Lower albumin levels are associated with frailty measures, trace elements, and an inflammation marker in a cross-sectional study in Tanushimaru.

Background: There is little data on the association between the lower nutrition represented by serum albumin levels and related factors in a general population. The present study aimed to determine whether the albumin level positioned as some kind of biomarker with frailty measures, trace elements, and an inflammation marker.

Methods: In 2018, we performed an epidemiological survey in 1368 subjects who resided in Tanushimaru, Japan, in which we examined the blood chemistry including albumin, trace elements, hormone levels, and carotid ultrasonography.

Serum Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) is Independently Associated with Insulin Resistance, Triglycerides, Lipoprotein(a) Levels but not Low-Density Lipoprotein Cholesterol Levels in a General Population.

Aim: Proprotein convertase subtilisin/kexin type 9 (PCSK9) has been identified as an important regulator of low-density lipoprotein (LDL) receptor processing. Evolocumab and alirocumab are PCSK9 inhibitors; however, little is known about the association between PCSK9 levels and lipid profiles in a general population. Because PCSK9 inhibitors have LDL-C lowering effects, we investigated whether there is a positive correlation between serum PCSK9 levels and LDL-C or lipoprotein(a) [Lp(a)].

Association between growth hormone and hypertension in a general population.

Insulin-like growth factors are polypeptides, with arrays similar to insulin, and insulin-like growth factor 1 (IGF-1) is secreted via stimulation by growth hormone (GH) in the liver. The lack of both GH and IGF-1 leads to physiological age-related changes in the cardiovascular system; however, the role of IGF-1 and GH in hypertension has not been fully elucidated. Thus, we examined the association between plasma IGF-1 and GH levels and hypertension.

Trends in nutritional intake and coronary risk factors over 60 years among Japanese men in Tanushimaru.

We investigated the relationship between time trends in nutrient intake and coronary risk factors/mortality rates in Tanushimaru, a Japanese cohort of the Seven Countries Study. All men between the ages of 40 and 64 were enrolled. Subjects numbered 628 in 1958, 539 in 1977, 602 in 1982, 752 in 1989, 402 in 1999, 329 in 2009, and 160 in 2018.

Habitual coffee intake reduces all-cause mortality by decreasing heart rate.

It is well known that subjects with metabolic syndrome show an elevated resting heart rate. We previously reported that elevated heart rate was significantly related to all-cause mortality, and that coffee consumption was inversely associated with metabolic syndrome. We hypothesized that higher coffee consumption may decrease all-cause mortality by reducing resting heart rate.

Association between physical activity, occupational sitting time and mortality in a general population: An 18-year prospective survey in Tanushimaru, Japan.

Aims: It is well known that a decline in physical activity is associated with an increase of all-cause death including cardiovascular events and cancer. Few studies have examined the association between occupational sitting time and mortality. Therefore, we investigated this issue in a general population.
