This study aimed to analyze factors affected fish consumption of Indonesian women. This research design was a cross-sectional referred to the Basic Health Research in 2010, conducted by the Health Institute for Research and Development The Ministry of Health Republic of Indonesia. Objects of this study were women within 19-55 years old. The variabel such as nutritional status, social economy and fish consumption were analysed using logistic regression method. The analysis showed that the consumption of fish protein accounted for 19.1 g/day or 82% of total animal protein intake in women subjected in this research, however thisconsumption only met 34% requirement of protein per day. The average of body mass index of the women was 23.2 ± 4.0 kg/m2 and was categorized as normal nutritional status. Positive relationship was found between fish consumption, intake of fat, and nutritional status. The consumption of fish was affected by marital status and economic status. Women with marital status had 1.13 times higher likelihood to consume fish than unmarried women. Economic status also determined fish consumption volume.

Abstract Molecular and behavioral timekeeping is regulated by the circadian system represented on the cellular level by clock transcription factors, including Period2 (PER2), Bmal1, Clock and Cry. These transcription factors drive a daily ~24h rhythm in gene expression leading to tissue specific receptor expression optimizing sensitivity to hormones and drugs dependent on the time of day. To synchronize circadian rhythms in the body to the time of day, the brain’s suprachiasmatic nucleus (SCN) translates environmental light information into neuronal and endocrine signals allowing circadian rhythm synchrony. Despite the critical role of circadian rhythms in fertility, it remains unknown how circadian rhythms change within reproductive tissues during pregnancy, and how these adaptations might impact drug efficacy. Monitoring wheel-running patterns in circadian PER2::luciferase (PER2::LUC) reporter mice, we confirmed that pregnancy is associated with reductions of activity and identified a correlation between delayed onset of behavioral activity during late pregnancy and ex vivo SCN PER2::LUC period, whereas no correlation between arcuate nucleus PER2::LUC rhythms was identified. The time of day of peak PER2::LUC expression provides a time-stamp as to the circadian phase of a tissue. Pregnancy impacted circadian synchrony in the reproductive axis, with the most dramatic change within the uterus. To understand how circadian rhythms responded to input during pregnancy, we performed a pharmacology study and found that circadian rhythm generation in the uterus responded differentially to hormones regulating pregnancy and labor depending on gestational age and the time of day of drug administration. To test for functional changes in uterine contraction capacity, we recorded ex vivo uterine contractions. Our preliminary data reveal a circadian change in uterine function in the mouse, which impacted labor regulating drug efficacy depending on the time of day. Together our data show that pregnancy is associated with behavioral changes in locomotor activity patterns, as well as adaptations in phase-relationships in reproductive tissues. Our chrono-pharmacology study indicates that a better understanding of labor-regulating drug efficacy can potentially allow increased efficacy of currently used drugs in the clinic to both induce labor as well as halt preterm labor.

AbstractThe purpose of this chapter is to describe the nutritional recommendations for older adults and change in requirements with age and disease. Key factors influencing nutritional requirements, dietary intake, and nutritional status in old adults will be described, including specific nuances for geriatric and orthogeriatric patients.
