BackgroundPatients with chronic conditions like hypertension may experience many negative emotions which increase their risk for the development of mental health disorders particularly anxiety and depression. For Ghanaian patients with hypertension, the interaction between hypertension and symptoms of anxiety, depression and stress remains largely unexplored. To fill this knowledge gap, the study sought to ascertain the prevalence and role of these negative emotions on anti-hypertensive medication adherence while taking into account patients’ belief systems.MethodsThe hospital-based cross-sectional study involving 400 hypertensive patients was conducted in two tertiary hospitals in Ghana. Data were gathered on patient’s socio-demographic characteristics, anxiety, depression and stress symptoms, spiritual beliefs, and medication adherence.ResultsHypertensive patients experienced symptoms of anxiety (56%), stress (20%) and depression (4%). As a coping mechanism, a significant relation was observed between spiritual beliefs and anxiety (x2 = 13.352, p = 0.010), depression (x2 = 6.205, p = 0.045) and stress (x2 = 14.833, p = 0.001). Stress among patients increased their likelihood of medication non-adherence [odds ratio (OR) = 2.42 (95% CI 1.06 – 5.5), p = 0.035].ConclusionThe study has demonstrated the need for clinicians to pay attention to negative emotions and their role in medication non-adherence. The recommendation is that attention should be directed toward the use of spirituality as a possible mechanism by which negative emotions could be managed among hypertensive patients.

BackgroundMedication non-adherence is often a predominant problem in the management of hypertension and other chronic conditions. In explaining health behaviours, social determinants like spirituality and religiosity are increasingly identified to impact health and treatment. Although a number of researchers have found spirituality and religiosity to be primary resources among persons dealing with chronic disability and illness, studies relating this specifically to medication adherence have been limited.MethodsOur study sought to examine the interrelationship between spirituality/ religiosity and medication adherence among 400 hypertensive patients 18 years old and above. Spiritual Perspective Scale, Duke Religion Index, and the Morisky Medication Adherence Scale were used to determine spirituality, religiosity and medication adherence respectively.ResultsThe majority (93.25%) of patients poorly adhered to their medications. While high spiritual and religious beliefs formed core components of the lifestyles of patients, spirituality (p = 0.018) and not religiosity (p = 0.474) related directly with medication non-adherence. Likewise, after controlling for demography and other medical co-morbidities, patients with high spirituality were 2.68 times more likely to be poorly adherent than patients who place lower emphasis on the association between spirituality and health.ConclusionOur study suggests that while spirituality/ religiosity was dominant among hypertensive patients, these spiritual attachments of patients with a supreme being potentially increased their trust in the expectation of divine healing instead of adhering adequately with their anti-hypertensive medications.

BackgroundThe use of complementary and alternative medicine (CAM) is widespread and high utilization rates are associated with people who have chronic conditions like hypertension which management requires adherence to conventional treatment. Often however, the use of alternative medicines has been linked to negative health outcomes. The purpose of the study therefore was to evaluate the pattern, determinants and the association between CAM use and the adherence behaviour of hypertensive patients in Ghana.MethodsA cross-sectional study was conducted using 400 hypertensive patients attending Korle-bu and Komfo Anokye Teaching Hospitals in Ghana from May to July, 2012. Information was gathered on the socio-demographic characteristics of patients, CAM use, and adherence using the 8-item Morisky Medication Adherence Scale (MMAS).ResultsOut of the 400 study participants, 78 (19.5%) reported using CAM with the majority (65.38%) utilizing biological based therapies. About 70% of CAM users had not disclosed their CAM use to their healthcare professionals citing fear and the lack of inquiry by these health professionals as the main reasons for non-disclosure. Males were 2.86 more likely to use CAM than females [odds ratio (OR) = 2.86 (95% CI 1.48 – 5.52), p = 0.002]. Participants who could not afford their medications had 3.85 times likelihood of CAM use than those who could afford their medicines [OR = 3.85 (1.15 – 12.5), p = 0.029]. In addition, a significant relationship between CAM use and experiences of anti-hypertensive side effects was observed, X2 = 25.378, p < 0.0001. CAM users were 2.22 times more likely to be non-adherent than participants who did not use CAM [OR = 2.22 (0.70 – 7.14), p = 0.176].ConclusionHypertensive patients in Ghana have shown utilization for CAM. It is important that healthcare providers understand the patterns and determinants of CAM use among their patients. Intervention programmes can then be incorporated to enhance the desired health outcomes of patients.

BackgroundResearch development is needed in physical activity and sedentary behaviour and their associations with mental health in young people. In Western countries the weather is a key contributing factor of sedentary behaviour in youth. The likely contributing factor of sedentary behaviour among African youth has not been explored. This study examined the association between sedentary behaviour and mental health in African young people.MethodsParticipants were 296 adolescents (150 males, 146 females) aged 13 to 18 years (mean = 14.85 years) living in Ghana. Participants’ physical activity levels were assessed using the Physical Activity Questionnaire for Older Adolescents (PAQ-A) and sedentary behaviour, using the Adolescents Sedentary Activity Questionnaire. Depression was assessed using the Children Depression Inventory and aspects of self-esteem were measured with the Physical Self-worth test and Body Image Silhouette test.ResultsThere was a significant negative correlation between physical activity and mental health independent of sedentary behaviour [depression (r =-0.78, p < 0.001); physical self-worth (r = 0.71, p < 0.001); body dissatisfaction (r =-0.76, p < 0.001)]. Moreover, sedentary behaviour was significantly associated with higher depression (r = 0.68, p < 0.001). Affluence was a significant contributing factor of sedentary behaviour in African young people [t (294) =-7.30, p < 0.001].ConclusionThe present study has found that sedentary behaviour is highly prevalent among African adolescents especially among adolescents from affluent homes. Low levels of physical activity as well as sedentary behaviour is significantly associated with mental health problems among African youth, which is consistent with reports from studies among Western young people. The present research, therefore, contributes new information to the existing literature. Increased physical activities can improve the mental health of adolescents.

Relapse to substance abuse is a global problem and is conceptualized as an integral component of the recovery process. Global statistics on rates of relapse after substance abuse treatment are disturbingly high, averaging about 75% within a 3- to 6-month duration after treatment. This study sought to gain full understanding of the factors that precipitate relapse among substance abusers in Ghana. Data were collected through in-depth interviews with 15 relapsed substance abusers who were previously treated for substance abuse, and three mental health professionals at a psychiatric rehabilitation unit in Ghana. Findings showed that seven factors, including positive/negative emotional reinforcements, sense of loss, interpersonal conflicts, peer influence, familial, religio-cultural, and treatment-based issues complot to instigate and maintain the relapse cycle. The findings provide valuable insights into the relapse phenomenon in Ghana. Clinicians should actively engage family members in the relapse prevention process, and provide insight into religio-cultural relapse precipitants.

Large area highly crystalline MoS 2 and WS 2 thin films were successfully grown on different substrates using radio-frequency magnetron sputtering technique. Structural, morphological and thermoelectric transport properties of MoS 2, and WS 2 thin films have been investigated systematically to fabricate high-efficient thermal energy harvesting devices. X-ray diffraction data revealed that crystallites of MoS 2 and WS 2 films are highly oriented in 002 plane with uniform grain size distribution confirmed through atomic force microscopy study. Surface roughness increases with substrate temperature and it plays a big role in electron and phonon scattering. Interestingly, MoS 2 films also display low thermal conductivity at room temperature and strongly favors achievement of higher thermoelectric figure of merit value of up to 1.98. Raman spectroscopy data shows two distinct MoS 2 vibrational modes at 380 cm −1 for E 1 2g and 410 cm −1 for A 1g. Thermoelectric transport studies further demonstrated that MoS 2 films show p-type thermoelectric characteristics, while WS 2 is an n-type material. We demonstrated high efficient pn-junction thermoelectric generator device for waste heat recovery and cooling applications.
