Vickey and Breslin's research (published on mHealth, November 2015 issue) that involved analyzing nearly 2 million fitness tweets revealed a low percentage of mobile fitness app users meeting the recommended physical activity level. This commentary explores contextual and psychological factors that may underlie the observed low physical activity levels among these mobile fitness app users. Much remains unknown about how best to leverage technologies and social media support to promote adherence to physical activity recommendations. With the use of innovative and validated content mining strategies and taking consideration of relevant contextual and psychological factors associated with tweeting, tweets on physical activity offer a valuable data source to help us better understand: How can we mobilize people to 'tweet the walk' and 'keep the walk'?

Background

Because prenatal counseling is associated with adherence to weight gain guidelines, we sought to identify patient-level characteristics associated with the receipt of counseling on weight gain, nutrition, and exercise during prenatal care.

Methods

We performed a secondary data analysis on a cohort of women enrolled in a prenatal counseling intervention study. We controlled for study group assignment (intervention versus usual care) as well as patient characteristics in a multivariable analysis. We performed three separate multivariable analyses for predictors of provider-patient discussions about (1) weight gain, (2) nutrition, and (3) exercise.

Results

The cohort consisted of 311 predominantly low-income prenatal patients receiving care at several sites in the San Francisco Bay Area. Prepregnancy body mass index, nutrition knowledge, maternal age, parity, and type of insurance were not significantly associated with receipt of counseling about weight gain, nutrition, and exercise. In the multivariable analysis, white women were significantly less likely to be counseled about nutrition than non-white women (p=0.02). Former smokers were more likely to receive counseling about nutrition and exercise than never smokers (p<0.05). More advanced gestational age was associated with a higher rate of counseling on weight gain (p=0.01).

Conclusions

Despite having the highest rates of excessive weight gain nationally, white women were the least likely to receive counseling about nutrition during pregnancy. Interventions that prompt clinicians and simplify counseling may improve counseling rates for all patients during prenatal care.

Introduction

Low socioeconomic status is associated with high rates of cigarette smoking, and socioeconomic differences in cigarette smoking tend to emerge during young adulthood. To further our understanding of socioeconomic differences in smoking among young adults, we examined correlates of smoking, with attention to multiple socioeconomic indicators that have not been examined in this population.

Methods

We analyzed data from the 2011-2012 California Health Interview Survey. The analytic sample consisted of young adults aged 18-30 years who were considered socioeconomically disadvantaged as measured by education and poverty. Logistic regression analyses were conducted to examine factors associated with smoking status in this group, and multinomial logistic regression analyses were conducted to examine correlates of smoking frequency.

Results

In this sample (N = 1,511; 48% female, 66% Hispanic/Latino, 18% non-Hispanic white), 39.7% reported experiencing food insecurity in the past year. Smoking prevalence was significantly higher among young adults who reported being food insecure (26.9%) than among those who reported being food secure (16.4%). Past-year food insecurity was significantly associated with current smoking, independent of sociodemographic characteristics and alcohol use. Specifically, food insecurity was significantly associated with daily but not nondaily smoking.

Conclusion

Socioeconomically disadvantaged young adults with food insecurity may be considered a high-risk group with respect to cigarette smoking. Efforts to reduce tobacco-related health disparities should address diverse sources of socioeconomic influences, including experiences of food insecurity.

This study examined the moderating role of gender in the association between smoking status and depression in a nationwide convenience sample of Chinese American current, former, and never smokers (N=1393). Participants were recruited in smoker-supporter dyads. Multilevel modeling was used to take into account the dyadic nature of the data. Depressive symptoms were measured by a 10-item CES-D (Center of Epidemiological Studies-Depression Scale). Results showed significant effects of smoking status by gender interaction and smoking status on depression after adjusting for acculturation and social support. Among Chinese females, current smokers reported elevated depression level than both former and never smokers. Among Chinese males, current smokers reported more depressive symptoms when compared to former smokers only. Chinese females reported higher depression level than males among current smokers; no gender difference in depression was observed among former or never smokers. The association between smoking and depression is moderated by gender among Chinese Americans where substantial gender difference in smoking prevalence exists. Findings highlight the importance of addressing depression in treating tobacco use among Chinese American smokers, especially among females.

Objective

This study examined the use of a Video Doctor plus provider cueing to promote provider advice and smoking cessation outcomes in pregnancy.

Design

A randomized clinical trial was conducted from 2006 to 2008.

Setting

Five community prenatal clinics in the San Francisco Bay Area of the United States.

Participants

A total of 410 pregnant patients completed screening for behavioral risks including tobacco use in the past 30 days. Pregnant smokers (n = 42) were randomized regardless of their intention to quit smoking.

Methods

Participants were assigned to either usual care or intervention. Intervention participants received 15-minute Video Doctor sessions plus provider cueing, at baseline and one month, prior to their routine prenatal visit. The Video Doctor delivered interactive tailored messages, an educational worksheet for participants, and a cueing sheet for providers.

Main outcome measures

Receipt of advice from the provider and 30-day smoking abstinence, both by self-report.

Results

Intervention participants were more likely to receive provider advice on tobacco use at both prenatal visits during the intervention period (60.9 vs. 15.8%, p = 0.003). The intervention yielded a significantly greater decrease in the number of days smoked and in cigarettes smoked per day. The 30-day abstinence rate at two months post baseline was 2.5 times greater in the intervention group; the difference was not significant (26.1 vs. 10.5%, p = 0.12).

Conclusions

The Video Doctor plus provider cueing is an efficacious adjunct to routine prenatal care by promoting provider advice and smoking reduction among pregnant smokers.

Purpose

To examine how food insecurity and psychological distress interact in its association with smoking and to explore how food insecurity and psychological distress are associated with quitting smoking using quit ratio estimates.

Design

Cross-sectional study.

Setting

Data from the 2015 California Health Interview Survey.

Participants

A total of 3007 lower income adults who have ever smoked.

Measures

Ever smoking was defined as smoking 100+ cigarettes in the entire lifetime, with current smoking defined as smoking "every day" or "some days" and former smoking defined as smoking "not at all." Psychological distress and food insecurity were measured by the 6-item K6 Psychological Distress Scale and the 6-item Food Security Survey Short Form, respectively.

Analysis

Multiple logistic regression analysis was used to examine correlates of smoking status. Quit ratios (percentage of ever smokers who have quit) were calculated across study variables.

Results

Reporting food insecurity with psychological distress was independently associated with lower odds of being a former smoker, compared to reporting food security without psychological distress. The quit ratio was lower among ever smokers reporting food insecurity with distress (41%) compared to ever smokers reporting food security without distress (63%).

Conclusions

Specific conditions of impoverishment, such as food insecurity, interact with psychological distress in its association with continued smoking. Interventions to reduce socioeconomic disparities in smoking should consider the interacting role of food insecurity and psychological distress.

Purpose

This article describes strategies for recruiting and retaining Chinese elders in a longitudinal research study related to hypertension management.

Design

Chinese participants were recruited for a pilot, longitudinal intervention study. The information presented represents observations on both the recruitment process and participant retention.

Results

Recruiting via convenience sampling, offering frequent incentives, and having culturally competent research staff were important in this study with Chinese elders as participants. Among the various approaches used, the highest recruitment rate (50% [11/22]) was obtained from personal referrals with a retention rate of 91% (20/22) over a 6-month intervention period.

Conclusion/practice implication

Personal referral is the best approach for recruiting Chinese elders in the study. In addition, frequent incentives and reminder calls are helpful in retaining participants.

Purpose

To report the effectiveness of a prenatal intervention and to provide evidence that prenatal visits provide an opportune time for health assessment and counseling with abused women.

Methods

Fifty ethnically diverse pregnant women who presented for routine prenatal care and who also reported being at risk for intimate partner violence (IPV) were recruited to the study. Participants were assigned to either usual care or the Video Doctor plus Provider Cueing intervention. At baseline and 1 month later at another routine prenatal visit, intervention group participants received a 15-minute Video Doctor assessment and interactive tailored counseling. Their providers received a printed Cue Sheet alert and suggested counseling statements.

Main findings

Participants in the intervention group were significantly more likely to report provider-patient discussions of IPV compared with participants receiving usual care at baseline (81.8% vs. 16.7%; p < .001) and at the 1-month follow-up (70.0% vs. 23.5%; p = .005). Summing the number of patient-provider discussions across the two visits at baseline and 1 month later, intervention participants were significantly more likely to have IPV risk discussion with their providers at one or both visits (90.0% vs. 23.6%; p < .001) compared with the participants who received usual care. When specifically asked about the helpfulness of these IPV-related discussions, 20 out of 22 (90.9%) participants rated the discussion as helpful or very helpful at baseline and all 18 (100%) participants rated the discussion as helpful or very helpful at the 1-month follow-up.

Conclusion

Video Doctor plus Provider Cueing intervention significantly increases the likelihood of provider-patient IPV discussion with pregnant women with a history of abuse.

Different language versions of the Fagerstrom Test for Nicotine Dependence (FTND) have been developed, but no studies have evaluated measurement equivalence between the respective non-English and English versions. We investigated differential item functioning (DIF) of the English and Chinese versions using a multidimensional item response theory approach. A community sample of 409 American smokers completed the English version (n=241) and the Chinese version (n=168). Results indicated two correlated dimensions (morning and daytime nicotine dependence) of the FTND and one item (difficult to refrain) showing significant large DIF, suggesting respondents using the Chinese version were more likely to endorse this item and report more difficulty to refrain from smoking at various public places even after controlling for the nicotine dependence level. However, the impact of this DIF item was found negligible on the scale level, suggesting the acceptability of conducting scale-level analysis using both language versions. Further analysis revealed that the reliabilities of two dimensions did not meet the commonly accepted standard. Suggestions were made to improve scale reliabilities of the FTND.

In the U.S., cigarette smoking is increasingly concentrated in disadvantaged and vulnerable populations, such as populations with lower income and with mental health needs. Food insecurity is linked with psychological distress and is an independent risk factor for smoking. We prospectively examined how cigarette smoking, food insecurity, and psychological distress operate as risk factors for one another in a 2-year longitudinal analysis of U.S. adults from the 2015 and 2017 Panel Study of Income Dynamics, a nationally representative household survey (N = 7946). Using cross-lagged panel analysis, cross-lagged regression coefficients were estimated simultaneously with direct-effect paths, controlling for covariates. Results showed significant bidirectional associations between smoking and food insecurity: 2015 smoking predicted 2017 food insecurity, and 2015 food insecurity predicted 2017 smoking. Food insecurity and psychological distress also had significant bidirectional associations. However, the association between smoking and psychological distress was unidirectional: 2015 psychological distress predicted 2017 smoking, but not vice versa. The findings suggest a cyclical possibility that smoking exacerbates food insecurity, food insecurity exacerbates psychological distress, and psychological distress exacerbates smoking. There is a need to replicate with more timepoints, but our results highlight the importance of examining the overlapping health burdens of smoking, food insecurity, and psychological distress.
