control study was used among 194 cases and 194 controls in Jigjiga city administration from September to December 2020. Cases were women with short birth interval (less than 3 years) and controls were women with optimum birth interval (3-5 years). Simple random sampling technique was employed to select cases and controls. Data were entered into Epi data version 4.2 and analysis with SPSS version 22. Binary logistic regression with 95% confidence interval at p < 0.05 is used to declare significantly associated predictors of short birth interval.
RESULTS: This study reported that women who have not attended formal education (adjusted odds ratio = 5.28, 95% confidence interval: (2.25-12.36)), attended primary education (adjusted odds ratio = 2.79, 95% confidence interval: (1.46-5.34)), women who married to a polygamous husband (adjusted odds ratio = 3.69, 95% confidence interval: (1.80-7.58)), having a history of neonatal death (adjusted odds ratio = 2.15, 95% confidence interval: (1.07-4.32)), preceding child being female (adjusted odds ratio = 3.69, 95% confidence interval: (2.02-6.72)), and never used contraceptive methods (adjusted odds ratio = 3.69, 95% confidence interval: (2.02-6.72)) were identified as determinants of the short birth interval.
CONCLUSIONS: Short birth intervals were associated with educational level of the women, sex of the baby, husband marriage types, history of neonatal death, and contraceptive utilization. Strategy should be engaged to enhance women education, contraceptive uses, and to decrease neonatal death.

UNASSIGNED: Total fertility rate (TFR) in Iran decreased from the year 2000 and recently Iran has experienced fertility rates below replacement level. Birth interval is one of the most important determinants of fertility levels and plays a vital role in population growth rate. Due to the importance of this subject, the aim of this study was analyzing three birth intervals using three Survival Recurrent Event (SRE) models.
UNASSIGNED: In a 2017 cross-sectional fertility survey in Tehran, 610 married women, age 15-49 years, were selected by multi-stage stratified random sampling and interviewed using a structured questionnaire. The effects of selected covariates on first, second and third birth intervals were fitted to the data using the Prentice-Williams- Peterson-Gap Time (PWP-GT) SRE model in SAS 9.4.
UNASSIGNED: Calendar-period had a significant effect on all three birth intervals (P<0.01). The Hazard Rate (HR) for a short birth interval for women in the most recent calendar-period (2007-2017) was lower than for the other calendarperiods. Women\'s migration influenced second (P=0.044) and third birth intervals (P=0.031). The HR for both birth intervals in migrant women was 1.298 and 1.404 times shorter, respectively than non-migrant women. Women\'s employment (P=0.008) and place of residence (P<0.05) also had significant effects on second birth interval; employed women and those living in developed, completely-developed and semi-developed areas, compared to unemployed women and those living in developing regions, had longer second birth intervals. Older age at marriage age increased the HR for a short third birth interval (P<0.01).
UNASSIGNED: The analysis of birth interval patterns using an appropriate statistical method provides important information for health policymakers. Based on the results of this study, younger women delayed their childbearing more than older women. Migrant women, unemployed women and women who live in developing regions gave birth to their second child sooner than non-migrant employed women, and women who lived in more developed regions. The implementation of policies which change the economic and social conditions of families could prevent increasing birth intervals and influence the fertility rate.

Interpregnancy interval (IPI) is associated with adverse perinatal outcomes, but its contribution to severe maternal morbidity (SMM) remains unclear. We examined the association between IPI and SMM, using data linked across sequential pregnancies to women in California during 1997-2012. Adjusting for confounders measured in the index pregnancy (i.e., the first in a pair of consecutive pregnancies), we estimated adjusted risk ratios for SMM related to the subsequent pregnancy. We further conducted within-mother comparisons and analyses stratified by parity and maternal age at the index pregnancy. Compared with an IPI of 18-23 months, an IPI of <6 months had the same risk for SMM in between-mother comparisons (adjusted risk ratio (aRR) = 0.96, 95% confidence interval (CI): 0.91, 1.02) but lower risk in within-mother comparisons (aRR = 0.76, 95% CI: 0.67, 0.86). IPIs of 24-59 months and ≥60 months were associated with increased risk of SMM in both between-mother (aRR = 1.18 (95% CI: 1.13, 1.23) and aRR = 1.76 (95% CI: 1.68, 1.85), respectively) and within-mother (aRR = 1.22 (95% CI: 1.11, 1.34) and aRR = 1.88 (95% CI: 1.66, 2.13), respectively) comparisons. The association between IPI and SMM did not vary substantially by maternal age or parity. In this study, longer IPI was associated with increased risk of SMM, which may be partly attributed to interpregnancy health.

After China\'s One-child Policy was replaced with the Two-child Policy in 2013, the rate of second pregnancies with a longer inter-pregnancy interval (IPI) has suddenly increased in that country; however, the effect of long IPIs (≥49 months) on perinatal outcomes remains unreported.
This was a retrospective cohort study in China from July 2015 through June 2016. We used univariate and multivariate logistic regression models to test the associations among IPI, maternal age, and perinatal outcome (preterm delivery, term low birthweight, and small-for-gestational age). We included baseline factors and variables with biological plausibility as confounders.
Our analytic sample included 3309 second pregnancies. The mean IPI was 75.36 months. Compared with second pregnancies with a short IPI of 7-24 months, those with long IPIs had higher adjusted odds ratios (ORs) of preterm delivery (1.70-2.00 [95% CI 1.20-3.33]) and term low birthweight (2.16-2.68 [1.10-6.17]), but not small-for-gestational age. The mean maternal age at current delivery was 32.0 years. Compared with the reference group (25-29 years), second pregnancies for the oldest maternal age group (≥35 years) showed no statistically significant increased ORs for adverse perinatal outcomes.
Long IPI is a significant contributor to preterm delivery and term low birthweight. Health care providers need to pay close attention to preterm delivery prevention and fetal growth during prenatal care for second pregnancies where the mothers have long IPIs.

BACKGROUND: Optimal birth spacing has health advantages for both mother and child. In developing countries, shorter birth intervals are common and associated with social, cultural, and economic factors, as well as a lack of family planning. This study investigated the first birth interval after marriage and preceding interbirth interval in Nepal.
METHODS: A community-based prospective cohort study was conducted in the Kaski district of Nepal. Information on birth spacing, demographic, and obstetric characteristics was obtained from 701 pregnant women using a structured questionnaire. Logistic regression analyses were performed to ascertain factors associated with short birth spacing.
RESULTS: About 39% of primiparous women gave their first child birth within 1 year of marriage and 23% of multiparous women had short preceding interbirth intervals (<24 months). The average birth spacing among the multiparous group was 44.9 (SD 21.8) months. Overall, short birth spacing appeared to be inversely associated with advancing maternal age. For the multiparous group, Janajati and lower caste women, and those whose newborn was female, were more likely to have short birth spacing.
CONCLUSIONS: The preceding interbirth interval was relatively long in the Kaski district of Nepal and tended to be associated with maternal age, caste, and sex of newborn infant. Optimal birth spacing programs should target Janajati and lower caste women, along with promotion of gender equality in society.

BACKGROUND: The extent of acceptance of contraceptive methods still varies within societies. Reliance on sterilisation is appearing earlier in marriage and among ever-younger ages and lower parities.
OBJECTIVE: To study the family planning practices adopted by women who undergo tubectomy before the acceptance of tubectomy.
METHODS: Cross-sectional study of tubectomy acceptors who attended a corporation referral maternity home in Bangalore, India by interview method using a pre-designed a pre-tested structured questionnaire.
RESULTS: Majority 295(73.9%) of the study subjects had not practised any method of contraception before they underwent sterilisation. Increase in the education levels of the study subjects was associated with an increase in the contraceptive use (temporary methods) before they accepted tubectomy; this association was found to be statistically significant (p<0.0001).

BACKGROUND: Despite her apparent economic success, India is plagued by a high burden of under-nutrition among children under five. This study was aimed at understanding some of the risk factors for under-nutrition in a region with favourable maternal and child health indicators.
METHODS: A case control study was carried out among children aged one to five years attending the paediatric outpatient department in six rural health care centres in Udupi taluk of Karnataka in Southern India. A total of 162 children were included in the study, of which 56 were cases. A semi-structured questionnaire was used to interview the caregivers of the children and the nutritional status was graded according to the Indian Academy of Paediatrics (IAP) grading of protein-energy malnutrition.
RESULTS: Under-nutrition was associated with illness in the last one month [OR- 4.78 (CI: 1.83 -12.45)], feeding diluted milk [OR-14.26 (CI: 4.65 - 43.68)] and having more than two children with a birth interval ≤2 years [OR- 4.93 (CI: 1.78 - 13.61)]. Lack of exclusive breast feeding, level of education of the caregiver and environmental factors like source of water did not have an association.
CONCLUSIONS: Childhood illness, short birth interval and consumption of diluted milk were some of the significant contributory factors noted among this population. Information, Education, Communication (IEC) campaigns alleviating food fads and promoting birth spacing is needed.
