Introduction. Physical activity (PA), sedentary behaviour (SB) and sleep collec-
tively affect mental and physical health of older adults. According to the novel
24-hour movement guidelines, older adults should engage in at least 150 min-
utes of moderate-to-vigorous PA per week, limit their sedentary time to 8
hours per day, and sleep between 7 and 8 hours per day. The aim of this study
was to explore adherence to the 24-hour movement guidelines in a sample of
Slovenian older adults, and to compare self-reported and device measured es-
timates of meeting the guidelines.
Methods. A convenience sample of generally healthy participants were recruit-
ed via Slovenian centres of daily activities for older adults. They were asked to
wear research grade activity monitor ActiGraph for 6 days continuously (day
and night), complete a sleep diary, and a web-based Daily activity behaviours
questionnaire (DABQ). Descriptive statistics were used to calculate the pro-
portion of participants meeting individual and overall (all 3) guidelines. Cohen’s
kappa was used to test the agreement between self-reported and device meas-
ured adherence to the guidelines. Sensitivity and specificity of self-reported ad-
herence, when compared with device measured, were also calculated.
Results. Thirty-one participants (72 ± 6 years, 16 females) provided at least 5
days of valid data from ActiGraph and completed DABQ. According to Acti-
Graph (and DABQ) data, PA, SB and sleep recommendation was met by 74
% (71 %), 13 % (71 %) and 45 % (55 %) of participants, respectively. Overall
24-hour movement guidelines were met only by 3 % and 32 % of participants
when estimated using ActiGraph and DABQ, respectively. Agreement on ad-
herence between the methods was moderate for the PA (77 %; κ = .433) and
sleep (71%; κ = .425) recommendations, and slight for the SB (42%; κ = .114)
recommendation. The sensitivity of DABQ as 83 %, 100 % and 79 %, and spec-
ificity was 63 %, 33 % and 65 %, for the PA, SB and sleep recommendation, re-
spectively.
Discussion and conclusions. DABQ and ActiGraph produced comparable esti-
mates on a group level for meeting PA and sleep recommendations, while sub-
stantial discrepancy could be observed for the SB recommendation. In line with
previous studies, older adults tended to underreport SB. Future studies using
DABQ in older adults should interpret SB metric cautiously. Agreement be-
tween DABQ and ActiGraph for adherence to PA and sleep recommendations
was moderate, indicating those metrics are accurate enough to be used as a
population-based screening tool and for PA research. Based on the ActiGraph
data, three-quarters of our sample met the PA recommendation, one-half met
the sleep recommendation, while only a few (13 %) met the SB recommenda-
tion. The overall 24-hour movement guidelines were met by a single participant
(3 %), which might indicate an opportunity for promotion of integrated move-
ment guidelines among Slovenian older adults.
