Background In knee osteoarthritis (OA), pain is the most frequent and dominant symptom. However, which factors other than radiological changes contribute to the symptoms is unresolved. The aims of this study were to identify factors affecting knee pain from various variables with radiological changes taken into count and exploratively examine what subgroups or phenotype could be identified by cluster analysis using the identified knee pain factors. Methods Patients 60 years or older who underwent radiographic evaluation were included in this cross-sectional study, and those subjects who completed a questionnaire about knee symptoms without missing data were eligible for analysis. Multiple regression analysis was used to examine the associations between selected variables and The Japanese Knee Osteoarthritis Measure (JKOM) pain score. We grouped the subjects by cluster analysis using identified variables. Results Two thousand five hundred forty-two subjects were included in the full set of analyses. Age, body mass index (BMI), radiological grade, bone mineral density (BMD), and high-sensitivity C-reactive protein (hs-CRP) showed a statistically significant correlation with radiological showing the strongest value. For dichotomous variable, presence of depression showed a statistically significant result. We used BMI, radiological grade, BMD, hs-CRP, and presence of depression as a variable for cluster analysis and identified six subgroups: (1) minimal joint disease subgroup, (2) male and high BMD subgroup, (3) high CRP subgroup, (4) severe radiological OA subgroup, (5) depressive subgroup, and (6) moderate radiological OA with high BMI subgroup, showing the worst knee outcome. Conclusion This study identified the factors affecting knee pain other than radiological changes and identified six subgroups of knee outcome in the general population. The results showed that obesity with radiological changes or depression was associated with worse knee outcome.

Aim Nocturia is a common phenomenon in older individuals, and is associated with poor quality of life. Nocturia is a multifactorial disorder, wherein the frailty of skeletal muscles, particularly muscle weakness in the lower trunk and hip regions, might be a risk factor in women. We analyzed a dataset of the general Japanese population to clarify the hypothesis. Methods Study participants included 1207 older women (mean age 67.4 ± 5.2 years). The frequency of nocturnal urination was assessed using a sleep diary for 1 week, and associations with lower muscle strength, skeletal muscle index, sarcopenia and physical performance (one‐leg standing time and Timed Up and Go test) were investigated. Results The frequency of nocturnal urination more than one voiding per night was 28.1%; this frequency was inversely associated with hip abduction strength quartiles (Q1: 37.0, Q2: 30.5, Q3: 25.1 and Q4: 19.9%, P < 0.001). When a sleep diary‐based nocturnal urination frequency >1.5 times/night (corresponding to a ≥2 times/night frequency obtained by questionnaire) was considered as nocturia, logistic regression analysis adjusted for major covariates identified hip abduction strength as an independent inverse determinant of nocturia (odds ratio 0.75, 95% CI 0.52–0.90, P = 0.002). In contrast, no significant association was observed with knee extension (P = 0.322) and hip flexion (P = 0.603) strengths. Physical performance, skeletal muscle index and sarcopenia did not show significant associations with nocturia. Conclusions Weak hip abduction strength might be a factor associated with nocturnal urination frequency in older women. Geriatr Gerontol Int 2019; 19: 1010–1016.

“…Furthermore, nocturia may increase mortality risk mainly by increasing the incidence of falls and fractures . We previously reported that individuals with frequent night‐time urination had a smaller dip in nocturnal blood pressure (BP) . Because smaller BP dipping during sleep is an independent risk factor for cardiovascular disease and mortality, the association between nocturia and mortality may at least partly result from abnormalities in the circadian BP variation.…”

“…5,6 We previously reported that individuals with frequent night-time urination had a smaller dip in nocturnal blood pressure (BP). 7 Because smaller BP dipping during sleep is an independent risk factor for cardiovascular disease and mortality, 8 the association between nocturia and mortality may at least partly result from abnormalities in the circadian BP variation. Interventions that reduce nocturnal urine production and consequently improve nocturia may, therefore, contribute not only to improving the quality of life but also to reducing the mortality risk.…”

Background Nocturia is a risk factor for poor quality of life and increased mortality. This study was aimed to clarifying dietary habits, eating behaviors, and sleep characteristics associated with nocturia to identify modifiable lifestyle factors for nocturia. Methods This cross‐sectional study included 5683 community residents (64.5 ± 7.7 years old). The frequency of nocturnal urination was recorded for 1 week using a sleep diary. The frequency of food intake, unfavorable eating behaviors, and sleep characteristics that may have influence on salt intake and wasting were obtained using a structured questionnaire. Results The frequency of nocturnal urination was increased with age (β = .312, P < .001). Other basic factors associated with the frequency were the male sex (β = .090), hypertension (β = .038), sleep apnea (β = .030), B‐type natriuretic peptide level (β = .089), and spot urine sodium excretion (β = −.058). Dietary factors independently associated with nocturnal urination frequency were coffee (≥1 time/day: β = −.059, P < .001) and green vegetable consumption (≥1 time/week: β = −.042, P = .001), whereas habitual intake of dairy products, miso soup, and alcohol were not associated with urination frequency. Later bedtime was inversely associated with nocturnal urination frequency independent of sleep duration (before 23:00: β = −.096; before 24:00: β = −.225; after midnight: β = −.240; all P < .001). Conclusion Coffee and green vegetable consumption and later bedtime but not sleep duration are lifestyle factors associated with nocturnal urination frequency.
