We confirmed the reliability and validity of the Japanese version of the abbreviated LSNS-6.

The prognostic significance of white-coat hypertension (WCHT) is controversial, and different findings on self-measured home measurements and 24-h ambulatory monitoring make identifying WCHT difficult. We examined whether individuals with partially or completely defined WCHT, as well as masked hypertension, as determined by different out-of-office blood pressure measurements, have a distinct long-term stroke risk. We followed 1464 participants (31.8% men; mean age, 60.6±10.8 years) in the general population of Ohasama, Japan, for a median of 17.1 years. A first stroke occurred in 212 subjects. Using sustained normal blood pressure (events/n=61/776) as a reference, adjusted hazard ratios for stroke (95% confidence intervals; events/n) were 1.38 (0.82–2.32; 19/137) for complete WCHT (isolated office hypertension), 2.16 (1.36–3.43; 29/117) for partial WCHT (either home or ambulatory normotension with office hypertension), 2.05 (1.24–3.41; 23/100) for complete masked hypertension (both home and ambulatory hypertension with office normotension), 2.08 (1.37–3.16; 38/180) for partial masked hypertension (either home or ambulatory hypertension with office normotension), and 2.46 (1.61–3.77; 42/154) for sustained hypertension. When partial WCHT and partial masked hypertension groups were further divided into participants only with home hypertension and those only with ambulatory hypertension, all subgroups had a significantly higher stroke risk (adjusted hazard ratio ≥1.84, P ≤0.04). In conclusion, impacts of partial WCHT as well as partial masked hypertension for long-term stroke risk were comparable to those of complete masked hypertension or sustained hypertension. We need both home and 24-h ambulatory blood pressure measurements to evaluate stroke risk accurately.

We investigate associations of fruit and vegetable intake with the risk of future hypertension using home blood pressure in a general population from Ohasama, Japan. We obtained data from 745 residents aged X35 years without home hypertension at baseline. Dietary intake was measured using a validated 141-item food frequency questionnaire, and subjects were then divided into quartiles according to the fruit and vegetable intake. Home hypertension was defined as home systolic/ diastolic blood pressure of X135/85 mm Hg and/or the use of antihypertensive medication. During a 4-year follow-up period, we identified 222 incident cases of home hypertension. After adjustment for all putative confounding factors, the highest quartile of fruit intake was associated with a significantly lower risk of future home hypertension (odds ratio 0.40, 95% confidence interval 0.22-0.74, P ¼ 0.004). In conclusion, this study, based on home blood pressure measurement, suggests that higher intake of fruit is associated with a lower risk of future home hypertension.

Higher protein, particularly animal protein, was associated with lower risk of decline in higher-level functional capacity in older men. Animal protein intake may be a modifiable indicator for early detection and prevention of higher-level functional decline in elderly adults.
