The Physical Activity Guidelines for Americans, second edition, recommends older adults participate in ≥150 minutes per week of moderate-intensity equivalent aerobic activity and ≥2 days per week of muscle-strengthening activity. We estimated prevalence and trends of meeting the guidelines among US adults aged ≥65 years from 1998 to 2018. Using the 1998-2018 National Health Interview Survey, we estimated the prevalence of meeting aerobic, muscle-strengthening, and combined physical activity guidelines stratified by age group, sex, race and ethnicity, and education level. Within age groups, we calculated prevalence differences by sociodemographic categories. Prevalence of meeting each guideline increased for all age groups and most sociodemographic subgroups. The increased magnitude of meeting the combined guideline from 1998-2000 to 2016-2018 differed across levels of educational attainment for most age groups. Despite increasing over time, the prevalence among older adults of meeting physical activity guidelines remains low (range for combined guideline: 7.2%-17.2%).

In Chile, compliance with the Food-Based Dietary Guidelines (GABA) ensures an adequate and ba lanced diet.
OBJECTIVE: To determine compliance with five GABA recommendations and their asso ciations with anthropometric, lifestyle, and metabolic variables, in adolescents aged between 15 and 19 years who participated in the Chilean National Health Survey 2016-2017.
METHODS: Cross-sectional study including 355 adolescents. Participants were divided into four groups (fulfilled 0, 1, 2, or ≥ 3 recommendations) using five messages from the GABA (consumption of legumes, fish, dairy products, water, and fruits and vegetables). Associations between GABA and outcome variables (weight, body mass index, waist circumference, physical activity, sleep, and metabolic variables) were investigated using linear regression analyses adjusted by sociodemographic confounders.
RESULTS: 5.6% of the adolescents met three or more GABA recommendations. Of the recommendations mea sured, the consumption of water (85%) and legumes (78.7%) presented greater compliance, showing differences between women and men regarding the consumption of legumes (58.6% vs. 86.4%), wa ter (69.6% vs. 91%), and dairy products (92.9% vs. 39.1%). Adolescents with higher compliance with GABA had a better concentration of lower glycemia (p = 0.025). There were no other significant asso ciations between lifestyle and anthropometric measurements.
CONCLUSIONS: Adolescents who partici pated in this study presented difficulties in adhering to GABA recommendations, thus compromising the maintenance of healthy lifestyles.

There is a need for evidence-based guidelines for gamblers who wish to reduce their risk of harm by setting self-directed limits on their gambling. Recognizing this, the Canadian Low-Risk Gambling Guidelines were developed using data from 8 countries to establish the relationship between gambling behaviour and harm. The guidelines include recommended limits on gambling spending as a percentage of income, gambling frequency, and number of types of games played. However, the developers of the LRGG\'s did not include UK data in their analysis. This study analyzes data from Health Survey England to assess the applicability of the Canadian Low-Risk Gambling Guidelines to gamblers in England. Using HSE data from 2016 to 2018, we generated risk curves for the relationship between 2 dimensions of gambling behaviour-frequency of gambling sessions and number of types of games played-and gambling harm. We defined harm as a score of 1 or above on the Problem Gambling Severity Index. HSE does not include questions on gambling spending, therefore this was not assessed. The relationship observed between frequency and types of gambling and harm among HSE respondents was similar to the risk curves generated for the development of the Canadian LRGG\'s. Gamblers in England who gambled twice weekly or more, or who played 3 or more types of games, were significantly more likely to experience harm from gambling than those who gambled below these limits. The Canadian LRGG\'s may potentially be applied to gambling harm reduction efforts in England. More research is needed to determine the acceptability of these guidelines to people who gamble in England.

Parents often have concerns regarding anorexia in their children and visiting medical institutions for the intervention of it. This study aimed to investigate the clinical practice patterns of Korean medicine doctors (KMDs) for anorexia in children using a web-based survey. A link to the questionnaire was sent via email to all KMDs that were affiliated with the Association of Korean Medicine. The questionnaire covered items on the sociodemographic characteristics and clinical characteristics related to Korean medicine (KM), such as diagnosis, treatment, awareness, safety, and effectiveness. Of 23,910 KMDs, 384 agreed to participate and complete the questionnaire. Anorexia in children was diagnosed mainly by clinical features (36.4%) and the pattern identification (PI) theory of \'Qi, Blood, Fluid, Humor, and Organ system diagnoses\' (32.8%). The most frequently used PIs was \'spleen-stomach qi deficiency\' (38.6%), which was followed by \'spleen failure in transportation\' (23.3%), \'stomach yin deficiency\' (15.5%), and \'liver depression\' (14.2%). Herbal medicine (38.1%) was the primary KM treatment for anorexia, and the names of the most frequently prescribed herbal decoctions were Sogunjung-tang (16.5%), Hyangsayukgunja-tang (15.9%), and Bojungikgi-tang (13.9%). This study provides information on the existing clinical practice patterns of KMDs for anorexia in children. Based on this survey, the clinical practice guidelines will be developed.

To describe the prevalence of arterial hypertension according to sociodemographic characteristics in Brazil and to analyze the indicators related to access to health services and guidelines for controlling the disease in the country.
Cross-sectional descriptive study using the National Health Survey (PNS) conducted in 2019. The prevalence of hypertension was estimated with a 95% confidence interval, in addition to the proportions of hypertension indicators.
There were 88,531 respondents, of which 23.9% self-reported hypertension, more prevalent among females (26.4%) and the elderly (55.0%). Among those who self-reported hypertension, 57.8% reported medical attention in the last six months; most received guidance on self-care; 66.1% were seen in public health services; and 45.8%, in primary health care units.

The current UK physical activity guidelines recommend that adults aged 19 to 65 years perform activity to strengthen muscle and bone a minimum of twice weekly. The number of adults meeting strengthening activity guidelines is lower than for aerobic activity, but estimates vary between studies partly due to differences in how muscle-strengthening activity is defined. We aimed to provide estimates for strengthening activity prevalence in English adults based on a nationally representative sample of n = 253,423 18-65-year-olds. We attempted to quantify the variation in estimates attributable to differences in the way strengthening activity is defined. Finally, we aim to provide a brief descriptive epidemiology of the factors associated with strengthening activity. Adults met guidelines for aerobic activity if they reported the activity equivalent to >150 min/week moderate-intensity exercise. Respondents met strengthening guidelines if they reported at least two bouts per week of strengthening activity. We defined strengthening activity, first, according to criteria used in the Health Survey for England (HSE). Second, we counted bouts of strengthening activities for which we could find evidence of health-related benefits (Evidence). Third, we included bouts of strengthening activity as defined in current UK physical activity guidelines (Guideline). Two-thirds (67%) of adults met guidelines for aerobic activity (69% of men, 65% of women). Less than one-third (29% of men and 24% of women) met guidelines for the HSE definition of strengthening activity. Under the Evidence definition, 16% of men and 9% of women met strengthening guidelines. Using the most-stringent definition (Guideline) just 7.3% of men and 4.1% of women achieved the recommendations for strengthening activity. We found females and older adults (50-65 years) were less likely to meet guidelines for aerobic, strengthening, and combined aerobic plus strengthening activity. The prevalence of meeting activity guidelines was lower in adults from more deprived areas (compared with the least deprived); Adults with lower academic qualifications (Level 1) were less likely to meet activity guidelines than those educated to Level 4 (Degree Level) or higher. Having a limiting disability was associated with a lower prevalence of meeting activity guidelines. Associations between socio-demographic measures and the prevalence of adults meeting activity guidelines were stronger for strengthening activity than for aerobic 51(or combined aerobic plus strengthening) activity Compared with aerobic activity, fewer adults engage in strengthening activity regardless of how it is defined. The range in estimates for how many adults meet strengthening activity guidelines can be explained by variations in the definition of \'strengthening\' that are used and the specific sports or activities identified as strengthening exercise. When strengthening activity is included, the proportion of English adults meeting current physical activity guidelines could be as high as 1 in 3 but possibly as low as just 1 in 20. A harmonized definition of strengthening activity, that is aligned with physical activity guidelines, is required to provide realistic and comparable prevalence estimates.

The Canadian 24-Hour Movement Guidelines for Adults (18-64 years and 65 years or older) were launched in October 2020 and provide evidence-based recommendations for physical activity, sedentary behaviour and sleep. The purpose of this study was to examine whether meeting the 24-Hour Movement Guidelines overall, and different combinations of recommendations within the guidelines, was associated with health indicators in a representative sample of Canadian adults.
Participants were 8,297 adults aged 18 to 79 from cycles 1 to 3 of the Canadian Health Measures Survey. They were classified as meeting or not meeting each of the recommendations required for overall guideline adherence: moderate-to-vigorous physical activity (150 minutes or more per week), sedentary behaviour (8 hours or less per day or 9 hours or less per day of sedentary time, including 3 hours or less per day of recreational screen time) and sleep duration (7 to 9 hours per day for adults 18 to 64 years old, 7 to 8 hours per day for adults aged 65 years or older). A combination of self-reported and device-based measures were used. Indicators of adiposity (n=2), aerobic fitness (n=1) and cardiometabolic health (n=7) were measured.
A total of 19.1% of the sample met none of the recommendations, 43.9% met one of them, 29.8% met two and 7.1% met all three. Compared with meeting no recommendations, meeting one, two and all three recommendations was associated with better health for one, six and seven health indicators, respectively (p < 0.05). Compared with adults meeting two or fewer recommendations, those who met all three recommendations had more favourable body mass index; waist circumference; aerobic fitness scores; and triglyceride, insulin, C-reactive protein and serum glucose levels (p < 0.05).
These findings provide support for the 24-Hour Movement Guidelines and show that less than 1 in 10 Canadian adults are meeting all three of the healthy movement behaviour guidelines.

BACKGROUND: In 2017, the American College of Cardiology/American Heart Association revised guidelines for diagnosis and management of hypertension in adults. The regional impact of the updated guidelines on the prevalence of hypertension in India is unknown.
METHODS: Data from nationally representative Indian households were analyzed to estimate the regional prevalence of hypertension according to the old and the new guidelines in men (age 18-54 years) and women (age 18-49 years). The old guidelines defined hypertension as a systolic blood pressure of ≥140 mmHg or diastolic blood pressure of ≥90 mmHg or treatment. The new guidelines define hypertension as a systolic blood pressure of ≥130 mmHg or diastolic blood pressure of ≥80 mmHg or treatment. We calculated the increase in the prevalence of hypertension among the states and union territories of India (hereafter \"states\").
RESULTS: Among 679,712 participants (85.6% women), the median age was 31 years (interquartile range 24, 40) and was comparable among men and women (33 vs. 31 years, respectively). The overall weighted prevalence according to old and new guidelines was 18.5% (95% CI 18.2, 18.7) and 43.0% (95% CI 42.8, 43.3), respectively. There was a significant increase in hypertension prevalence, both among men and women, and across all regions. The northeast region of the country had the highest prevalence.
CONCLUSIONS: The overall prevalence of hypertension significantly increases with the new compared to the old guidelines, however, the regional heterogeneity of prevalence of hypertension is maintained.

BACKGROUND: Nigeria has unimpressive maternal and child health indicators. Compliance with the WHO guidelines on the minimum number of antenatal care (ANC) contacts could improve these indicators. We assessed the compliance with WHO recommended standards on ANC contacts in Nigeria and identify the associated factors.
METHODS: Nationally representative cross-sectional data during pregnancy of 21,785 most recent births within five years preceding the 2018 Nigeria Demographic Health Survey was used. The number of ANC contacts was categorised into \"None\", \"1-3\", \"4-7\" and \"8 or more\" contacts based on subsequent WHO guidelines. Descriptive statistics, bivariable and multivariable multinomial logistic regression was used at p = 0.05.
RESULTS: About 25 % of the women had no ANC contact, 58 % had at least 4 contacts while only 20 % had 8 or more ANC contacts. The highest rate of 8 or more ANC contacts was in Osun (80.2 %), Lagos (76.8 %), and Imo (72.0 %) while the lowest rates were in Kebbi (0.2 %), Zamfara (1.1 %) and Yobe (1.3 %). Respondents with higher education were twelve times (adjusted relative risk (aRR): 12.46, 95 % CI: 7.33-21.2), having secondary education was thrice (aRR: 2.91, 95 % CI: 2.35-3.60), and having primary education was twice (aRR: 2.17, 95 % CI: 1.77-2.66) more likely to make at least 8 contacts than those with no education. Respondents from households in the richest and middle wealth categories were 129 and 67 % more likely to make 8 or more ANC contacts compared to those from households in the lowest wealth category respectively. The likelihood of making 8 ANC contacts was 89 and 47 % higher among respondents from communities in the least and middle disadvantaged groups, respectively,  compared to the most disadvantaged group. Other significant variables were spouse education, health care decision making, media access, ethnicity, religion, and other community factors.
CONCLUSIONS: Compliance with WHO guidelines on the minimum number of ANC contacts in Nigeria is poor. Thus, Nigeria has a long walk to attaining sustainable development goal\'s targets on child and maternal health. We recommend that the maternal and child health programmers should review existing policies and develop new policies to adopt, implement and tackle the challenges of adherence to the WHO recommended minimum of 8 ANC contacts. Women\'s education, socioeconomic status and adequate mobilization of families should be prioritized. There is a need for urgent intervention to narrow the identified inequalities and substantial disparities in the characteristics of pregnant women across the regions and states.

Despite the 2016 German \"National Recommendations for Physical Activity and Physical Activity Promotion\" stating that adults (≥18 years) should engage in: [a] ≥150 minutes of aerobic moderate-to-vigorous-intensity physical activity/week (MVPA); and [b] ≥2 days/week of muscle-strengthening exercise (MSE), there is limited research on the descriptive epidemiology on the adherence to these guidelines among German adults. This study describes the prevalence and correlates of physical activity guideline adherence among a nationally representative sample of German adults. Data were drawn from the 2014 German Health Update survey, collected via a combination of web-based and mail surveys. Self-reported physical activity levels were assessed using the previously validated European Health Interview Survey Physical Activity Questionnaire. Weighted prevalence levels of the sample meeting the aerobic MVPA (≥150 minutes/week), MSE (≥2 times/week), and combined MVPA-MSE guidelines were calculated. Poisson regressions were used to assess prevalence ratios for physical activity guideline adherence categories across sociodemographic and lifestyle-related variables. Out of 24,016 participants (response rate = 27.6%), aged ≥ 18 years, 45.3% (95% CI: 44.5%-46.0%), 29.4% (95% CI: 28.7%-30.1%), and 22.6% (95% CI: 21.9%-23.2%) met the aerobic MVPA, MSE, and combined guidelines, respectively. Population sub-groups less likely to meet the combined guidelines included those with poor self-rated health, being unemployed, low socioeconomic status, being a current smoker, and those being overweight or obese. Since ~ 80% of German adults do not meet the nationally recommended combined aerobic MVPA-MSE physical activity guidelines, there is a necessity for large-scale public health interventions promoting both aerobic MVPA and MSE.
