Social Networks and Sugar-Sweetened Beverage Consumption in a Pediatric Urban Academic Practice.

Increased sugar-sweetened beverage (SSB) consumption is linked to childhood obesity. The risk of increased SSB consumption is multifactorial. Limited studies have examined children's SSB consumption and social networks. In order to examine the association between SSB consumption and SSB preferences of a child's social network, a cross-sectional survey was administered to patients aged 8-17 years from June to September 2016. In a questionnaire, subjects completed a beverage consumption recall, identified people important to them along with each person's favorite beverage, and answered questions about habits, environment, and attitudes. Subjects with higher SSB consumption (>16 fl oz) were compared to subjects with lower SSB consumption (≤16 fl oz). 202 surveyed: 55% female, 53% Hispanic, 45% Black, 28% overweight or obese. Children drank an average of 3 cups/day of SSBs, range of 0-15 cups/day. Social networks included caregiver, relative, and friend. Subjects with higher SSB consumption (n = 96) were compared to those with lower SSB consumption (n = 106). We found children with higher SSB consumption had higher odds of reporting a higher number of people in their immediate social networks who prefer SSB, adjusted for habits, environment, and attitudes (aOR 1.41; 95% CI: 1.02-1.99; p < 0.05). Children are more likely to have higher SSB consumption if they list people in their immediate social network who prefer SSB as their favorite drink. Further research is required to explore the influence of social networks on health behaviors of children.

Urinary levels of phthalate metabolites and their association with lifestyle behaviors in Chinese adolescents and young adults.

BACKGROUND: Adolescence and young adulthood are critical periods of human growth and development. Phthalates are environmental endocrine disruptors, and their health hazards in adolescents and young adults cannot be ignored. This study was undertaken to assess phthalate exposure and determine the associations between lifestyle behaviors and phthalate metabolite levels in Chinese adolescents and young adults. METHODS: Four hundred and seventy-eight adolescents and young adults aged 16-20 years were included in this study. The levels of mono-ethyl phthalate (MEP), mono-butyl phthalate (MBP), mono-(2-ethylhexyl) phthalate (MEHP), mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP), mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP), mono-(2-ethyl-5-carboxypentyl) phthalate (MECPP) and mono-(2-carboxmethyl)-hexyl phthalate (MCMHP) in the subjects' urine were measured by high-performance liquid chromatography-tandem mass spectrometry. The estimated daily intake (EDI) and hazard index (HI) of phthalates were calculated based on urinary metabolite levels. Relevant information on the subjects was collected via questionnaires. The associations between phthalate metabolite levels and lifestyle behaviors were examined using the independent-sample t-test, Mann-Whitney test and multiple linear regression. RESULTS: In this study, the detection rates of all seven metabolites were >98%. The highest median metabolite concentration was MBP, which was 43.00 µg/L (33.11 µg/g creatinine). The highest median EDI was for di-(2-ethylhexyl) phthalate (DEHP), which was 2.40 µg/kg-bw/day (volume-based) and 1.51 µg/kg-bw/day (creatinine-based). 2.7% (volume-based) and 1.0% (creatinine-based) of the subjects showed excessive HITDI (HI of the tolerable daily intake) values, which indicated the cumulative risk of anti-androgenic effects. Furthermore, factors significantly associated with phthalate metabolite levels included the use of plastic food packages (DEHP metabolites), physical exercise (MEOHP), the frequency of fast food consumption (MBP), and the frequency of skin care cosmetics and color cosmetics use (MEP). CONCLUSION: Our results suggest that Chinese adolescents and young adults are widely exposed to phthalates and their metabolite levels are influenced by lifestyle behaviors.

The association of medications with sedative properties with oral health behaviour in community-dwelling older people.

OBJECTIVES: The objective of this study was to determine whether drugs with sedative properties are related to oral health behaviour-such as frequency of toothbrushing, using toothpaste and dental visits-and oral hygiene, measured by the number of teeth with dental plaque, among community-dwelling older people. METHODS: The study population consisted of 159 community-dwelling, dentate, non-smoking, older people from the Oral Health GeMS study (Geriatric Multidisciplinary Strategy for the Good Care of Older People study). The data were collected by interviews and clinical examinations during 2004-2005. Sedative properties of drugs were assessed using the sedative load (SL) model. Logistic and Poisson regression models were used to estimate odds ratios/relative risks (OR/RR) and 95% confidence intervals (CI). RESULTS: After adjusting for confounding factors, SL associated with infrequent toothbrushing (OR 1.72, CI: 0.61-4.89), toothpaste use less than twice a day (OR 3.34, CI: 1.39-8.12), non-regular dental visits (OR 2.28 CI: 0.91-5.30) and the number of teeth with dental plaque (RR 1.20 CI: 1.04-1.39) compared to participants without a SL. CONCLUSIONS: The results of this study suggest that use of drugs with sedative properties indicates poor oral health behaviour among older people.

The association between ambient fine particulate air pollution and physical activity: a cohort study of university students living in Beijing.

BACKGROUND: Air pollution has become a substantial environmental issue affecting human health and health-related behavior in China. Physical activity is widely accepted as a method to promote health and well-being and is potentially influenced by air pollution. Previous population-based studies have focused on the impact of air pollution on physical activity in the U.S. using a cross-sectional survey method; however, few have examined the impact on middle income countries such as China using follow-up data. The purpose of this study is to examine the impact of ambient fine particulate matter (PM2.5) air pollution on physical activity among freshmen students living in Beijing by use of follow-up data. METHODS: We conducted 4 follow-up health surveys on 3445 freshmen students from Tsinghua University from 2012 to 2013 and 2480 freshmen completed all 4 surveys. Linear individual fixed-effect regressions were performed based on repeated-measure physical activity-related health behaviors and ambient PM2.5 concentrations among the follow-up participants. RESULTS: An increase in ambient PM2.5 concentration by one standard deviation (44.72 µg/m3) was associated with a reduction in 22.32 weekly minutes of vigorous physical activity (95% confidence interval [CI] = 24.88-19.77), a reduction in 10.63 weekly minutes of moderate physical activity (95% CI = 14.61-6.64), a reduction in 32.45 weekly minutes of moderate to vigorous physical activity (MVPA) (95% CI = 37.63-27.28), and a reduction in 226.14 weekly physical activity MET-minute scores (95% CI = 256.06-196.21). The impact of ambient PM2.5 concentration on weekly total minutes of moderate physical activity tended to be greater among males than among females. CONCLUSIONS: Ambient PM2.5 air pollution significantly discouraged physical activity among Chinese freshmen students living in Beijing. Future studies are warranted to replicate study findings in other Chinese cities and universities, and policy interventions are urgently needed to reduce air pollution levels in China.

Health-related quality of life among veterans in addictions treatment: identifying behavioral targets for future intervention.

BACKGROUND: US veterans report lower health-related quality of life (HRQoL) relative to the general population. Identifying behavioral factors related to HRQoL that are malleable to change may inform interventions to improve well-being in this vulnerable group. PURPOSE: The current study sought to characterize HRQoL in a largely male sample of veterans in addictions treatment, both in relation to US norms and in association with five recommended health behavior practices: regularly exercising, managing stress, having good sleep hygiene, consuming fruits and vegetables, and being tobacco free. METHODS: We assessed HRQoL with 250 veterans in addictions treatment (96 % male, mean age 53, range 24-77) using scales from four validated measures. Data reduction methods identified two principal components reflecting physical and mental HRQoL. Model testing of HRQoL associations with health behaviors adjusted for relevant demographic and treatment-related covariates. RESULTS: Compared to US norms, the sample had lower HRQoL scores. Better psychological HRQoL was associated with higher subjective social standing, absence of pain or trauma, lower alcohol severity, and monotonically with the sum of health behaviors (all p < 0.05). Specifically, psychological HRQoL was associated with regular exercise, stress management, and sleep hygiene. Regular exercise also related to better physical HRQoL. The models explained >40 % of the variance in HRQoL. CONCLUSIONS: Exercise, sleep hygiene, and stress management are strongly associated with HRQoL among veterans in addictions treatment. Future research is needed to test the effect of interventions for improving well-being in this high-risk group.

The effects of substance use and physical activity on cognition: The impact of incongruent health behaviors.

BACKGROUND: Cognitive functioning refers to storage and manipulation of information and includes executive functioning (EF) and attention (ATT). While physical activity (PA) improves cognitive functioning, decrements are associated with frequent substance use. This study examined PA on cognitive functioning within the context of past-year substance use. METHODS: Using NESARC-III data (N = 36,309), cross-sectional analysis examined interactions between self-reported past-year PA and substance use in relation to cognitive functioning. RESULTS: As hypothesized, light-to-moderate, vigorous, and total PA conditional main effects were positively associated with both facets of cognition, while frequent substance use conditional main effects were negatively associated with ATT and EF. The positive association between PA and cognition was diminished by substance use. Frequent binge drinking, marijuana, cocaine, and opioid use weakened the impact of light-to-moderate PA on EF, and only frequent cocaine use lessened the relationship between vigorous PA on EF. When PA intensities were combined, frequent binge drinking and cocaine use weakened the PA and EF association. Infrequent stimulant use reduced the association between all levels of PA and ATT, while infrequent marijuana use unexpectedly enhanced the relation between vigorous PA and ATT. CONCLUSIONS: Overall, PA enhanced two facets of cognitive functioning across six substances. However, these benefits are reduced in the context of frequency of substance use. The positive association between light-to-moderate PA and EF appears to be more sensitive in the context of frequent substance use than vigorous PA. Implications for public health messaging and PA as cognitive remediation treatment for substance use disorders are discussed.

Antidepressant-induced reduction in betel-quid use in patients with depression: A pioneer clinical study.

Betel-quid is commonly used around the world and is listed as a Group I carcinogen. Prior research has suggested a possible association between antidepressants and betel-quid use. We aimed to clarify the effects of antidepressant therapy in betel-quid chewers in the population of patients with depression.We enrolled 204 patients with depressive disorders, collected their demographic information, and administered the Substance Use Severity Rating Scale for alcohol, cigarettes, and betel-quid and the Hamilton Depression Rating Scale. We compared betel-quid and non-betel-quid chewers and examined the effects of antidepressant therapy on betel-quid abstinence after previous exposure to betel-quid.Patients with depression were reported a higher prevalence of 26% betel-quid chewing habits and patients who chewed betel-quid showed more severe depressive symptoms. After antidepressant therapy, the addictiveness of betel-quid was significantly reduced by 4 times.This was a pioneering study showing that antidepressants could be a candidate for betel-quid cessation therapy. Future clinical trials are needed to verify their efficacy in reducing consumption for betel-quid addiction treatment.

Control of cardiovascular risk factors and health behaviors in patients post acute coronary syndromes eligible for protein convertase subtilisin/kexin-9 inhibitors.

BACKGROUND: We aimed to examine cardiovascular risk factors and health behaviors in patients with acute coronary syndromes (ACS) according to potential extension of eligibility criteria for protein convertase subtilisin/kexin-9 inhibitors (PCSK9i) to all patients with low-density lipoprotein cholesterol (LDL-c) equal or above 1.8 mmol/l. METHODS: In this prospective cross-sectional study, patients with ACS between 2009 and 2016 and with available LDL-c at one year were considered. We defined three mutually exclusive groups of patients according to eligibility for PCSK9i: "not eligible", "currently eligible", and "newly eligible". We explored the control of cardiovascular risk factors and health behaviors. RESULTS: Out of 3025 patients who had an ACS one year ago, 1071 (35.4%) were not eligible for PCSK9i, 415 (13.7%) were currently eligible, and 1539 (50.9%) were newly eligible. The proportion of patients with uncontrolled hypertension in the not eligible group was lower than in the group currently eligible (27.6% vs 33.6%, p = 0.02), but similar to the group newly eligible (27.6% vs 28.2%, p = 0.73). The proportion of smokers in the not eligible group was lower than in the group currently eligible (21.2% vs 28.0%, p = 0.02), but similar to the group newly eligible (21.2% vs 22.5%, p = 0.51). CONCLUSIONS: More than half of patients with ACS would be additionally eligible for PCSK9i if prescription is extended from current guidelines to all patients with LDL-c equal or above 1.8 mmol/l. Patients currently eligible for PCSK9i one year after an ACS had a worst control of cardiovascular risk factors than patients potentially newly eligible.
