73 malnutritive children and 146 under 5 year old children with well nutritional status in Tan Lap commune, Dan Phuong district, Ha Tay province were studied. The children in the 2 months food - deficit per year household got 3 fold higher risk of malnutrition in comparing with children of good nutrition. Lack of communication media, televisionset and household with more than 2 children were indirect risks influencing on the nutrition and the care (with OR>3). Children born with low body weight had 8.8 fold higher risk of malnutrition than normally born children (OR = 6,8). Lack or late breasfeeding was a high risk of malnutrition.

The hygiene at 15 food factories in Hanoi and 10 food factories in HCM city was surveyed. Results showed that many factories couldn’t assume responsibility for basic requirements of food safety, a third of factories were evaluated bad hygiene. Most half of workers didn’t ensure personal hygiene when working. Food factories brought bad effects about smell, chemical odor and sewage

Objective: The purpose of this study was to identify factors associated with twin pregnancy following day 3 double embryo transfer (DET). Methods: This retrospective cohort study incorporated data from 16,972 day 3 DET cycles. The participants were women aged between 18 and 45 years who underwent in vitro fertilization with intracytoplasmic sperm injection (IVF/ICSI) at My Duc Assisted Reproduction Technique Unit (IVFMD), My Duc Hospital, located in Ho Chi Minh City, Vietnam. Results: Of the 16,972 day 3 DET cycles investigated, 8,812 (51.9%) resulted in pregnancy. Of these, 6,108 cycles led to clinical pregnancy, with 1,543 (25.3% of clinical pregnancies) being twin pregnancies. Factors associated with twin pregnancy included age under 35 years (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.32 to 1.71; p<0.001) and cycles involving the transfer of at least one grade I embryo. Relative to the transfer of two grade III embryos, the risk of twin pregnancy was significantly elevated following the transfer of two grade I embryos (OR, 1.40; 95% CI, 1.16 to 1.69; p<0.001) or a combination of one grade I and one grade II embryo (OR, 1.27; 95% CI, 1.05 to 1.55; p=0.001). Conclusion By analyzing a large number of IVF/ICSI cycles, we identified several predictors of twin pregnancy. These findings can assist medical professionals in tailoring treatment strategies for couples with infertility.
