Self-Rated Activity Levels and Longevity: Evidence from a 20 Year Longitudinal Study

A 2-year longitudinal study of three tree fruit packinghouses was conducted to determine the prevalence and distribution of Listeria monocytogenes. Samples were collected from 40 standardized non-food-contact surface locations six different times over two 11-month production seasons. Of the 1,437 samples collected, the overall prevalence of L. monocytogenes over the course of the study was 17.5%. Overall prevalence did not differ significantly (p > 0.05) between each year. However, values varied significantly (p ≤ 0.05) within each production season following packing activity levels; increasing in the fall, peaking in early winter, and then decreasing through spring. L. monocytogenes was most often found in the packing line areas, where moisture and fruit debris were commonly observed and less often in dry cold storage and packaging areas. Persistent contamination was attributed to the inability of water drainage systems to prevent moisture accumulation on floors and equipment during peak production times and uncontrolled employee and equipment traffic throughout the facility. This is the first multiyear longitudinal surveillance study to compare L. monocytogenes prevalence at standardized sample sites common to multiple tree fruit packinghouses. Recommendations based on our results will help packinghouse operators to identify critical areas for inclusion in their L. monocytogenes environmental monitoring programs.

Abstract BackgroundMotor imagery (MI) has been successfully applied in neurological rehabilitation. Little is known about the spontaneous selection of the MI perspectives in patients with sensorimotor impairments. What MI perspective is selected: internal (first- person view), or external (third-person view)? The aim was to evaluate the MI perspective preference in patients after stroke (STR), with Multiple Sclerosis (MS) or Parkinson’s disease (PD).MethodsIn a longitudinal study including four measurement sessions over two weeks, MI ability and MI perspective preference in both visual and kinaesthetic imagery modalities were assessed using the Kinaesthetic and Visual Imagery Questionnaire including 20 items (KVIQ-20), mental rotation, and mental chronometry. Additionally, patients' activity level was assessed. Descriptive statistical analyses were performed regarding different age- (≤44, 45-63, 64≤) and activity levels (inactive, partially active, active), and KVIQ-20 movement classifications (axial, proximal, distal, upper and lower limb).ResultsIn total, 55 in- and outpatients (25 SRT, 25 MS, 5 PD; 25 females; mean age 58±14 years) were included. At the first measurement session, the mean mental rotation score was 27±4.1 out of 32. For mental chronometry, a congruency ratio of 1.0±0.3 was determined. The KVIQ-20 scores for the visual and kinaesthetic subscales were 62.4±16.2 and 58.2±17.2. The internal MI perspective was favoured in 66.5% on the visual subscale and in 72.7% on the kinaesthetic subscale. The external perspective was preferred in 30.3% on the visual subscale and in 26.5% on the kinaesthetic subscale. Over the four measurement sessions, patients became more consistent in their MI perspective selection. MI perspective changes occurred mainly during imagination of shoulder, arm and neck movements. During imagination of foot and finger movements their MI perspective was more constant. Results showed a tendency to use an external perspective in patients older than 64 years and in patients with a descreasing physical activity level. Axial and proximal movements were commonly imagined using the external perspective. ConclusionIt is recommended to evaluate the spontaneous MI perspective selection to design patient-specific MI training interventions. Distal movements (foot, finger) may be an indicator when evaluating the consistency of the MI perspective in patients with sensorimotor impairments.

Sectional Analysis

BackgroundPhysical inactivity has been linked to headache disorders, but data regarding the current recommended leisure-time (LTPA) and commuting physical activity (CPA) levels is unknown.ObjectiveTo test the associations between headache disorders (definite and probable migraine tension type headache-TTH) and physical inactivity in these domains (LTPA and CPA) in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).MethodsIn a cross-sectional analysis, logistic regression models computed the odds ratio (OR) for the relationship between headache disorders and physical activity (LTPA and CPA) in the following levels: “active” (Reference), “insuciently active”, and “inactive”. The full models were controlled for the effects of sociodemographic data, cardiovascular risk profile, and use of headache medication (migraine prophylaxis)ResultsOf 15,0105 participants, 14,847 (45.6 % of men and 54.4 % women) responded the baseline interviews regarding physical activity levels and headache disorders. Overall, most significant physical inactivity was observed in LTPA domain for definite migraine [OR: 1.32 (1.10-1.57)] and probable migraine [OR: 1.33 (1.17-1.50)]. Similar findings were replicated by sex. Physical inactivity (LTPA) was positively associated with definite migraine in women [OR: 1.29 (1.04-1.59)], probable migraine in both men [OR: 1.40 (1.15-1.69)] and women [OR: 1.29 (1.04-1.59)]. Physical inactivity in CPA domain was associated to increased OR for probable TTH in men [OR: 1.33 (1.01-1.75)], while CPA was inversely associated to definite migraine [OR: 0.79 (0.64-0.98)] and probable migraine [OR: 0.80 (0.67-0.96)] in women. Considering all headaches, unmet vigorous physical activity levels were associated to increased OR for definite migraine [OR: 1.36 (1.13-1.65)] and probable migraine [OR: 1.37 (1.20-1.57)]. Finally, we found higher odds for daily headaches among LTPA-inactive [OR: 1.73 (1.20-2.49)] and CPA-insufficiently active [ OR: 1.36 (1.04-1.79)] participants.ConclusionPhysical inactivity is associated with headache disorders in the ELSA-Brasil study, with distinct associations regarding headache subtype, sex, physical activity domain and intensity, and headache frequency.

Background: Emerging evidence suggests that Indigenous children have higher physical activity levels that non-Indigenous children, yet little is known of the factors that influence these levels or how they may be optimized. This study examines correlates of achieving ≥1 hour/day of physical activity among Indigenous Australian children aged 8–13 years. Methods: Data were collected through parental self-report in the Longitudinal Study of Indigenous Children. Proportions of children achieving ≥1 hour/day physical activity, approximating the Australian aerobic physical activity recommendations, were calculated, and associations with sociodemographic, family composition, and movement-related factors were quantified using multiple logistic regression analyses. Results: Half of the 1233 children achieved ≥1 hour/day physical activity. Children from families with low parental education and unemployment, remote residence, low socioeconomic status, and without a father in the household were more likely to meet the recommendations. Achieving ≥1 hour/day of physical activity was also associated with low levels of playing electronic games and total screen time. Conclusions: Sociodemographic correlates of physical activity among Indigenous Australian children run counter to those typically found in non-Indigenous Australian children. Further longitudinal examination of the predictors of these associations would provide a greater understanding of Indigenous physical activity determinants, to inform strategies to facilitate participation.

Physical Activity Levels

According to Bandura’s social-cognitive theory, perceptions of somatic and affective barriers are sources of self-efficacy. This longitudinal study compares general indicators of health barriers with measures of perceived somatic and affective barriers to predict self-efficacy and accelerometer-assessed physical activity in a subsample of n = 153 (selected at random from N = 310) community-dwelling German older adults. Perceived somatic and affective barriers longitudinally predicted physical activity mediated by self-efficacy, whereas general health barriers did not. Perceived health barriers to physical activity might be more important than more objective health barriers for older adults’ physical activity levels.

ObjectivesTo assess whether educational differentials in three key physical activity (PA) domains vary by age, sex and ethnicity.DesignNational cross-sectional survey.SettingUK.ParticipantsAltogether 40 270 participants, aged 20 years and over, from the UK Household Longitudinal Study with information on education, PA and demographics collected in 2013–2015.Outcome measuresParticipation in active travel (AT), occupational activity (OA) and leisure time physical activity (LTPA) at the time of assessment.ResultsLower educational attainment was associated with higher AT and OA, but lower weekly LTPA activity; these associations were modified by sex, ethnicity and age. Education-related differences in AT were larger for women—the difference in predicted probability of activity between the highest and the lowest education groups was −10% in women (95% CI: −11.9% to 7.9%) and −3% in men (−4.8% to –0.4%). Education-related differences in OA were larger among men −35% (-36.9% to –32.4%) than women −17% (-19.4% to –15.0%). Finally, education-related differences in moderate-to-vigorous LTPA varied by ethnicity; for example, differences were 17% (16.2% to 18.7%) for white individuals compared with 6% (0.6% to 11.6%) for black individuals.ConclusionsEducational differences in PA vary by domain and are modified by age, sex and ethnicity. A better understanding of physically inactive subgroups may aid development of interventions to both increase activity levels and reduce health inequalities.

Background: In the preliminary results of a longitudinal study, we gathered baseline insights into students’ sleeping habits, activity levels and anxiety. The results showed that the seventh grade (now eighth grade) students reported mild anxiety, played sports non-competitively and underslept according to the National Sleep Foundation (NSF). In the second year of this study, we continue to look at the trends of sleep, athletic performance and emotional wellness. Methods: 40 eight grade students were administered an ActiGraph watch to assess sleep patterns. Students completed a background survey to obtain information regarding sports participation and subjective injury reports. Students completed the Beck Youth Anxiety Inventory (BYAI) to assess anxiety. Actigraph data was reviewed with a board certified sleep pulmonologist. Results: 16 males and 24 females wore the watch for 5 school nights. Average age of patients was 13 years (range: 13 to 14). 200 nights of nocturnal sleep were analyzed with total sleep time (TST) averaging: 6.2 hours (370 minutes) (range: 216 to 448 minutes). Females averaged 6 hours (368 minutes) and males averaged 6.25 hours (375 minutes) (p=0.62). Out of the 40 students that wore the watch, 78% (31/40) completed the background survey regarding sports participation. 78% (24/31) reported playing a sport and on average spend 7 hours a week playing (range: 1 to 30 hours). 78% (24/31) also participate in an organized or recreational sport and on average started competitive sports at the age of 6 years (range: 3 to 12 years). 46% (11/24) of students reported injuries that removed them from their sport during the school year (range: 1 to 4 injuries). On the BYAI (n=32), scores were significantly higher this year with a mean score of 16 (moderate anxiety) compared to last year (mean=12, p=0.01). Females scored significantly higher (p=0.04) on the BYAI (mean=18, n=20) than males (mean=12, n=12). Patients that also reported higher anxiety received significantly less sleep (p=0.01, r=-0.46). Conclusion: In the second year of our longitudinal study, our results show that students continue to sleep below the recommendation of the NSF (9 to 11 hours, 546 to 660 minutes) and select students are starting to specialize in sports. However, anxiety compared to last year was significantly higher. As they transition from middle school to high school, we expect to see students undergo personal development, commit to one sport and have a more rigorous school schedule that will continue to affect sleep and emotional wellness.
