Excessive drinking by college students is a major public health problem in Japan. However, data on heavy episodic drinking (HED) and nomihodai, a several-hour all-you-can-drink system, are scarce. We surveyed the drinking behavior of undergraduate and graduate students at 35 colleges, and examined the association between HED and use of nomihodai. The study used a cross-sectional design conducted by a self-administered questionnaire. From December 2016 to March 2017, we sampled undergraduate and graduate students aged 20 or older at 35 colleges in the Kanto area, including Tokyo. The following items were measured: 1) frequency of drinking; 2) frequency of binge drinking in the past year; 3) nomihodai use; 4) the number of drinks consumed when using or not using nomihodai; and 5) sex and age for demographic data. Paired t-test was used to compare means between use and non-use state of nomihodai. The Fisher’s exact test was used to evaluate the significance of the distribution difference between the two types of states. A total of 511 subjects completed the questionnaire, including 274 men and 237 women. The amount of drinking was increased 1.8-fold (85.9 ± 49.7 g vs. 48.2 ± 29.5 g) among men and 1.7-fold (63.7 ± 39.3 g vs. 36.5 ± 26.7 g) among women during nomihodai use, comapred with non-use states. Among them, 109 (39.8%) men and 71 (30.3%) women reported HED only at nomihodai states. These data suggest that the use of nomihodai system may lead to excessive drinking among college students.

NIRS measurement was carried out in a confinement experiment for the first time. A tendency for NIRS integrated values to decrease was observed. Problems such as the learning effect needed to be resolved. SOC had an upward trend. Regarding POMS, the first day of confinement showed the highest score, after which no obvious deterioration was seen.

Over the past few years, the number of Japanese astronauts recruited for a long-term stay in the International Space Station (ISS) has increased. Being on a prolonged mission with the same people, in the same room, should impose psychosocial stress on the astronauts, possibly causing feelings of “psychological suffocation”. Several confinement studies have been conducted to simulate the conditions of the ISS, the Mir space station, and potential habitats on Mars, and to survey psychological interpersonal communication between the crew in a confined environment, including the Isolation Study for European Manned Space Infrastructure, Experimental Campaign for the European Manned Space Infrastructure, Simulation of Flight of International Crew on Space Station, Human Behavior in Extended Spaceflight, Mars-500, and Hawaii Space Exploration Analog and Simulation. Here, the findings from these studies were integrated into a structured review according to an evidence-based set of items for reporting in systematic reviews and meta-analyses. The results indicated that metaanalyses would not always be appropriate because it is difficult to design a research protocol with a high level of evidence in this field. Therefore, future research in this field should be focused on the following three points: 1) developing more accurate parameters for monitoring stress levels in long-term confinement environments; 2) analyzing stress levels in such situations with higher precision; and 3) accumulating and assembling existing and future data from long-term confinement environments.
