The Fasting II Study
DiabetesMetabolic DiseasesThis study will determine whether an intensive fasting protocol alters hemoglobin A1c measurements or other markers of metabolic and cardiovascular risk by performing a 5-week clinical trial of fasting among 12 pre-diabetic individuals or diabetics whose disease is controlled by diet. Participants will undergo a 5-week intervention of once-per-week 24-hour water-only fasting, including at baseline and at the end of the week for each week of the study (a total of 6 24-hour fasts).

Diet, Physical Activity and Breastfeeding Intervention on Maternal Nutrition, Offspring Growth and...
ObesityWeight Gain3 moreNCDs are observed mostly in adults, however there is strong evidence that suggests NCDs origin early in life, thus the first 1000 days of life (conception to age 2yrs). Studies show that maternal BMI before conception and during pregnancy predict future risk of obesity and associated metabolic conditions in both mother and offspring. Weight gain during the first two years of life is also critical in defining the infant's predisposition to obesity during adulthood. Objective: to assess the effectiveness of delivering a primary health care intervention to enhance compliance with updated nutrition and health care (diet, physical activity and breastfeeding) standards from early pregnancy through the first year of life. Methods: cluster randomized controlled trial (CRCT), designed as a public health intervention "program effectiveness" study (i.e. intervention will be available through the established national health system under standard operating conditions). A cluster unit will be a primary health care centers (PHCC) in South-East Santiago 12 PHCC will be randomly allocated to: enhanced nutrition and health care (intervention group) or routine nutrition and health care (control group).We will recruit 200 women in each of 12 PHCC; assuming a 20% loss to f-up we will complete 960 women per arm. After randomization, pregnant women in the intervention PHCCs starting at their first pre-natal visit (< 15 wks.) will receive, diet and physical activity (PA) counseling-support based on updated recommendations and monitoring goals for weight gain & glycemic control and breastfeeding (BF) promotion till 12 m postpartum. Pregnant women who attend control PHCCs will receive routine antenatal care according to national guidelines. Expected results: participants in the intervention PHCCs will benefit by achieving adequate nutritional status & metabolic control, during and early after, pregnancy as well as adequate infant growth & development as a result of improved nutrition and health care practices. The results will likely be generalizable through the primary health care system; considering this is a "program effectiveness" trial conducted under "real life" conditions . Additionally, we will include specific ancillary mechanistic projects to better characterize the intervention and its impact.

Evaluating for Type-2 Diabetes in the Very Early Postpartum Period
DiabetesGestational3 morePregnancy-associated diabetes, known as gestational diabetes mellitus (GDM), is associated with an increased lifetime risk of developing diabetes mellitus (DM) or pre-diabetes. Up to 30% of women with GDM will continue have abnormal blood glucose tests 6 or more weeks after delivery. Early diagnosis and treatment of continued impaired glucose metabolism or DM is essential because serious health problems can result. Current guidelines recommend a 75-gram, 2-hour glucose tolerance test (GTT) 6 or more weeks after delivery for women diagnosed with GDM in order to identify those with continued DM or impaired glucose metabolism. However, approximately half of these women do not get glucose testing after delivery. The ability to test women while they are still hospitalized after having a baby could greatly increase diagnosis, care and treatment of women with abnormal glucose metabolism. Our objective is to determine if a 75-gram, 2-hour GTT administered to women with GDM two to four days after delivery can identify those who will have an abnormal GTT at 6-12 weeks after delivery.

Vitamin K to Slow Progression of Dyslipidemia and Diabetes Risk (Vita-K 'n' Kids Study II)
ObesityInsulin Resistance5 moreAnimal studies have found that vitamin K-dependent proteins matrix Gla protein and osteocalcin beneficially influence lipid and glucose metabolism, respectively. However, this concept has not been tested in humans at risk for dyslipidemia and diabetes risk. Vitamin K supplementation presents an opportunity to test the hypothesized link between the vitamin K-dependent proteins and markers of lipid and glucose metabolism. The investigators will conduct an 8-week vitamin K intervention (to manipulate carboxylation of matrix Gla protein and osteocalcin) and determine its effects on markers of dyslipidemia and diabetes risk. Sixty obese children will be randomly allocated to either the control group receiving placebo or the low-dose (45 mcg/d) or high-dose group (90 mcg/d) receiving vitamin K (menaquinone-7).

The Effect of Exercise Intervention on the Community's Older Adults
Metabolic DiseaseOsteoporosis is a serious global health problem, second only to cardiovascular disease. Osteoporosis is the most common metabolic bone disease in the elderly population, characterized by loss of bone mineral density (BMD) and continuous destruction of bone microstructure, especially in postmenopausal women. It gives rise to bone fragility and fracture risk. Moreover, as people grow older, falls frequently occur with high severity, and nearly 35% to 45% of persons aged 65 or older fall at least once a year. Osteoporotic fractures increase mortality, morbidity, chronic pain, and the cost of social care and it decreases the quality of life. Here, investigators plan to perform different exercise interventions such as circuit exercise, aerobic dance and Tai Chi on the community's older adults to evaluate whether exercise intervention could improve the bone mineral density, physical fitness, muscle strength or quality of life.
