Iron deficiency and folic acid anemia cause decrease in ferritin and folic acid levels that can interfere with the intake of oxygen and nutrients to the fetus resulting in LBW and reduced brain growth during pregnancy. The aim of the study was to determine the relationship between ferritin and folic acid levels in pregnant women with newborn weight and head circumference.This study was a cross sectional study conducted on 55 pregnant women at 37-42 weeks who were taken by consecutive sampling technique. The study was carried out in the Working Area of the Puskesmas and the Regional Health Laboratory of the Merangin Regency, and the health laboratory of West Sumatra Province from May 25 to July 13, 2018. Test the normality with the Kolmogorov-smirnov test and the correlation test using Pearson and Spearman.The results showed ferritin mean 23,643±16,682 ng/ml, folic acid 14,093±4,578 ng/ml, newborn weight 3047,27±399,005 gram and head circumference 33,02±1,163 cm. Statistical test results showed no correlation between ferritin levels with body weight (r=0.063, p=0.648) and head circumference (r=0.018, p=0.895) and folic acid levels with body weight (r=-0.036, p=0.795) and head circumference (r=-0.098, p=0.477).The conclusions of the study were that ferritin and folic acid levels of pregnant women had no significant correlation with newborn weight and head circumference. By improving nutrition, socioeconomic, qualitative antenatal care, initial referral of risky cases and supplementation of iron and folic acid can reduce the incidence of anemia.

Abstract Objective: To clarify nutrient supplementation usage and primary source of information among pregnant women in China. Design: This cross-sectional study used information on nutrient supplementation and primary source of information collected via face-to-face interviews. Data on the usage of folic acid, calcium/vitamin D, iron, vitamins, docosahexaenoic acid, and other dietary supplements were collected. Primary source of information were categorized as family/relatives, friends/co-workers, the Internet, books/magazines, television/radio, doctors, other people, and oneself. Setting: Maternal and Child Health Hospital in Chengdu, China. Participants: 1081 Chinese pregnant women aged ≥ 20 years with singleton pregnancies. Results: In all three trimesters of pregnancy, usage was highest and most stable for folic acid (81.7%), followed by vitamins (vitamin A, B-group vitamins, vitamin C, and multivitamins; 75.0%), whereas calcium/vitamin D (51.4%) and iron (18.1%) usage was low, potentially indicating a deficiency risk. All supplementation usage percentages increased with pregnancy duration (p < 0.05). Notably, approximately 10% of the pregnant women in our study did not use any nutrient supplementation, and this was especially common in early pregnancy. More than 50% of the women reported getting information on nutrient supplementation from family members, and about 30% reported getting this information from doctors. Conclusions: Among pregnant women in China, awareness about nutrient supplementation increases as the pregnancy progresses, but some types of nutrient supplementation (such as calcium/vitamin D and iron) remain at low levels. It is necessary to pay more attention to the health education of pregnant women in China, and the influence of family members should be emphasized.

Abstract Background: Although the internet can be a source of reassurance and clarification for expectant women, it ‎could cause concerns or feelings of worry when reading about pregnancy-related ‎information. The current research sought to assess the feelings of worry and perceived reliability towards online pregnancy-related information and the associated factors among expectant women attending antenatal clinics at primary healthcare centers in Qatar.Methods: A cross-sectional study design was employed. The participants were recruited through a systematic random sampling technique. ‎A self-administered questionnaire was used to collect data from the participants. Descriptive and analytic statistics were used when appropriate‎.Results: A total of 327 expecting women completed the questionnaire. Most participants were aged between 26-34 years (74.1%), held a college/university degree (76.4%), and multigravidas (73.1%). About one-third of the women ‎(31.2‎%) reported feeling worried due to something they read online. The participants coped with these feelings by consulting their antenatal care provider at the next appointment (51.0%) or by talking with relatives and friends (47.0%). Furthermore, most women (79.2%) considered online pregnancy-related information to be reliable or highly reliable. Holding a college/university degree, primigravidae, and having no children were factors significantly associated with a high perception of reliability of online health information.Conclusion: Although online pregnancy information caused feelings of worry for some pregnant ‎women, most women perceived such information to be reliable. Thus, antenatal care providers should be equipped to guide pregnant women on how to access high-quality web-based information.

Antenatal care or antenatal care is a planned program that is observation, education and medical treatment for pregnant women, to obtain a safe and satisfying pregnancy and childbirth process. The indicator used to assess the access of pregnant women to antenatal care is K1 direction (first visit) is the contact of pregnant women to health workers and K4 (perspective visit) is 4 or more times contact with health workers. From the data of the Padang City Health Office, it was found that the Air Tawar Puskesmas with this low level was caused by various factors. The purpose of this study was to determine factors related to the use of antenatal services. This type of research is a quantitative study with cross sectional study design with 110 respondents of third trimester pregnant women with purposive sampling technique. Data analysis was performed univariate, bivariate with Chi squre test. From the research results obtained from the five factors studied, it was found that the factors related to the use of antenatal services in freshwater health centers were access or distance with pvalue 0.009 = OR 21.676), service availability factors with a p value of 0.001 = OR 9.293, the role factor midwives with a p value of 0.001 = OR 12.302, while the family income factor, disease complaints obtained results have nothing to do with the use of antenatal services. The author's suggestion is that there is a need for good coordination with the Independent Practice Midwife (BPM), revitalize puskesmas to more strategic places and improve better facilities, improve accessibility that can be minimized, strive to reach pregnant women, especially for accessibility that is less affordable.

Abstract Background: Nearly all of maternal deaths in the world occurred in sub-Saharan African countries. As Ethiopian demographic health survey report, there were 412 maternal deaths per 100,000 live births in 2016. Delays in decision to seek and receive care are the main causes of these deaths. Birth preparedness and complication readiness plan has been globally endorsed pivotal strategy to decrease these delays. Therefore, this study was aimed to assess the level of practice and factors associated with practice of birth preparedness plan among pregnant women. Methods: Community based cross-sectional study was done among 356 pregnant women selected by simple random sampling technique from July 1-30/2017 in Debretabor town. We selected samples by simple random sampling technique. Data were collected using interview administered questionnaire. Then, we coded, cleaned and entered data through Epidata version 3.1. Finally, exported and analyzed by SPSS. Logistic regression analysis was done to identify association between explanatory variables and practice of birth preparedness and complication plan. An adjusted odds ratio with 95% confidence interval and p-value less than 0.05 was computed to determine the level of significance in multi-variable logistic regression model.Results: Prevalence of birth preparedness and complication readiness plan was 73.9% in this study. primary education status (AOR=3.2,95%CI,1.3-7.8) and secondary educational status (AOR=4.1,95%CI,1.6-10.3), Primigravida (AOR=4.7,95%CI,1.9-11.3), partner involvement in birth preparedness and complication readiness plan (AOR=3.4,95%CI,1.9-6.1), initiating antenatal care in first trimester and media exposure (AOR=1.9,95%CI,1.0-3.3) were significantly associated factors with birth preparedness and complication readiness plan in this study. Conclusions: Level of practice of birth preparedness and complication readiness plan was high in the current study. Higher education status, early ante-natal care initiation, partner involvement in birth preparedness and exposure to media were the factors associated with practice of birth preparedness and complication readiness. Therefore, emphasize on continues education through media, design educational curriculum which should include birth preparedness plan, increase partner participation in birth preparedness and complication readiness plan. Furthermore, early initiation of antenatal care is mandatory.

Abstract: MMN, Newborn Baby Weight. During pregnancy food is required with good quality and quantity to meet the nutritional needs of mother and baby. The low nutritional status of pregnant women during pregnancy can lead to various adverse effects for mothers and infants, such as those born with Low Birth Weight (LBW). LBW babies have a 10 to 20 times greater chance of dying than babies born with enough birth weight. Multiple Micro Nutrient (MMN) contains 15 types of vitamins and minerals most important for pregnant women, including vitamin A, vitamin E, vitamin D, vitamin B1, vitamin B2, niacin, Vitamin B6, vitamin B12, folic acid, vitamin C, Fe , folic acid, Zink, Copper, Selenium, and Iodine. MMN is one of the nutrients to prevent the occurrence of anemia because in MMN there are factors forming Hemoglobin ie Fe, Vitamin B12 and folic acid. The availability of adequate hemoglobin makes the metabolic system work well. Lack of hemoglobin not only affects the health of the mother but also affects the health of the fetus it contains, including the growth of the fetal inhibition (such as weight, body length). The purpose of this study was to prove the effect of MMN on newborn weight in Pandes Klaten village. This type of research is arestrospective study with cross sectional design. The subjects of this study were BBL (newborn) whose mother consumed MMN during pregnancy. Different test sing Independent T-test to compare control group and treatment group. Significant value in this study was p <0.05. The results of this study were no significant difference between birth weight between control group and MMN treatment group (P = 0.879). In conclusion MMN has no significant effect on newborn weight gain.

Latar belakang: Angka Kematian Ibu (AKI) merupakan salah satu indikator pembangunan kesehatan di Indonesia. Upaya percepatan penurunan AKI dapat dilakukan dengan menjamin agar setiap ibu mampu mengakses pelayanan kesehatan ibu hamil yang berkualitas. Apabila antenatal care dimanfaatkan dengan baik maka kesehatan ibu dapat terpantau secara berkesinambungan dari masa kehamilan sampai dengan persalinan. Metode: Desain penelitian adalah kuantitatif dengan rancangan cross sectional study. Populasi pada penelitian ini adalah semua ibu yang memiliki bayi usia 0-11 bulan di Kabupaten Gowa sebanyak 122 orang. Sampel sebanyak 93 orang diambil dengan menggunakan teknik accidental sampling, besar sampel ditentukan dengan menggunakan rumus Slovin Hasil: Persepsi ibu hamil terhadap peran petugas kesehatan dalam pelayanan antenatal berdasarkan pengorbanan moneter tidak menunjukkan korelasi. Ibu hamil yang memiliki persepsi pengorbanan moneter kecil dan mengatakan peran petugas kesehatan kurang dalam pelayanan antenatal sebanyak 90,0%. Ibu hamil yang memiliki persepsi pengorbanan moneter sangat kecil dan mengatakan peran petugas kesehatan kurang sebanyak 83.1%. Sedangkan persepsi pengorbanan waktu menunjukkan adanya korelasi dengan peran petugas kesehatan dalam pelayanan antenatal. Ibu hamil yang memiliki persepsi pengorbanan waktu besar dan mengatakan peran petugas kesehatan kurang dalam pelayanan antenatal sebanyak 100%. Ibu hamil yang memiliki persepsi pengorbanan moneter besar dan mengatakan peran petugas kesehatan kurang dalam pelayanan antenatal sebanyak 90.2%. Kesimpulan: Persepsi ibu hamil terhadap peran petugas kesehatan dalam pelayanan antenatal berdasarkan pengorbanan moneter tidak menunjukkan korelasi sedangkan berdasarkan pengorbanan waktu menunjukkan ada korelasi. Perlu meningkatkan kecepatan proses pelayanan pemeriksaan kehamilan pada ibu hamil oleh tenaga kesehatan. Kata kunci: Pelayanan antenatal, Ibu Hamil, Pengorbanan, Waktu, Moneter   Abstract Background: Maternal Mortality Rate (MMR) is one indicator of health development in Indonesia. Efforts to accelerate the reduction of MMR can be done by ensuring that every mother is able to access quality maternal health services. If antenatal care is utilized properly, maternal health can be monitored continuously from pregnancy to delivery. Methods: The study design was quantitative with a cross sectional study design. The population in this study were all pregnant women who had a gestational age of 7 to 9 months in Gowa Regency as many as 122 people. A sample of 93 people was taken using accidental sampling technique, the sample size was determined using the Slovin formula. Results: Perception of pregnant women towards the role of health workers in antenatal care based on monetary sacrifice did not show a correlation. Pregnant women who have a perception of small monetary sacrifice and say the role of health workers is lacking in antenatal care are 90.0%. Pregnant women who have a perception of monetary sacrifice are very small and say the role of health workers is less as much as 83.1%. While the perception of sacrifice of time shows a correlation with the role of health workers in antenatal care. Pregnant women who have the perception of sacrifice of big time and say the role of health workers lacking in antenatal care as much as 100%. Pregnant women who have a perception of great monetary sacrifice and say the role of health workers is lacking in antenatal care are 90.2%. Conclusion: Perception of pregnant women towards the role of health workers in antenatal care based on monetary sacrifice does not show correlation while based on time sacrifice shows there is correlation. Need to increase the speed of the process of pregnancy examination services for pregnant women by health workers. Keywords: Antenatal care, Pregnant Women, Sacrifice, Time, Monetary

Background: The increased demand for iron and folic acid during pregnancy is not met through diet due to insufficiency or reduced bioavailability of nutrients among women from low income countries. Thus, iron and folic acid supplementation (IFAS) is a promising interventional strategy for control of anaemia during pregnancy. Kenya adopted the global IFAS intervention with a target of 80% coverage by 2017, however, the compliance remains low. Increasing awareness, counselling, communication and community education on IFAS have improved compliance among pregnant women. Thus, we aimed to determine: IFAS knowledge, availability, practices, and content of IFAS counselling among pregnant women attending health facilities in Kiambu County, Kenya. Methods: A cross-sectional study involving 364 pregnant women aged 15-49 years. A two stage cluster sampling, including one sub-county and five public health facilities were used. A pre-tested structured questionnaire consisting of socio-demographic data, maternal knowledge and counselling on IFAS was used. An observation checklist was used to observe practices and content of antenatal counselling session in each facility. Data was analysed using STATA in which descriptive and inferential statistics were computed. Results: Of 364 respondents, less than half (40.9%) scored high on knowledge on IFAS. Women who were counselled on duration of IFAS intake, side effects, and their mitigation were more likely (p <0.005) to have high IFAS knowledge. Although all the health facilities had varied IFAS posters displayed, none had key IFAS counselling documents. Conclusion: Less than half of the pregnant women had high IFAS knowledge, IFAS documents were scarce in health facilities, IFAS counselling information in different health facilities was limited and varied and content of counselling was associated with levels of knowledge on IFAS. This underscores the need to strengthen focused and targeted IFAS counselling for pregnant women and standardization of counselling messages to improve compliance and pregnancy outcomes.

Objective: Maternal nutrition is considered an important pillar in the pregnancy outcomes for both mother and infant. A mother’s malnutrition and inadequate nutrient intake is associated with many undesirable pregnancy outcomes. Hence, assessing the nutritional status of the mother in the early stages of the pregnancy and preventing any inadequacy can preclude many health problems for both mother and infant. Therefore, this study aimed to assess the adequacy of nutrient intakes among Jordanian pregnant women as compared to their corresponding dietary reference intakes (DRIs). Methods: This cross-sectional study was conducted at a major University Hospital in Jordan. Three hundred pregnant women were invited to participate in the study and 286 agreed to participate. Fifty pregnant women were enrolled at week 9, then 96 pregnant women were at week 20 and 137 pregnant women were at week 30 of pregnancy. The participants completed the interview-based demographic questionnaire, pregnancy physical activity questionnaire, and quantitative food frequency questionnaire (FFQ). Results: The mean energy intake was 2768.9 ± 767.8 kcal/day and it was significantly higher in the 3rd trimester (p < 0.05). Women in the 3rd trimester consumed significantly more protein, carbohydrates, and sugar than women in the 1st and 2nd trimesters (p < 0.05). The pregnant women in the 3rd trimester consumed more sodium than women in the 1st and 2nd trimesters (p < 0.05). The vitamin K intake was significantly (p = 0.045) lower in the 2nd trimester than the 1st and 3rd trimesters. The calcium intake was significantly higher in the 3rd trimester than the 1st and 2nd trimesters (p = 0.021). The total micronutrient (vitamins B1, B2, B3, B6, B12, and D, calcium, and iron) intakes derived from dietary supplements and food sources throughout the 3 trimesters was significantly higher in the 3rd trimester than the 1st and 2nd trimesters (p < 0.05). The vitamin D, calcium, and iron intakes had the most significant increases between the 1st and 3rd trimesters (p < 0.001), while folic acid intake was significantly higher in the 1st trimester than the 2nd and 3rd trimester (p < 0.001). Most women exceeded the tolerable upper intake level (UL) for sodium in all trimesters, while 82% of women exceeded the UL of folic acid in the 1st trimester and from the supplement, not the diet. Conclusion: While the intake of some nutrients from food alone remains below the DRIs in the diets of pregnant women, the intake of other nutrients is above the UL. Raising the awareness of pregnant women about their diet and how a supplement intake can reduce the risk of inadequate intake for many micronutrients and improve their pregnancy outcomes is of great importance.
