Background: Mortality rate in low-birth-weight infants is almost 30 times more than that in those with normal weight, so the birth of low-birth-weight infants is one of the most serious health problems in the world. Therefore, this nested case-control study was conducted to investigate the risk factors associated with low birth weight among infants in the rural population of Kerman province. Methods: This nested case-control study was performed in rural areas of Kerman province, southeastern Iran. Case (n = 155) and control (n = 310) groups were selected using risk set sampling. Data were analyzed through Point and distance estimation (OR, CI) using conditional logistic regression method by Stata-12 software. Results: The results of multivariate analysis showed that maternal BMI [OR = 0.3, CI 95% (0.1, 0.9)], gestational age [OR = 3.8, CI 95% (0.9, 6.1)], history of stillbirth [OR = 4.8, CI 95% (1.3, 11)], history of pregnancy bleeding [OR = 3.7, CI 95% (0.7, 9)], pregnancy craving [OR = 3, CI 95% (1.1, 3.8)], and the level of health workers' care [OR = 0.4, CI 95% (0.1, 0.9)] are the risk factors affecting LBW in infants (P < 0.05). Conclusions: Low birth weight is a multifactorial phenomenon. Therefore, raising public awareness, providing nutritional counseling to pregnant mothers, regular referral to health homes to receive health care, and identifying risk factors and referral to higher level specialists and health centers can be effective in reducing the risk of birth of LBW infants.

Background: Calorie restriction (CR) is known as a nutritional gold standard for life extension and different studies have shown that insulin-like growth factor (IGF1) reduction through CR may be involved in CR's anti-aging effects. Besides, time-restricted-feeding (TRF) is also highlighted due to more feasibility and positive health effects. We designed this study to compare the effects of CR and TRF on IGF1 and other metabolic parameters. Methods: Fifty-two male Wistar rats (3 weeks old) were subjected to either a control (CON, n = 11) diet or high-fat diet (HFD, n = 42) for 17 weeks. In the second phase of the study, the HFD group were divided into four groups (n = 9) 1) 30% CR, 2) Night Intermittent Fasting (NIF, active phase), 3) day intermittent fasting (DIF, rest phase), and 4) Ad-Libitum (AL) with a standard diet for 10 weeks. Blood samples were collected at the end of both phases. Results: HFD increased IGF1 and deteriorated lipid profiles, except for triglycerides (P: 0.018, 0.008.0.012, 0.032) but CR in these obese subjects could not lower the IGF1 level. HDL significantly decreased in DIF compared to CON and CR (P; 0.001). Meanwhile, HOMA-IR increased in DIF and was significant compared to CR (P: 0.002). Serum glucose levels decreased in CR compared to all groups except for CON (P: 0.001). Conclusion: Data indicates the role of previous obesity on the effect of CR on the IGF1 level and highlights the effect of inappropriate time of food intake on HDL and APOA1.
