RESUMEN
BACKGROUND: We designed a quick simple exercise program that can be performed in a short period of time in real-world occupational health settings and investigated the effects of three months of program implementation on non-specific low back pain (NSLBP). METHODS: Participants were 136 individuals working in the manufacturing industry. The quick simple exercise program was designed to be doable in three minutes and consisted of two exercises: a hamstring stretch and a lumbar spine rotation with forward, backward, and lateral flexion. This was a randomized controlled trial incorporating an intervention group to whom the exercises were recommended within a leaflet, and a control group to whom the exercises were not recommended. NSLBP was evaluated at baseline and after three months using numerical rating scale (NRS) scores, ranging from 0 points (no pain at all) to 10 points (worst pain imaginable). The percentages of cases that improved by a minimal clinically important difference (two points or above) were compared. RESULTS: Overall, 76.1% of the intervention group participants performed the quick simple exercises at least once every one or two days. Three months after baseline, a significantly higher percentage of participants in the intervention group (17 participants: 25%) had NSLBP improvement of two or more points on the NRS compared to that in the control group (8 participants, 12%) (P = 0.047). The average NRS score decreased significantly from 1.87 ± 1.86 to 1.33 ± 1.60 in the intervention group but showed no significant change in the control group, transitioning from 1.46 ± 1.73 to 1.52 ± 1.83. A significant interaction was also observed between the intervention and control groups (F = 6.550, P = 0.012). CONCLUSIONS: Three months of a quick simple exercise program among workers in the manufacturing industry increased the percentage of workers with improvement in the NRS scores. This suggests that the program is effective in managing NSLBP in workers in the manufacturing industry. TRIAL REGISTRATION: UMIN-CTR UMIN000024117.

BACKGROUND: Physical activity (PA) that includes an accumulated exercise regimen that meets or exceeds a certain intensity reduces intrahepatic fat, leading to the improvement of nonalcoholic fatty liver disease (NAFLD) in afflicted patients. However, whether an increase in comprehensive PA, including activities of daily living, contributes to ameliorating the pathophysiology of NAFLD remains unclear. This study aimed to examine whether PA improves liver function in patients with NAFLD. METHODS: The study included 45 patients with NAFLD who underwent follow-up examinations at least 6 months-but no later than 1 year-after their baseline examinations. The patients were interviewed about their daily activities and exercise habits to determine whether they had engaged in at least 3 metabolic equivalents (METs) per day during the previous 6 months; the quantity of PA, expressed in Ekusasaizu (Ex) units, was calculated as METs multiplied by hours. Patients who had achieved at least a 1-Ex increase in PA per week compared to baseline at the time of their follow-up interview (the PA increase group) were compared to those whose PA was the same or lower at the time of follow-up (the PA non-increase group). RESULTS: There were no significant changes in all blood and biochemical parameters in the PA non-increase group at the time of follow-up when compared with baseline levels. In the PA increase group, aspartate aminotransferase, alanine aminotransferase, and γ-guanosine triphosphate levels were all significantly lower at follow-up than they were at baseline. Body weight did not change significantly from baseline to follow-up in both groups. CONCLUSIONS: In the present study, hepatic inflammation improvement was accompanied by increased PA but not decreased body weight. Increasing PA may be effective for the improvement of hepatic inflammation even without body weight loss. Our results indicate the effectiveness of PA monitoring for the management of NAFLD.

BACKGROUND: High prevalence of low back pain (LBP) in nurses has been reported globally. Ergonomic factors and work-related psychosocial factors have been focused on as risk factors. However, evidence on the role of fear-avoidance beliefs (FABs) concerning LBP in nurses is lacking. This study examined LBP prevalence and the association between FABs and chronic disabling LBP that interfered with work and lasted ≥ 3 months. METHODS: Female nurses (N = 3066; mean age = 35.8 ± 10.6 years) from 12 hospitals in Japan participated. A self-reported questionnaire was used to collect information on sociodemographics, LBP, work-related factors, and psychological distress. FABs about physical activity were assessed using a subscale from the FAB Questionnaire (score range = 0-24). The participants were asked to choose one of four statements regarding their LBP in the past 4 weeks: 1) I did not have LBP, 2) I had LBP without work difficulty, 3) I had LBP with work difficulty but without requiring absence from work, and 4) I had LBP requiring absence from work. If the participant had LBP in the past 4 weeks, it was also inquired if the LBP had lasted for ≥ 3 months. Chronic disabling LBP was defined as experiencing LBP with work difficulty in the past 4 weeks which had lasted for ≥ 3 months. In the nurses who had experienced any LBP in the past 4 weeks, we examined the association between FABs and experiencing chronic disabling LBP using multiple logistic regression models adjusting for pain intensity, age, body mass index, smoking status, psychological distress, hospital department, weekly work hours, night shift work, and the12 hospitals where the participants worked. RESULTS: Four-week and one-year LBP prevalence were 58.7 and 75.9%, respectively. High FABs (≥ 15) were associated with chronic disabling LBP (adjusted odds ratio = 1.76, 95% confidence interval [1.21-2.57], p = 0.003). CONCLUSIONS: LBP is common among nurses in Japan. FABs about physical activity might be a potential target for LBP management in nurses. TRIAL REGISTRATION: UMIN-CTR UMIN000018087. Registered: June 25, 2015.

Objectives: To evaluate the 'One Stretch' exercise's effect on improvements in low back pain (LBP), psychological factors, and fear avoidance in a large number of nurses. Methods: Between July 2015 and June 2016, we performed a prospective, randomized, parallel-group, multi-center study with central evaluations. Eligible patients were randomly assigned (1:1:1 ratio) to either the control group (Group A) or an intervention group (Group B: 30-min seminar about the 'One Stretch' exercise, Group C: B + physical and psychological approaches to LBP treatment). The primary outcome was subjective improvement from baseline to 6 months (improved/unchanged/worsened) and overall exercise habits (good/poor). Results: There were 4767 participants: 1799, 1430, and 1548 in Groups A, B, and C, respectively. We collected data on 3439 participants (949, 706, and 751 in Groups A, B, and C, respectively) at the 6-month follow-up. The improvement rates in Groups A, B, and C were 13.3%, 23.5%, and 22.6%, respectively. The worsened pain rates were 13.0%, 9.6%, and 8.1%, which decreased as the intervention degree increased (the Cochran-Armitage trend test: p < .0001). In Groups A, B, and C, 15.6%, 64.9%, 48.8% of the patients, respectively, exhibited exercise habits. Conclusion: The 'One Stretch' exercise is useful for improving LBP.

The increase in the proportion of elderly people in the population is one of the most remarkable sociodemographic phenomena of the twenty-first century. The number of patients with diabetes is also increasing worldwide with this demographic change. Given these facts, consideration of the problems the general elderly population is facing in the management of diabetes is essential. In this review article, we focus on sarcopenia, which is the decrease in lower extremity muscle mass and muscle strength accompanying aging, describe the relationship between sarcopenia and diabetes, and highlight the specific factors through which diabetes contributes to loss of muscle strength. The quantitative methods for evaluating lower extremity muscle strength will also be described. These methods hold the key to assessing the effectiveness of exercise therapy and optimizing the assessment of the degree of autonomy in the activities of daily living. Exercise is one of the basic treatments for type 2 diabetes and may also prevent and improve sarcopenia. This review discusses the aspects common to the two health conditions and elucidates the effectiveness and necessity of exercise as a preventive measure against diabetes among the elderly.

[Purpose] This study assessed the effects of type 2 diabetes without diabetic polyneuropathy on muscle strength according to body composition in middle age patients. [Subjects and Methods] This study included 45 non-diabetic individuals (control group) and 50 patients with type 2 diabetes (DM group), 40 to 64â years of age. The body composition was examined, including the leg muscle volume (LMV), which was the sum of the lower-limb muscle mass. The muscle strength was also examined, and the knee extension force (KEF), ankle dorsiflexion force (ADF). The KEF and ADF were normalized to the bodyweight, and the total leg muscle force (TLMF) were calculated by combining the KEF and ADF. The leg muscle quality (LMQ) was calculated as the TLMF normalized with the LMV. [Results] While no significant differences were found in the LMV between groups, the body mass index were higher in the DM group than in the control group. Significant differences were observed in %KEF, %ADF, and the LMQ in the DM group, with 15.8%, 18.7%, and 11.5% lower values than those in the control group, respectively. [Conclusion] The results of this study may demonstrate that muscle weakness occurs before diabetes progresses to a severe condition.
RESUMEN
[Purpose] The purpose of this study is to investigate the factors causing falling among patients with schizophrenia hospitalized in psychiatric hospitals. [Subjects and Methods] The study subjects were divided into either those having experienced a fall within the past one year (Fall group, 12 patients) and those not having experienced a fall (Non-fall group, 7 patients), and we examined differences between the two groups. Assessment items measured included muscle strength, balance ability, flexibility, body composition assessment, Global Assessment of Functioning scale (GAF), the antipsychotic drug intake, and Drug Induced Extra-Pyramidal Symptoms Scale (DIEPSS). [Results] As a result, significant differences were observed in regard to One leg standing time with eyes open, Time Up and Go Test (TUGT), and DIEPSS Sialorrhea between the Fall group and the Non-fall group. [Conclusion] These results suggest that a decrease in balance ability was significantly correlated with falling in schizophrenia patients.
RESUMEN
[Purpose] There is insufficient evidence related to exercise programs that are safe and efficacious for pregnant women with abnormal glucose metabolism. Tai Chi Yuttari-exercise is an exercise program with validated safety and efficacy in improving physical function in the elderly. In this study, we investigated this program's inhibitory effects on plasma glucose elevation when it was adapted to a pregnancy model. [Subjects and Methods] Twelve 18- to 19-year-old females without a history of pregnancy were randomly assorted into two groups: an intervention group, for which six subjects were outfitted with mock-pregnancy suits and asked to perform Tai Chi Yuttari-exercise, and a control group who did not perform exercise. The intervention group had a mean Borg Scale score of 11.1 ± 0.9 during the exercise. [Results] No significant intragroup differences were observed in fasting, baseline, or post-intervention/observation plasma glucose levels. On the other hand, the intergroup change in plasma glucose levels after intervention/observation was significant when comparing the intervention and control groups: -1.66 ± 7.0 and 9.42 ± 6.57â mg/dl, respectively. [Conclusion] Tai Chi Yuttari-exercise appears to effectively inhibit plasma glucose elevation at intensity and movement levels that can be safely applied to pregnant women with abnormal glucose metabolism.
RESUMEN
A 72-year-old woman with chronic myeloid leukemia with T315I mutation in breakpoint cluster region-abelson (BCR-ABL) was treated with ponatinib. During the course of her treatment, chronic limb-threatening ischemia developed in both lower extremities, and the left lower extremity was amputated below the knee at a previous hospital. She was referred to our department for salvage of the right lower extremity. We performed a foot bypass and multidisciplinary treatment of the wound, and achieved epithelialization in about 1 month. The rate of vascular occlusive events with ponatinib has been reported to be high, and we believe that careful monitoring is important during use.
RESUMEN
This study investigated whether the progression of liver fibrosis affects the prevalence of sarcopenia and incidence of decreased gait speed in older patients with chronic liver disease (CLD). Patients with CLD aged ≥ 60 years were classified into low, intermediate, and high fibrosis 4 (FIB-4) index groups according to the degree of liver fibrosis. The prevalence of sarcopenia and incidence of decreased gait speed (< 1.0 m/s) were compared among the three groups. Logistic regression analysis was performed to investigate factors affecting the risk of decreased gait speed. No significant difference was observed in the prevalence of sarcopenia among the three groups, but the incidence of decreased gait speed significantly differed (p = 0.029). When analyzed individually, a significant difference in decreased gait speed incidence was observed between the high and low FIB-4 index groups (p = 0.014). In logistic regression analysis, the progression of liver fibrosis (odds ratio: 1.32, 95% confidence interval: 1.13-1.55) and lower extremity muscle strength (LEMS) (odds ratio: 0.92, 95% confidence interval: 0.88-0.97) were significantly associated with decreased gait speed. As liver fibrosis progresses in older patients with CLD, it becomes important to focus on not only skeletal muscle mass and grip strength, but also gait speed and LEMS.

Few studies have examined the effects of different aerobic-exercise intensities on intraocular-pressure (IOP) changes. This may be important for eye diseases that are impacted by IOP or its fluctuation, including glaucoma, and diabetes that is complicated by diabetic retinopathy. We investigated the effects of low-, moderate-, and high-intensity exercise on IOP in healthy subjects. A submaximal cardiopulmonary exercise test was performed in 18 healthy male subjects, and the maximal oxygen uptake was calculated. The subjects then exercised for 20 min at 30%, 50%, and 70% ·VO2 of maximal oxygen uptake, and their IOP was measured at rest and every 5 min during exercise. Oxygen uptake was monitored using an expiratory gas analyzer during exercise to maintain accurate exercise intensity and adjust exercise load. Oxygen uptake during exercise was significantly higher at all intensities from 5 to 20 min than at rest. IOP was significantly lower at 70% exercise intensity from 5 to 20 min than at rest. A negative correlation existed between IOP and ·VO2. IOP remained unchanged during low- and moderate-intensity exercise but significantly declined during high-intensity exercise compared with that at rest. Although various factors, such as ß-blockers, are involved in IOP decline at rest, a different mechanism is involved in IOP decline during exercise.
RESUMEN
AIMS/INTRODUCTION: Diabetic polyneuropathy (DPN) is a factor that reduces lower extremity muscle strength (LEMS) in older type 2 diabetes patients. This relationship remains unclear in longitudinal studies. Therefore, we longitudinally investigated the apparent effects of DPN on changes in LEMS. Furthermore, we cross-sectionally examined relationships among DPN, LEMS, mobility and health-related quality of life. MATERIALS AND METHODS: Bodyweight-normalized (relative) knee extension force (KEF) was examined in 51 DPN and 54 non-DPN patients (68.9 ± 5.6 and 70.2 ± 5.9 years, respectively) at baseline and follow up at 3.6 ± 0.6 years. At follow up, mobility was measured using a 25-question geriatric locomotive function scale. Health-related quality of life was assessed using the five-dimensions of EuroQol for quality-adjusted life years calculation. RESULTS: Relative KEF in the DPN group was significantly lower at follow up (1.22 ± 0.47 Nm/kg) than at baseline (1.31 ± 0.47 Nm/kg; P < 0.05). DPN significantly affected changes in relative KEF. Mobility decreased by 41 and 65% in the non-DPN and DPN groups, respectively. Quality-adjusted life years were significantly lower in the DPN group (0.856 ± 0.131) than in the non-DPN group (0.920 ± 0.105; P < 0.01). Relative KEF was a significant independent variable that explained quality-adjusted life years. CONCLUSIONS: DPN clearly reduced LEMS in older type 2 diabetes patients within 4 years. Furthermore, DPN resulted in a loss of LEMS and decrease in mobility. Therefore, DPN development should be monitored closely, with glycemic control and LEMS kept at a high level to maintain health-related quality of life in older patients with type 2 diabetes.

OBJECTIVE: This study aimed to adapt a pre-existing cross-country comparison (CCC) model to Occupational Health Physiotherapy (OHP) practice as a basis for locating and examining contextual factors that may influence OHP practice in Japan and Australia. METHOD: A secondary analysis was conducted of existing publicly-available data on OHP and related influential factors, following the five components of the CCC model: work-related legislation; labor market characteristics; culture; physiotherapy practice norms; and organization of OHP practice. RESULTS: Legislation in both countries promotes safe work and rehabilitation of work injured/ill workers. 2019 unemployment was lower in Japan with higher employment protection than Australia. Both countries have an ageing workforce and rising retirement age. Cultural differences relate to higher long-term orientation and uncertainty avoidance in Japan. Australia has higher individualism and physiotherapists are autonomous practitioners with direct access, which differs from Japan. Both countries have a national OHP subgroup, to date only Australia has OHP professional practice standards. DISCUSSION: This study is the first to compare OHP practice in Japan and Australia. Contextual similarities and differences observed may underpin OHP practitioner role and its enhancement in work-related musculoskeletal disorder prevention and management strategies, the return-to-work process, and development of this physiotherapy discipline nationally. CONCLUSION: Adapting the CCC model to OHP practice enabled a structured exploration of resources and data, from which to extract and compare contextual factors that may shape OHP practice in Japan and Australia. This in turn may provide a useful springboard for further discussion about OHP practice internationally.
RESUMEN
OBJECTIVES: This non-randomized controlled study investigated the impact of practicing Tai Chi Yuttari-exercise for 1 year on arteriosclerosis status and physical functioning of community-dwelling older people. METHODS: Vascular and physical function were compared between 45 and 44 individuals who had and had not participated in Tai Chi Yuttari classes for 1 year, respectively. Participants deemed unsuitable for exercise by a physician, unable to walk unaided, with severely limited activities of daily living, with serious circulatory or respiratory disease, undergoing treatment for an acute or chronic motor organ disease, with seriously impaired motor function of the upper or lower limbs, with a history of myocardial infarction or cerebral stroke within the previous 6 months, and with previous serious infection were excluded. RESULTS: The mean cardio-ankle vascular index improved significantly from 8.44 at baseline to 8.20 after 6 months in the intervention group; however, no significant difference was observed at 1 year. Conversely, compared with baseline, the functional reach, gait speed, and timed up-and-go test results improved significantly after 6 months in this group; these improvements were maintained after 1 year. No significant changes in arteriosclerosis or physical function were observed in the control group. CONCLUSIONS: The practice of Tai Chi Yuttari-exercise is effective in maintaining and improving arteriosclerosis status and physical function in older people. However, it may be performed at least thrice a week for maintaining or improving arteriosclerosis status.

INTRODUCTION: Progression of muscle strength weakening will lead to a poor physical performance and disability. While this is particularly important in patients with diabetes, the associations of reduced muscle strength measured by grip strength with clinical features and physical performance remain unclear. We investigated clinical features and physical performance measures in association with grip strength in elderly people with diabetes in a primary care setting. RESEARCH DESIGN AND METHODS: A cross-sectional study was conducted enrolling 634 male and 323 female Japanese patients with type 2 diabetes aged 60 years or older. First, grip strength was measured and the associations of gender-specific grip strength with clinical features were evaluated. Second, in patients with a grip strength below the gender-specific median, physical performance measures, including gait speed, timed chair stand speed, knee extension strength, standing balance, and short physical performance battery scores, were investigated. Patients with and without a low performance defined by Asian Working Group for Sarcopenia were compared in terms of clinical features and physical performance measures. RESULTS: Grip strength decreased according to aging and longer duration of diabetes and was independently related to body mass index, glycated hemoglobin A1c (HbA1c), serum albumin, albuminuria, neuropathy, and stroke in male patients, and to body mass index and albuminuria in female patients. The physical performance measures became worse proportionally to a decrease in the grip strength. Patients with a low performance exhibited a significantly older age, lower grip strength and serum albumin, higher albuminuria, and poorer physical performance measures than those without. CONCLUSIONS: Reduced grip strength was associated with glycemic exposure indicators of age-related duration, HbA1c, and vascular complications. The physical performance measures became worse with decreasing grip strength. Measurements of grip strength and physical performance in patients with diabetes may help promote intervention to prevent frailty in future studies.

OBJECTIVES: To determine standard reference values for isometric knee extension force using a cohort of Japanese type 2 diabetic patients without diabetic polyneuropathy. METHODS: Patient data were collected from the Multicenter Survey of the Isometric Lower Extremity Strength in Type 2 Diabetes study and compared with previously published data of healthy control subjects. In total, we enrolled 898 patients with type 2 diabetes aged 30-87 years, who did not have diabetic polyneuropathy. The control group included 510 healthy subjects aged 30-88 years. Maximum isometric knee extension force (KEF) values were obtained by using a hand-held dynamometer with belt stabilization. In addition, KEF (kgf) was adjusted for bodyweight (kg) to calculate %KEF. RESULTS: KEF and %KEF decreased with age in both patients with diabetes and healthy control subjects. The mean values of KEF and %KEF in patients with diabetes were reduced by 9.7% and 20.8%, respectively, in males, and by 11.6% and 23.0%, respectively, in females compared to the values in healthy control subjects. CONCLUSION: KEF and %KEF in patients with type 2 diabetes without diabetic polyneuropathy may reduce by approximately 10% and 20%, respectively, compared to these values in healthy control subjects. This study provides reference values for isometric KEF with respect to sex in a population covering a wide age range.
RESUMEN
Distal hereditary motor neuropathies (dHMNs) comprise a group of clinically and genetically heterogeneous inherited lower motor neuron syndromes mainly characterized by a distal-predominant pattern of progressive muscle atrophy, weakness and hyporeflexia, without sensory dysfunction. Although at least 21 causative genes for dHMN have been reported, mutational scanning of these genes often fails to identify the causative variants in dHMN cohorts, suggesting that additional causative genes remain to be identified. We studied a four-generation pedigree of a Japanese family with autosomal dominant dHMN to provide insight into the pathogenetic basis of the disease. Neurological examinations were performed on all six family members enrolled in this study. Whole-exome sequencing (WES) was used to identify the causative gene for dHMN. The clinical features of the patients included muscle weakness with distal extensor dominancy in the lower extremities, accompanied by facial and neck flexor muscle impairment, no sensory involvement, and areflexia. Nerve conduction studies demonstrated axonal changes mainly in the peroneal nerve. WES combined with rigorous filtering revealed three missense variants (NM_001083964: c.851Gâ¯>â¯A [p.Arg284His] in TDRKH, NM_002858: c.1654Gâ¯>â¯T [p.Gly552Cys] in ABCD3, NM_001005164: c.898Aâ¯>â¯T [p.Ile300Phe], in OR52E2). The variant in TDRKH is located in a conserved region of the tudor domain which is also present in the survival of motor neuron (SMN) protein, encoded by the SMN1 gene. Therefore, we concluded the variant in TDRKH is likely to be responsible for dHMN in our pedigree.

OBJECTIVE: This study investigated the factors affecting walking speed in schizophrenia patients who were inpatients at a psychiatric hospital. METHODS: The study subjects were 37 patients with schizophrenia who were hospitalized in a psychiatric hospital. The measured assessment items included age, duration of hospitalization, duration of disease, muscle strength (30-s chair stand test), balance ability (one-leg standing time with eyes open/closed, Functional Reach Test, and Timed Up & Go Test), flexibility (long sitting position toe-touching distance), walking speed (10-m maximum walking speed), and the antipsychotic drug intake. RESULTS: The walking speed was found to be correlated with the results of the 30-s chair stand test, the one-leg standing time with eyes open, the one-leg standing time with eyes closed, and the Timed Up & Go Test. Stepwise multiple regression analysis revealed that only the Timed Up & Go Test results affected walking speed. CONCLUSION: In schizophrenia patients, walking speed is influenced by balance and lower-limb muscle force, just as it is for patients without mental diseases. In schizophrenia patients, the dynamic balance ability has a strong influence on the walking speed.
RESUMEN
The purpose of this study was to summarize the approaches to behavior modification for exercise from the viewpoint of preventive medicine. Articles were searched according to the particular field of preventive medicine, i.e., primary prevention, secondary prevention, tertiary prevention, and other fields of prevention. In the field of primary prevention for elderly people living at home, many fall prevention programs were found to have been carried out. In these studies, various programs were found to be effective if the exercise proved to be sufficient. Although some approaches were observed to be based on the productive aging theory and social capital, the number of such studies was small. In the field of secondary prevention, illness and functional disorders are prevented from becoming worse. It is therefore important for each individual to exercise by himself/herself and also acquire sufficient self-monitoring skills. Social capital is useful for learning good exercise habits. In the field of tertiary prevention, although exercise therapy is effective for improving physical functions and preventing disease recurrence in patients with chronic disease, some patients nevertheless find it difficult to continue such an exercise therapy. The approaches to behavior modification were extremely effective for patients with chronic disease. In other fields of preventive medicine, daily exercises such stair climbing are effective methods for reducing the risk of chronic disease and such a behavior modification may lead to a considerable public health gain. In the future, further studies with a many lines of evidence should be performed, and approaches based on behavioral science should be established.

AIMS/INTRODUCTION: The present study elucidated the effect of diabetic polyneuropathy (DPN) on lower extremity strength in a wide age range of type 2 diabetes patients. MATERIALS AND METHODS: Participants (n = 1,442) were divided into three age groups (30-49 years, 50-69 years and 70-87 years), and comparisons were made separately for each sex. Lower extremity strength was measured in terms of knee extension force (KEF) with a hand-held dynamometer. KEF was compared according to the presence or absence of DPN. Furthermore, the effect of DPN on KEF with other diabetic complications (diabetic retinopathy and diabetic nephropathy), diabetes status (diabetes duration and glycated hemoglobin) and habitual behavior (regular exercise, smoking and drinking behaviors) as explanatory variables was analyzed using multiple regression analysis in several models. RESULTS: The frequency of DPN differed among age groups, ranging from 14.3 to 49.6%, and increasing with age. There was no significant difference in KEF between patients aged 30-49 years with and without DPN. However, among both men and women aged 50-69 years and 70-87 years, patients with DPN showed significantly diminished KEF (11.0-12.9% and 11.9-16.6%, respectively) compared with those without DPN (P < 0.01-0.001). In women aged 50-69 years and 70-87 years, and in men aged 50-69 years, DPN was a significant explanatory variable for KEF in all multiple regression analysis models. CONCLUSION: DPN might reinforce a KEF decline in middle-aged and elderly type 2 diabetes patients.
