Gender differences in diet and social media: An explorative study.

This study aimed to investigate the impact of social media on perceptions of food-related content. We asked participants a series of questions about their diet, attitudes, and social media use. We also manipulated food photos posted on Instagram to reveal varying degrees of information from the social media app (no Instagram information, icons visible, number of likes visible, or caption visible). Participants rated the foods in these photos based on how healthy they perceived them to be and how likely they were to eat them. We then used a 2X4 MANOVA to test whether healthy, unhealthy, and neutral foods were perceived differently between genders and conditions. Results showed no effect of condition, but indicated that men rated unhealthy foods as significantly healthier than women did. We also found that women's perceived healthiness ratings of healthy foods were positively correlated with ratings of how likely they were to eat them; in contrast, there were no relationships between perceived health and likelihood of eating any foods for men. Finally, results of our social media use questions indicated that Facebook was the most popular website used for finding recipes. These findings suggest that while we did not see any between-condition differences, social media may be a factor in what people eat. Furthermore, gender may be a key factor in this relationship.

Attenuating Physiological Arousal Through the Manipulation of Simple Hand Movements.

The current study tests whether manipulating simple motor movements can regulate one's physiological reactivity to negative images. Healthy college age participants were randomly assigned to no tapping, steady tapping, or slow tapping conditions and viewed two sets of 15 negative images from the international affective picture system. Participants viewed the first image set without manipulation. During the second image set, they were instructed to tap at a steady pace, a slow pace or not at all. Steady tapping suppressed the vagal component of the cardiovascular defense response, and produced a significant increase in respiration rate and skin conductance level (SCL). Slow tapping suppressed the sympathetic and enhanced the vagal components of the cardiovascular defensive response, and produced a decrease in heart rate, SCL and skin conductance responses to negative images. Results suggest that manipulating simple motor movements is an effective way to both up-regulate and more importantly, down-regulate one's physiological response to negative affective images. Manipulation of slow and simple motor movements may be an effective means to attenuate autonomic arousal.

Randomized trial of technology-assisted self-monitoring of blood glucose by low-income seniors: improved glycemic control in type 2 diabetes mellitus.

Self-monitoring of blood glucose (SMBG) has been recommended for people with type 2 diabetes mellitus. This trial tested an automated self-management monitor (ASMM) that reminds patients to perform SMBG, provides feedback on results of SMBG, and action tips for improved self-management. This delayed-start trial randomized participants to using the ASMM immediately (IG), or following a delay of 6 months (DG). Glycated hemoglobin (HgbA1c) level and survey data was collected at home visits every 3 months. 44 diabetic men and women, mean age 70, completed the 12-month trial. Baseline HgbA1c was 8.1 % ± 1.0, dropping to 7.3 ± 1.0 by 9 months, with a 3-month lag in the DG (F = 3.56, p = 0.004). Decrease in HgbA1c was significantly correlated to increased frequency of SMBG, R = 0.588, p < 0.01. Providing older diabetics with objective immediate contingent feedback resulted in more frequent SMBG that correlated with better glycemic control. This type of technology may provide real-time feedback not only to patient users, but to the health care system, allowing better integration of provider recommendations with patient-centered action.

Effects of cardiovascular arousal on emotional experience.

Studies of arousal and emotion show that generalized physiological arousal can enhance emotional experience for a range of different emotions. Other research shows that different emotions may be associated with specific patterns of physiological reactivity. Together these findings suggest that while nonspecific autonomic activation can be sufficient in the generation of emotion, specific patterns of reactivity may appear once the emotion is established. This study aimed to test this hypothesis by examining the effects of generalized arousal on emotional experience, as well as the physiological responses associated with positive and negative emotions. One hundred and nine participants either sat or stood during the viewing of positive and negative film clips while emotion ratings and cardiorespiratory measures were taken. Those who stood during the videos reported greater levels of emotion than those who sat, indicating that generalized arousal due to standing heightened emotional experience. In addition, participants exhibited greater high-frequency heart rate variability and lower respiration rate during the negative video than the positive video, indicating that physiological reactivity differed between the positive and negative emotions. These results suggest that while patterns of physiological reactivity may be specific to individual emotions, nonspecific arousal is sufficient to enhance diverse emotions.

Effects of self-affirmation on emotion and cardiovascular responses.

Self-affirmation is the act of focusing on important aspects of the self, such as personal values and characteristics. We used a within-participants design (N = 125) to examine cardiovascular reactivity and self-reported affective responses to the practice of self-affirmation. In the self-affirmation condition, we asked participants to write about their top-ranked personal value for 5 min and used a writing exercise unrelated to personal values in the control condition. The International Affective Picture System was used to induce positive and negative emotion. Results showed that participants had greater high frequency heart rate variability and respiratory sinus arrhythmia (RSA) when practicing self-affirmation. During negative emotion induction, self-affirmation also led to lower maximum heart rate, higher RSA, and lower ratings of negative affect. Our findings suggest that the act of focusing on an important aspect of self has beneficial effects on psychological and physiological well-being.

Exoneration reduces adult conflict's effects on preschoolers' cognitions, behavioral distress, and physiology.

In this experiment, the authors investigated the influence of exoneration from blame on children's overt behavioral distress and physiological reactivity following the presentation of overheard adult conflict. The participants were 48 children (48-71 months of age) and their mothers. Through random assignment, the authors presented 16 children with statements that exonerated them from an overheard disagreement between two adults, did not address 16 during a similar disagreement, and presented 16 with a neutral discussion of difficulties. Exonerated children responded with less distress than did nonaddressed children, but did not differ from children presented the neutral discussion, except for overt behavioral distress. Nonaddressed children most often blamed themselves for the argument. Exonerating statements may protect children from attributional error and resultant physiological arousal during adult conflict.

Heart rate variability and generalized anxiety disorder during laboratory-induced worry and aversive imagery.

BACKGROUND: To date only a few published studies have examined the effect of disorder-relevant stressors on heart rate variability (HRV) in participants meeting a clinical diagnosis of GAD, with conflicting results. The primary aim of this study was to determine if GAD is associated with lower HRV at rest, and whether vagal regulation during task varies by type (i.e., baseline, anticipation, imagery, or worry). METHODS: This study investigated resting cardiac vagal tone and vagal regulation in a sample of 40 participants with or without a validated diagnosis of generalized anxiety disorder (GAD). High-frequency heart rate variability (HF-HRV) was used to index cardiac vagal activity. RESULTS: GAD was associated with vagal withdrawal during both imagery and worry inductions, but no group differences in resting vagal tone or worry were observed. LIMITATIONS: Methodological limitations include inherent limits to generalizability of laboratory-based findings; specifically worry induction and cardiac reactivity to lab-based stressors. CONCLUSIONS: The results support the notion that GAD is associated with vagal withdrawal during active bouts of idiographic worry and imagery, and question the assumption that GAD is associated with low resting vagal tone. In light of polyvagal theory these findings provide additional support for the presence of emotion regulation deficits in GAD, and identify specific ANS processes that underlie GAD.

Shoulder symptoms and function in geriatric patients.

BACKGROUND AND PURPOSE: Musculoskeletal problems, including shoulder pain, are common in the general population and are often cited as reasons for physician visits. Although many risk factors for shoulder pain are postulated, the effects of shoulder pain on functional level and perceived quality of life are poorly characterized in older adults. In this study, we set out to determine the prevalence and impact of shoulder symptoms and dysfunction in an older adult veteran population. METHODS: A chart review, cross-sectional survey, and examination were performed. A sample of 93 individuals, aged 60 years or older, was recruited from a primary clinic outpatient waiting room at the Clement J. Zablocki VA Medical Center in Milwaukee, Wisconsin. Patients were asked about shoulder symptoms and self-assessed health and completed the Stanford Modified Health Assessment Questionnaire. A series of 3 shoulder maneuvers was used to assess shoulder mobility and pain. The presence of diabetes and statin use was documented. A more thorough chart review was performed on individuals who reported shoulder pain and disability. RESULTS: Severe shoulder pain was common in the study group, reported by 31% of all participants. Functional limitation measured by the Modified Health Assessment Questionnaire and answering "yes" to greater difficulty performing daily tasks was associated with reduced internal rotation, which was present in almost 36% of all participants. Symptoms were often bilateral. No statistically significant risk factors emerged in this small sample, but suggestive trends were apparent. Interestingly, few patients reported discussing these problems with their providers, and shoulder-related problems were documented in only 10% of corresponding problem lists of symptomatic patients. CONCLUSIONS: With an aging population, the high prevalence of shoulder pain may have considerable impact on public health. It will become increasingly important to define risk factors, delineate etiologies, and devise new management strategies for patients with symptomatic shoulder disease.

Correlates of negative physical health in call center shift workers.

The call center industry, a burgeoning sector is characterized by unique job demands, which render it susceptible to high attrition rates and negative health concerns. This study examined the relationship between job stress from interpersonal factors, job stress from work factors, coping, inadequate sleep, and negative physical health reports among call center shift workers (n = 239), a relatively under-researched population. Inadequate sleep and job stress from interpersonal factors were associated with negative physical health outcome for the participants in this study. Further, spending longer in the call center industry was associated with negative health outcome for the shift worker participants.

Effect of mandatory parental notification on adolescent girls' use of sexual health care services.

CONTEXT: Mandatory parental notification for adolescents to obtain prescribed contraceptives is a controversial issue. Recently, legislation that would prohibit prescribed contraceptives for adolescents without parental involvement was introduced in 10 states and the US Congress. OBJECTIVE: To determine the effect of mandatory parental notification for prescribed contraceptives on use of sexual health care services by adolescent girls. DESIGN, SETTING, AND PARTICIPANTS: Girls younger than 18 years and seeking services at all 33 Planned Parenthood family planning clinics in Wisconsin (n = 1118) were surveyed during the spring of 1999. A response rate of 85% was achieved, yielding a sample of 950 girls. MAIN OUTCOME MEASURES: Percentages of girls who reported that they would stop using all sexual health care services, delay testing or treatment for human immunodeficiency virus (HIV) or other sexually transmitted diseases (STDs), or discontinue using specific (but not all) services because of parental notification. RESULTS: Fifty-nine percent (n = 556) indicated they would stop using all sexual health care services, delay testing or treatment for HIV or other STDs, or discontinue use of specific (but not all) sexual health care services if their parents were informed that they were seeking prescribed contraceptives. Eleven percent indicated they would discontinue or delay STD tests or treatment, even though the survey made it clear that mandatory parental notification would occur only for prescribed contraceptives. Analyses comparing girls of different ages and races and from urban vs rural clinics showed that, although the 17-year-olds and African American girls were significantly less likely to stop using sexual health care services with mandatory parental notification, roughly half of the 17-year-olds (56%) and African American girls (49%) indicated that they would stop using all sexual health care services, delay testing or treatment for HIV or other STDs, or discontinue use of specific (but not all) services with mandatory parental notification. CONCLUSION: Mandatory parental notification for prescribed contraceptives would impede girls' use of sexual health care services, potentially increasing teen pregnancies and the spread of STDs.
