Abstract This study aims to explore the effects of physical activity and sedentary behaviour on the decline of cognitive ability among the elderly. It uses objective measures to compensate for the limitations of self-reported physical activity. A cross-sectional survey of 308 people aged over 60 in Nanjing, China, was conducted. Physical activity was measured using the ActiGraph GT3X+, and cognitive function was measured using the Montreal Cognitive Assessment (MoCA). The overall participant model, adjusted for age, BMI, education, and monthly average income found that light physical activity (LPA; β=0.006, p<0.01), moderate-vigorous physical activity (MVPA; β=0.068, p<0.001), and total physical activity (β=0.006, p<0.01) had a significant linear relationship with cognitive ability, while sedentary time (SED) did not (β=-0.020, p＞0.05). Further, LPA only affects the cognitive ability of elderly females (β=0.006, p<0.05). In addition, there was an inverted ‘U’ dose-response relationship between MVPA and cognitive ability. Dose-effect relationship models found that MVPA in the 22.13 min·day–1～38.79 min·day–1 range affected cognitive ability most beneficially. The beta coefficient was higher than the other three groups (β=0.091, p<0.05). In conclusion, while physical activity can significantly improve cognitive ability among the elderly, sedentary behaviour has no significant effect on it.

Abstract Background: This study explored the effects of physical activity and sedentary behaviour on the decline of cognitive ability among the elderly. To compensate for the limitations of self-reported physical activity, objective measures were used. Methods: A cross-sectional survey of 308 aged people mean 68.66±5.377 years, in Nanjing, China, was conducted. Physical activity was measured using the ActiGraph GT3X+, and cognitive function was measured using the Montreal Cognitive Assessment. Results: The overall participant model, adjusted for age, BMI, education, and monthly average income, found that light physical activity (β=0.006, p<0.01), moderate-vigorous physical activity (β=0.068, p<0.001), and total physical activity (β=0.006, p<0.01) had a significant linear relationship with cognitive ability, while sedentary time did not (β=-0.020, p＞0.05). Further, light physical activity only affects the cognitive ability of elderly females (β=0.006, p<0.05). There was an inverted ‘U’ association between moderate-vigorous physical activity and cognitive ability. The association models found that moderate-vigorous physical activity in the 22.13 min·day–1～38.79 min·day–1 range affected cognitive ability most beneficially, with the highest beta coefficient among all groups (β=0.091, p<0.05). Conclusions: While physical activity can significantly improve cognitive ability among the elderly, sedentary behaviour is associated with decreased cognitive function across genders.

ABSTRACT Physical activity is a factor that can inhibit cognitive decrease in the elderly. One of the preventive actions that can be done by the elderly in slowing down the decrease of cognitive function is to increase physical activity. Physical activity is thought to stimulate nerve growth which might inhibit cognitive decrease in the elderly. When doing physical activity, the brain will be stimulated so that it will increase the Brain Derived Neurotropic Factor which plays a role in keeping nerve cells fit and healthy. Based on the explanation, the aim of this study was to identify the relationship between physical activity and cognitive function in the elderly. This study was a quantitative study with a categorical correlative analytic method. The study used cross sectional study design. The chi-square test and ordinal logistic regression test were used for data analysis. The results of this study stated that the overall physical activities which were exercise, mild activity, heavy activity, use of stairs and participate in social activities showed a significant relationship to cognitive function. Participating in social activities and mild activity were the most significant physical activities that showed relationship to cognitive function, with p-value = 0.001 < 0.05. In conclusion, the findings highlight that the choice of appropriate physical activity can help to maintain cognitive function in the elderly.

Abstract BackgroundAlthough many studies have reported the association between moderate-to-vigorous physical activity (MVPA), sedentary time (ST), and the built environment (BE) among older adults, little is known about these associations in the Chinese older adult population. The purpose of this study was to investigate how various factors in the built environment of Nanjing’s communities influence leisure moderate-to-vigorous physical activity and sedentary time among the elderly.MethodsA multilevel cross-sectional study was conducted from November 2016 to April 2017. Altogether, thirty neighborhoods were selected and 586 individuals aged 60 years or older living in the urban zone of NanJing in Southern China were surveyed. Physical activity was measured using Actigraph GT3 Accelerometer. Built environment variables were measured using ArcGIS software. A multivariate linear regression method was used to analyze the factors influencing leisure moderate-to-vigorous physical activity and sedentary time among the elderly.ResultsThe percentage of moderate-to-vigorous physical activity of urban elderly within a 1000-m distance reached 76.12%, indicating this zone as appropriate for the study of urban elderly moderate-to-vigorous physical activity. We found that land-use mix (β=8.800, p=0.001) and distance to fitness venue (β=-5.876, p=0.004) influenced moderate-to-vigorous physical activity. Population density (β=13.998, p=0.004) and land-use mix (β=-21.62, p=0.033) use influenced sedentary time.ConclusionsOur findings provide support for the association between the built environment and physical activity among the Chinese elderly. Some characteristics of the built environment including land-use mix and distance to fitness venue may affect MVPA, while other characteristics including population density and land-use mix may impact ST. In formulating urban planning policies, the above factors should be taken into account to promote physical activity in older people, encouraging them to modify their sedentary lifestyle and improving their overall health.

Peningkatan jumlah lansia setiap tahunnya harus dijadikan perhatian, akibat adanya peningkatan jumlah lansia masalah yang dihadapi akan menjadi semakin kompleks, salah satunya adalah masalah yang berkaitan dengan gejala penuaan. Menurunnya kapasitas intelektual berhubungan erat dengan fungsi kognitif pada lansia. Aktivitas fisik diidentifikasi sebagai salah satu faktor yang mempengaruhi fungsi kognitif. Aktivitas fisik bermanfaat untuk lansia sebagai pencegahan dan demensia. Penelitian ini merupakan penelitian analitik observasional dengan menggunakan pendekatan cross sectional. Penelitian dilakukan di yayasan sosial Panti Wredha Salib Putih Salatiga pada bulan Juni 2018. Populasi dalam penelitian ini adalah lansia yang berumur ?60 tahun. Subjek pada penelitian ini berjumlah 16 responden. Variabel independen dalam penelitian ini adalah aktivitas fisik yang dinilai dengan menggunakan instrument GPAQ. Sedangkan variabel dependen dalam penelitian ini adalah fungsi kognitif yang dinilai dengan instrument MMSE. Terdapat 4 orang (25%) yang masuk dalam kategori fungsi kognitif normal dengan kategori aktifitas fisik sedang 1 orang dan aktifitas berat 3 orang, kemudian yang termasuk dalam kategori gangguan fungsi kognitif ringan sebanyak 11 orang (68,75%), dengan kategori aktifitas fisik sedang 8 orang dan aktifitas ringan 3 orang. Sedangkan yang termasuk dalam kategori gangguan fungsi kognitif berat, terdapat 1 orang (6,25%) dengan kategori aktifitasnya ringan. Taraf signifikansi antar variabel tingkat aktifitas fisik dan fungsi kognitif pada lansia adalah p=0.007 atau p<0,05, sehingga dapat disimpulkan ada  hubungan antara tingkat aktifitas fisik dengan fungsi kognitif pada lansia.   Increasing the number of elderly people every year should be a concern, due to an increase in the number of elderly problems faced will become increasingly complex, one of which is a problem related to the symptoms of aging. Decreased intellectual capacity is closely related to cognitive function in the elderly. Physical activity is identified as one of the factors that influence cognitive function. Physical activity is beneficial for the elderly as prevention and dementia. This study was an observational analytic study using a cross sectional approach. The study was conducted at the social foundation nursing home in the white cross in June 2018. The population in this study was elderly aged ≥60 years. The subjects in this study were 16 respondents. The independent variable in this study is physical activity that is assessed using the GPAQ instrument. While the dependent variable in this study was cognitive function which was assessed by the MMSE instrument. There are 4 people (25%) who fall into the category of normal cognitive function with moderate physical activity categories 1 person and heavy activities 3 people, then those included in the category of mild cognitive function disorders are 11 people (68.75%), with the category of physical activity being 8 people and 3 light activities. While those included in the category of severe cognitive function disorders, there is 1 person (6.25%) with a mild activity category. The significance level between the level of physical activity and cognitive function in the elderly is p = 0.007 or p <0.05, so it can be concluded that there is a relationship between the level of physical activity and cognitive function in the elderly.
