     View Summary

    Millions of consumer sport and fitness wearables (CSFWs) are used worldwide, and millions of datapoints are generated by each device. Moreover, these numbers are rapidly growing, and they contain a heterogeneity of devices, data types, and contexts for data collection. Companies and consumers would benefit from guiding standards on device quality and data formats. To address this growing need, we convened a virtual panel of industry and academic stakeholders, and this manuscript summarizes the outcomes of the discussion. Our objectives were to identify (1) key facilitators of and barriers to participation by CSFW manufacturers in guiding standards and (2) stakeholder priorities. The venues were the Yale Center for Biomedical Data Science Digital Health Monthly Seminar Series (62 participants) and the New England Chapter of the American College of Sports Medicine Annual Meeting (59 participants). In the discussion, stakeholders outlined both facilitators of (e.g., commercial return on investment in device quality, lucrative research partnerships, and transparent and multilevel evaluation of device quality) and barriers (e.g., competitive advantage conflict, lack of flexibility in previously developed devices) to participation in guiding standards. There was general agreement to adopt Keadle et al.'s standard pathway for testing devices (i.e., benchtop, laboratory, field-based, implementation) without consensus on the prioritization of these steps. Overall, there was enthusiasm not to add prescriptive or regulatory steps, but instead create a networking hub that connects companies to consumers and researchers for flexible guidance navigating the heterogeneity, multi-tiered development, dynamicity, and nebulousness of the CSFW field.

     View Summary

    BACKGROUND: In an effort to increase people's adherence to active lifestyles, contemporary physical activity (PA) guidelines now include low-dose PA. METHODS: PA was evaluated in 583 participants of the Nutritional and Physical Activity Intervention Study (NEXIS) cohort (30-65 years old); 349 inactive participants (MVPA, 2.7 ± 1.0 MET-h/day) were randomly assigned to the intervention or control groups, and 235 active participants participated in follow-up visits. The intervention aimed to increase MVPA and comprised five brief counseling sessions over 1 year. The 1-year target for the participant was increasing their step-count to 10,000 steps/d or +3000 steps/d, relative to the baseline score. The counseling sessions were designed to stimulate progressive changes in physical behaviors by recommendations promoting small and/or light-intensity bouts of PA. PA was measured at baseline, the end of the intervention, and 1 year after the intervention ended. Additionally, several nutrition, health, and fitness parameters were measured. RESULTS: Participants in the intervention group significantly increased their step-count from 8415 ± 1924 at baseline to 9493 ± 2575 at the end of the 1-year period. During the same period, MVPA significantly increased by 0.9 MET-h. The daily time spent in ≥ 3, ≥ 4 and ≥ 5 MET activities increased by 11, 6, and 3 min, respectively. This increase in PA remained observable 1 year after intervention concluded. The active group maintained higher physical activity levels throughout the two years. The intervention group showed smaller energy intakes at the end of the 2-year period. Significant correlations were noted between the 1-year change in MVPA and the change in resting heart rate (r =  - 0.22), and between the 2-year change in MVPA and the change in waist circumference (r =  - 0.08) and peak oxygen consumption capacity (r = 0.23) in the intervention group only. CONCLUSIONS: A prolonged and progressive PA intervention promoting small bouts of light-to-moderate PA may be used in healthy, not-optimally-active people to increase PA beyond the strict period of the intervention. Further studies are necessary to understand whether low-dose PA messages can be effective in initiating a progressive increase toward larger amounts of PA.

    BACKGROUND & AIMS: A limited number of studies have developed simple anthropometric equations that can be implemented for predicting muscle mass in the local community. Several studies have suggested calf circumference as a simple and accurate surrogate maker for muscle mass. We aimed to develop and cross-validate a simple anthropometric equation, which incorporates calf circumference, to predict appendicular skeletal muscle mass (ASM) using dual-energy X-ray absorptiometry (DXA). Furthermore, we conducted a comparative validity assessment of our equation with bioelectrical impedance analysis (BIA) and two previously reported equations using similar variables. METHODS: ASM measurements were recorded for 1262 participants (837 men, 425 women) aged 40 years or older. Participants were randomly divided into the development or validation group. Stepwise multiple linear regression was applied to develop the DXA-measured ASM prediction equation. Parameters including age, sex, height, weight, waist circumference, and calf circumference were incorporated as predictor variables. Total error was calculated as the square root of the sum of the square of the difference between DXA-measured and predicted ASMs divided by the total number of individuals. RESULTS: The most optimal ASM prediction equation developed was: ASM (kg) = 2.955 × sex (men = 1, women = 0) + 0.255 × weight (kg) - 0.130 × waist circumference (cm) + 0.308 × calf circumference (cm) + 0.081 × height (cm) - 11.897 (adjusted R2 = 0.94, standard error of the estimate = 1.2 kg). Our equation had smaller total error and higher intraclass correlation coefficient (ICC) values than those for BIA and two previously reported equations, for both men and women (men, total error = 1.2 kg, ICC = 0.91; women, total error = 1.1 kg, ICC = 0.80). The correlation between DXA-measured ASM and predicted ASM by the present equation was not significantly different from the correlation between DXA-measured ASM and BIA-measured ASM. CONCLUSIONS: The equation developed in this study can predict ASM more accurately as compared to equations where calf circumference is used as the sole variable and previously reported equations; it holds potential as a reliable and an effective substitute for estimating ASM.

     View Summary

    The association between a dietary pattern characterised by high alcohol intake and dyslipidaemia has not been fully investigated. Therefore, the present study aimed to investigate the association between alcohol dietary patterns and the prevalence of dyslipidaemia and its components. This cross-sectional study enrolled 2,171 men and women aged ≥40 years who were alumni of a Japanese university. To identify dietary patterns, a principal component analysis was performed based on the energy-adjusted food intake estimated by a brief-type self-administered diet history questionnaire. Three dietary patterns were identified, the second of which was named the alcohol dietary pattern and was characterised by a high intake of alcoholic beverages, liver, chicken, and fish. This alcohol dietary pattern was associated with reduced low-density lipoprotein cholesterol (LDL-C) levels. The fully adjusted odds ratios (95% confidence intervals) of high LDL-C for the lowest through highest quartile of alcohol dietary pattern score were 1.00 (reference), 0.83 (0.64-1.08), 0.84 (0.64-1.10), and 0.68 (0.49- 0.94), respectively. Subgroup analysis showed that the alcohol dietary pattern was inversely associated with the prevalence of dyslipidaemia in women, whereas it was positively associated with high triglyceride levels in men. In conclusion, the alcohol dietary pattern, characterised by a high intake of alcoholic beverages, liver, chicken, and fish, was associated with the prevalence of dyslipidaemia and its components. This finding provides useful information for the prevention and treatment of dyslipidaemia by modifying the diet.

    本研究は、持久性運動開始3時間前の食事摂取の有無が、運動開始直前の糖質摂取による低血糖の発生に及ぼす影響を明らかにすることと、運動開始直前の糖質摂取による低血糖を規定する要因を明らかにすることを目的として行った。16名の若年日本人男性を対象として、運動開始3時間前に朝食を摂取する条件と、一晩絶食の条件において、150gのグルコースを摂取した30分後に、最大酸素摂取量の75%の強度で60分の自転車運動を行った。両条件において、運動開始15分後における血糖値の平均値は低血糖の基準である70mg/dLを下回らなかったが、朝食摂取条件では7名、絶食条件では5名において低血糖が起こった。朝食摂取条件において、低血糖が起こった者は、正常血糖の者と比較して最大酸素摂取量が有意に高く、絶食条件においては、運動開始直前のインスリン濃度とインスリン分泌指標が高かった。以上の結果より、若年日本人男性において、摂食状況に関わらず、運動開始直前の糖質摂取により低血糖が起こる者がいることが明らかになった。また、運動3時間前に食事を摂取した状態においては最大酸素摂取量が、一晩絶食の状態においては、インスリン初期分泌反応が高い者において、低血糖が起こりやすい可能性が示唆された。(著者抄録)

    本研究の目的は、個々の2型糖尿病の発症パターンを早期に予測するため、2型糖尿病の主要な成因であるインスリン分泌能低下とインスリン抵抗性を予測するための遺伝的リスクスコア(Genetic risk score: GRS)を構築し、GRSによる2型糖尿病発症パターンの分類を行うことと、これらGRSが2型糖尿病発症に及ぼす影響は、どのような生活習慣・身体特性を有する者において弱まるかを明らかにすることである。本年度は、2型糖尿病の既往歴のない中高齢者において、昨年度までに構築したインスリン分泌能低下を予測する遺伝的リスクスコア(insulin secretion-GRS [IS-GRS])とインスリン分泌能および空腹時血糖値との関連は、全身持久力が高い者において弱まるかどうか、また、それらの関連はBMIが低い者においても認められるかどうかを明らかにすることを目的として研究を行った。
    2型糖尿病の既往歴のない中高齢者882名を対象とした横断研究を行った。IS-GRSはインスリン分泌能との関連が報告されている20個のSNPより求めた。全身持久力は最大酸素摂取量の測定により評価した。BMIの中央値(BMI = 22.6 kg/m2)で対象者を高BMI群と低BMI群に分類し、それぞれの群において解析を行った。その結果、高BMI群においてIS-GRSと全身持久力との間に有意な交互作用が認められ、全身持久力が低い者においてはIS-GRSとインスリン分泌能および空腹時血糖値との間に有意な関連が認められたが、全身持久力が高い者においてはこれらの関連は認められなかった。しかし、低BMI群においてこれらの交互作用は認められなかった。
    以上の結果より、インスリン分泌能と空腹時血糖値に及ぼす遺伝要因の影響は、BMIが低い者においては高い全身持久力を有していても弱まらない可能性が示唆された。
