Effects of aromatherapy on sore throat, nasal symptoms and sleep quality in adults infected with COVID-19: A randomized controlled trial.

Background: Patients with coronavirus disease 2019 (COVID-19) usually complain of fever, cough, and sore throat. This study examined the effects of aromatherapy on sore throat, nasal symptoms, stress, fatigue, and sleep quality by administering it to adults with post-COVID-19 condition. Methods: This study was conducted in a randomised controlled design. Its target population were adults who were released from COVID-19 quarantine treatment within 45 days from infection onset and capable of performing daily activities after isolation treatment. The participants were randomised into aromatherapy group (AG) and control group (CG). To test experimental treatment effects, the levels of sore throat, nasal symptoms, stress, fatigue and sleep quality were measured at the baseline (pre-test) and after the trial (post-test), using the numerical rating scale for sore throat, stress and fatigue, the Total Nasal Symptoms Score for nasal symptoms, and the Korean Version of Modified Leeds Sleep Evaluation Questionnaire for quality of sleep. Results: After experimental treatment, there was a significant difference in sore throat in AG compared to CG on the 3rd day (t=-2.022 p=0.048) and 4th day (t=-2.450, p=0.017) of treatment. There was also a significant difference in fatigue between AG and CG on the 2nd day(t=-2.748, p=0.008), 3rd day (t=-2.948, p=0.005) and 4th day (t=-3.084, p=0.003) of treatment. There was no significant difference in TNSS, stress, and sleep quality between the two groups after the experimental treatment. Conclusion: Inhaling aroma essential oils reduced sore throat and fatigue in adults with post-COVID-19 condition, demonstrating the feasibility of aromatherapy as an effective treatment. Trial registration: The study was registered with Clinical Research Information Service (KCT0008029).

A randomized controlled trial of pectoralis major myofascial release massage for breastfeeding mothers: breast pain, engorgement, and newborns' breast milk intake and sleeping patterns.

PURPOSE: Supportive interventions to improve breastfeeding practice are needed in nursing. This study investigated the effects of pectoralis major myofascial release massage (MRM) on breast pain and engorgement among breastfeeding mothers and on breast milk intake and sleep patterns among newborns. METHODS: Breastfeeding mothers who had delivered between 37 and 43 weeks and had 7-to 14-dayold newborns were recruited from a postpartum care center in Gunpo, Korea. Participants were randomized to the MRM or control group. The outcome variables were breast pain and breast engorgement among breastfeeding mothers and breast milk intake and sleep time among newborns. The experimental treatment involved applying MRM to separate the pectoralis major muscle and the underlying breast tissue in the chest. After delivery, the first MRM session (MRM I) was provided by a breast specialist nurse, and the second (MRM II) was administered 48 hours after MRM I. RESULTS: Following MRM, breast pain (MRM I: t=-5.38, p<.001; MRM II: t=-10.05, p<.001), breast engorgement (MRM I: right, t=-1.68, p =.100; left, t=-2.13, p=.037 and MRM II: right, t=-4.50, p<.001; left, t=-3.74, p<.001), and newborn breast milk intake (MRM I: t=3.10, p=.003; MRM II: t=3.09, p=.003) differed significantly between the groups. CONCLUSION: MRM effectively reduced breast engorgement and breast pain in breastfeeding mothers, reducing the need for formula supplementation, and increasing newborns' breast milk intake. Therefore, MRM can be utilized as an effective nursing intervention to alleviate discomfort during breastfeeding and to improve the rate of breastfeeding practice (clinical trial number: KCT0002436).

Effects of Virtual Reality Exercise Program on Blood Glucose, Body Composition, and Exercise Immersion in Patients with Type 2 Diabetes.

BACKGROUND: This study is a preliminary study to examine the effect of a virtual reality exercise program (VREP) on type 2 diabetes patients. METHOD: This is a randomized controlled trial for patients with type 2 diabetes (glycated hemoglobin ≥ 6.5%), diagnosed by a specialist. The virtual reality environment was set up by attaching an IoT sensor to an indoor bicycle and linking it with a smartphone, enabling exercise in an immersive virtual reality through a head-mounted display. The VREP was implemented three times a week, for two weeks. The blood glucose, body composition, and exercise immersion were analyzed at baseline, and two weeks before and after the experimental intervention. RESULT: After VREP application, the mean blood glucose (F = 12.001 p < 0.001) and serum fructosamine (F = 3.274, p = 0.016) were significantly lower in the virtual reality therapy (VRT) and indoor bicycle exercise (IBE) groups than in the control group. There was no significant difference in the body mass index between the three groups; however, the muscle mass of participants in the VRT and IBE groups significantly increased compared with that of the control (F = 4.445, p = 0.003). Additionally, exercise immersion was significantly increased in the VRT group compared with that in the IBE and control groups. CONCLUSION: A two week VREP had a positive effect on blood glucose, muscle mass, and exercise immersion in patients with type 2 diabetes, and is highly recommended as an effective intervention for blood glucose control in type 2 diabetes.

Virtual Reality Exercise Program Effects on Body Mass Index, Depression, Exercise Fun and Exercise Immersion in Overweight Middle-Aged Women: A Randomized Controlled Trial.

Background: This study explored the effects of a virtual reality exercise program on overweight middle-aged women. Methods: This randomized controlled trial included women 40−65 years of age with a body mass index (BMI) of 23 kg/m2 or more living in Daejeon City. The virtual reality environment was set up by attaching an IoT sensor to an indoor bicycle and linking it with a smartphone, enabling exercise in an immersive virtual reality through a head-mounted display. Results: In the virtual reality exercise group, the BMI was significantly decreased after the 8-week intervention compared with the baseline value (F = 59.491, p < 0.001). The depression scores were significantly different among the three groups, with the intervention effect being more significant in the virtual reality exercise group than in the indoor bicycle exercise and control groups (F = 3.462, p < 0.001). Furthermore, the levels of exercise fun (F = 12.373, p < 0.001) and exercise immersion (F = 14.629, p < 0.001) were significantly higher in the virtual reality exercise group than in the indoor bicycle exercise and control groups. Conclusions: The virtual reality exercise program positively affected the BMI and the levels of depression, exercise fun, and exercise immersion in overweight middle-aged women. It is an effective home exercise program for obesity management in this population.

The effects of listening to healing beat music on adults' recovery from exposure to stressful stimuli: A randomized controlled trial.

BACKGROUND: Musical auditory stimulation can affect the brain and autonomic nervous system, resulting in psychological and physical relaxation. In particular, listening to healing beat music with a tempo synchronized with an individual's heart rate can make a person feel comfortable. This study investigated whether healing beat music, utilized as a heartbeat-matched auditory stimulus, could be employed to improve patient recovery after exposure to stressful stimuli. METHODS: This study was a randomized controlled trial and participants were adults above age of 20 who voluntarily participated. As outcome variables, stress index, BIS index, sympathetic nerve activity, and blood pressure were measured and compared at 5 min intervals. RESULTS: Following the treatment, the stress index (F = 3.78, p < .001), BIS index (F = 5.61, p < .001), and systolic blood pressure (F = 3.14, p =.019) of the a healing beat music listening group (HBMG) were significantly lower than those of the control group (CG). More specifically, the stress index (P <.05) and the BIS index (P <.05) of the HBMG were lower than the indices of the preferred music listening group (PMG) and the CG at 30 min. CONCLUSIONS: Listening to healing beat music with a tempo synchronized with the heart rates of the participants had the effect of lowering stress index and systolic pressure. Accordingly, healing beat music may be utilized as a treatment method to relieve stress in both clinical and daily life contexts.

The Effects of Aroma Essential Oil Inhalation on Stress, Pain, and Sleep Quality in Laparoscopic Cholecystectomy Patients: A Randomized Controlled Trial.

PURPOSE: Patients undergoing cholecystectomy report experiencing stress related to the surgery, complaining of pain and poor sleep quality. Aromatherapy is known to have positive effects on these complaints. However, the effect of aromatherapy on cholecystectomy patients has yet to be determined. The aim of this study, therefore, was to investigate the effects of aromatherapy on laparoscopic cholecystectomy patients' stress, pain, and sleep quality. METHODS: This study was a randomized controlled trial involving 69 adults who underwent laparoscopic cholecystectomy. Essential oil therapy was given to an intervention group, and almond oil was given to a placebo group. The outcome variables were stress, pain, and sleep quality. RESULTS: There were no differences between the groups in terms of demographic and clinical characteristics and pretreatment dependent variables. After the intervention, subjective stress (F = 7.43, p < .001), objective stress (F = 2.70, p = .034), parasympathetic nerve activity (F = 2.65, p = .036), pain (F = 8.74, p < .001), analgesics administration (F = 22.43, p < .001), and sleep quality (F = 5.23, p < .001) were significantly different between the intervention, placebo, and control groups. Sympathetic nerve activity was not significantly different. The effect sizes regarding the sleep quality of the intervention versus control group and the intervention versus placebo group were 1.92 and 1.52, respectively. CONCLUSION: Postoperative aromatherapy received by cholecystectomy patients was effective in reducing stress and pain and improving sleep quality. No side effects of aromatherapy were reported during the experimental treatment.

Effects of a Thermoelectric Element Band on Venipuncture-associated Pain and Anxiety: A Randomized Controlled Trial.

PURPOSE: Venipuncture is an invasive procedure for diagnosis and treatment, which is often attributed to pain and anxiety. In this study, a thermoelectric element (TEE) band was developed to apply heat therapy (40∼45°C), cold therapy (0∼10°C), or thermal grill illusion (TGI) therapy (40∼45°C, 0∼10°C) to cause an illusion of pain by simultaneously applying heat and cold. This band was subsequently used to investigate its effect on patient pain, anxiety, and satisfaction. METHODS: This was a randomized controlled study. Participants, who were to undergo venipuncture, were randomly assigned to the heat therapy, cold therapy, TGI therapy, or control groups. Each group had 30 participants. The interventions were employed for 10 seconds during venipuncture, and the pain, anxiety, and satisfaction were measured before and after the procedure. RESULTS: Subjective pain, anxiety, and physiological responses after TEE band intervention were not significantly different between the four groups. However, there was a significant difference in satisfaction (F = 4.21, p = .007) between the four groups, and the cold therapy group showed the highest satisfaction. CONCLUSION: In this study, when heat, cold, and TGI therapy were applied with a TEE band, pain and anxiety relief effects were not confirmed, but satisfaction was high. TEE band is a newly developed product that can easily apply hot and cold treatments without using ice packs or hot water packs. Further studies with various individual characteristics of chronic pain or repeated venipuncture are warranted to evaluate the effect of TEE.

The Effects of Dietary Education Interventions on Individuals with Type 2 Diabetes: A Systematic Review and Meta-Analysis.

As the incidence and prevalence of diabetes increases, intervention through dietary education is becoming more important for diabetes control. This systematic review examines the evidence for the efficacy of dietary education interventions on diabetes control. The study subjects were patients with type 2 diabetes, and the main outcome variable was glycosylated hemoglobin level (HbA1c). The target studies were randomized controlled trials. Thirty-six studies were included in the analysis, of which 33 were included in the meta-analysis. The effect size between dietary education and general interventions was -0.42 (n = 5639, MD = -0.42; 95% CI -0.53 to -0.31) and was significantly different (Z = 7.73, p < 0.001). When subgroup analyses were performed following the application periods, intervention methods, and intervention contents, the mean differences in 4-6-month application, individual education, and diet-exercise-psychosocial intervention were -0.51, (n = 2742, 95% CI -0.71 to -0.32), -0.63 (n = 627, 95% CI -1.00 to -0.26), and -0.51 (n = 3244, 95% CI -0.71 to -0.32), respectively. Dietary education interventions provided for at least 3 months were highly effective in controlling HbA1c levels. Regarding the education method, individualized education was more effective, and contact or non-contact education may be applied for this. Combining diet, exercise, and psychosocial intervention is more effective than diet education alone.

Antimicrobial and hand hygiene effects of Tea Tree Essential Oil disinfectant: A randomised control trial.

BACKGROUND: Hand hygiene is paramount in preventing healthcare-associated infections in medical environments and the spread of infectious diseases in non-medical environments. AIMS: This study used a randomised controlled trial to investigate the effects of a tea tree (Melaleuca alternifolia) oil disinfectant on hand disinfection and skin condition. METHODS: A tea tree oil group received 5 mL of 10% tea tree oil disinfectant mixed in a ratio of 2:2:1:15 of Melaleuca alternifolia oil, solubiliser, glycerin and sterile distilled water. Data collection took place between April 9 and April 13, 2018. The subjects were 112 healthy adults. An alcohol group received 2 mL of a gel-type hand sanitiser comprising 83% ethanol used without water; a benzalkonium chloride group received 0.8 mL of a foam-type hand sanitiser containing benzalkonium chloride used without water and a control group received no treatment. Subjective skin condition, transepidermal water loss and adenosine triphosphate were assessed, and a microbial culture test was performed following treatment. RESULTS: The general characteristics and the pretreatment dependent variables did not differ significantly by group. Posttreatment adenosine triphosphate log10 values significantly differed across all four groups (F = 3.23, P = .025). Similarly, posttreatment bacterial density log10 values differed significantly across the tea tree oil, alcohol, benzalkonium chloride and control groups (F = 91.71, P < .001). CONCLUSION: The study confirmed that tea tree oil disinfectant is effective for hand disinfection. Accordingly, tea tree oil disinfectants may be introduced to nursing practice as a new hand hygiene product to prevent and reduce healthcare-associated infections.

A qualitative study on the experience of acupuncture treatment in infertile women.

BACKGROUND: This study aimed to record and analyze the experiences of infertile women who underwent acupuncture treatment. METHODS: This is a qualitative study in which in-depth interviews were conducted with women who underwent acupuncture as a treatment for infertility from the viewpoint of phenomenology, a method of understanding human behavior in the general human and social context, and grasping the nature of the experience in depth. The study participants were 12 women who had been receiving acupuncture treatment for infertility for more than 3 months. RESULTS: After analyzing the statements of the participants' experiences, the main concerns regarding infertility were "embarrassed by unexpected infertility," "overwhelmed with negative feelings," "blocking and defense," "sex as a duty," and "repeatition of expectations and failures." Significant statements regarding acupuncture treatments were "body warmth," "becoming a body," "care of the mind," "last trust and hope," and "difficulties of waiting." The experience with supporter was love-hate relationships, and the experience of the children's meaning was expressed as "precious beings in life." CONCLUSION: The results of this study suggest that acupuncture treatment for infertility in women results in positive thinking through changes in the body as well as through increased hope. Participants experienced a feeling of warmth in their bodies, regular menstrual cycle, and reduced fatigue through acupuncture treatment, indicating a state of psychological stability.

Deterioration of Sleep Quality According to Glycemic Status.

Background: Type 2 diabetes mellitus (T2DM) is a progressive disease with multiple complications. The present study aimed to determine the effects of glycemic status on sleep quality in individuals with T2DM, prediabetes, and normal glucose tolerance (NGT). Methods: A total of 90 participants were categorized into three groups, T2DM (n=30), prediabetes (n=30), and NGT (n=30). Objective sleep quality was measured with the actigraph wrist-worn device over 3 nights and subjective sleep quality was evaluated with a questionnaire. Results: The duration of diabetes in the T2DM group was 2.23 years and the glycosylated hemoglobin (HbA1c) levels in the T2DM, prediabetes, and NGT groups were 7.83%, 5.80%, and 5.31%, respectively. Sleep efficiency decreased across the T2DM, prediabetes, and NGT groups (86.25%, 87.99%, and 90.22%, respectively; P=0.047). Additionally, HbA1c levels revealed a significant negative correlation with sleep efficiency (r=-0.348, P=0.001). The sleep quality questionnaire results were similar among the three groups. Conclusion: Although the participants in the present study were not necessarily conscious of their sleep disturbances, deterioration in sleep quality progressed according to glycemic status.

[Effect of Resistance Exercise Program for Middle-Aged Women with Myofascial Pain Syndrome on Shoulder Pain, Angle of Shoulder Range of Motion, and Body Composition Randomized Controlled Trial, RCT].

PURPOSE: This study aimed to identify the effects of myofascial pain syndrome on shoulder pain, range of motion, and body composition around the shoulder in middle-aged women. METHODS: A total of 72 women participated in the randomized controlled trial. The subjects were grouped into an experimental group (n=39) and a control group (n=33). The experimental group received a resistance exercise program using an elastic band for 8 weeks, 3 days a week. The control group followed a normal daily for 8 weeks. Measurements were conducted three times; before the experimental treatment (pre-test), the 2nd and 8th weeks after treatment. RESULTS: Regarding the general characteristics and homogeneity of the dependent variables, there were no significant differences between the two groups, except for the thickness of the left and right muscles and the left fat. After treatment, shoulder pain was significantly different between the two groups (F=18.54, p<.001) and the range of shoulder motion was significantly different (left, F=86.70, p<.001; right, F=98.66, p<.001). Furthermore, there were a significant differences in the thickness of muscles between the two groups (left, F=40.20, p<.001; right, F=29.57, p<.001); however, the thickness of fat was not significantly different. CONCLUSION: The resistance exercise program reduces shoulder pain and improves the range of motion of the shoulder joint and increases muscle mass on around the shoulder. It suggests to conduct a study to confirm the long-term exercise effect.

Understanding of Factors Influencing Happiness of Middle-Aged Women in Korea Based on Maslow's Hierarchy of Needs.

OBJECTIVE: Middle-aged women experience a lot of events of physical changes and various mental conflicts. The purpose of this study is to determine variables related to happiness, and to make and verify the model for happiness of middle-aged women. METHODS: We constructed conceptual model for happiness of middle-aged women in Korea, based on Maslow's hierarchy of needs. This model consisted of three exogenous variables (health status, financial distress, and social support) and three endogenous variables (selfesteem, positive thinking, and happiness). For middle-aged women in Korea, we returned 442 questionnaires of 460 participants. RESULTS: Model fit of the modified model was satisfied; χ2=102.108, GFI=0.959, CMIN/DF=2.917, RMSEA=0.068, AGFI=0.922, CFI=0.977, SRMR=0.0368. Happiness was explained by 82% through health status, financial distress, social support, self-esteem, and positive thinking. As Maslow's hierarchy of needs, happiness of middle-aged women is related to basic needs (health status, financial distress, and social support), psychological needs (self-esteem and positive thinking) and self-fulfillment needs (happiness). CONCLUSION: Our study shows that it is required intervention for meeting basic factor such as health status, financial distress and social support in order to increase happiness of middle-aged women.

A Systematic Review of Breast Care for Postpartum Mothers.

PURPOSE: The purpose of this study was to identify nursing interventions for the postpartum breast care of mothers and determine the effectiveness of interventions for breast pain and engorgement by systematic review. METHODS: Eight national and international databases were reviewed to retrieve and collect randomized controlled trial and controlled clinical trial literature published up to March 2015. Two reviewers independently selected the studies and performed data abstraction and validation. The risk of bias was assessed using Cochrane criteria. A meta-analysis of the studies was performed to analyze the data. RESULTS: The meta-analysis showed that breast massage, along with routine breast care, resulted in a 3.52-point reduction in pain on a 10-point visual analogue scale. Meta-analysis of therapy with cold cabbage leaves and routine breast care showed a pain reduction of 0.54 points. Meta-analysis of cold cabbage leaf application in the experimental group versus cold compress therapy in the comparison group showed a pain reduction of 0.44 points. Meta-analysis of cold cabbage leaf application and routine breast care showed an engorgement reduction of 0.67 points. CONCLUSION: The results of the analysis of 12 articles showed that hot and cold compresses, breast massage, and cabbage application were effective for postpartum breast pain and engorgement.

The efficacy of simulation-based and peer-learning handover training for new graduate nurses.

BACKGROUND: Nursing handovers are a crucial nursing practice for patient safety and continuity of nursing care. As a strategy to improve nursing handovers, it has been suggested that new graduate nurses receive training in how to conduct handovers. OBJECTIVES: The purpose of this study was to examine the effects of simulation-based handover training and peer-learning handover training on clinical competence regarding handovers and clinical judgment among new graduate nurses. DESIGN: Quasi-experimental research using a nonequivalent control group post-test design. PARTICIPANTS: A convenience sample of 55 new graduate nurses with no clinical experience who expected to work at a university hospital were selected. METHODS: We measured participants' clinical competence regarding handovers and clinical judgment immediately after completing a training program and after 1 month of working at a hospital to examine the immediate and latent effects of simulation-based and peer-learning handover training, respectively. A researcher-developed clinical competence instrument regarding handovers and a clinical judgment instrument based on the Lasater Clinical Judgment Rubric were used. To identify differences in the effects of simulation-based and peer-learning handover training, we analyzed the data using the independent t-test and paired t-test. When evaluating the latent effects, the participants wrote self-reflection reports. RESULTS: There were no significant differences in the immediate effects of the simulation-based training and the peer-learning training. In contrast, in the evaluation of the latent effects, new graduate nurses who received simulation-based training showed significantly higher clinical competence regarding handovers (p = .020) and clinical judgment (p = .033) than their counterparts who received peer-learning training. In the self-reflection reports, 19 participants stated that they had gained more confidence with handovers. CONCLUSION: We suggest that simulation-based handover training contributes more to the improvement of new graduate nurses' clinical competence regarding handovers and clinical judgment than peer-learning training.

Effects of aromatherapy on dysmenorrhea: A systematic review and meta-analysis.

OBJECTIVE: Menstrual pain is not a disease, but it is a problem that periodically makes women uncomfortable during menstrual cycles. There has been a continuing effort to alleviate menstrual cramps in the medical field. Aromatherapy, one of the alternative complementary therapies, has been used as a way to alleviate menstrual cramps, but there is still little evidence of how to use it. Therefore, in this study, we tried to find and provide the evidence of relieving effects of menstrual cramps. DESIGN: This study involved a systematic review and meta-analysis. The study was to identify the effects of aromatherapy on menstrual pain through a systematic review of the relevant literature from Korea and abroad and a meta-analysis of the data from studies meeting our inclusion criteria. DATA SOURCES: We obtained articles published in English from PubMed, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and the Cochrane Central Register of Controlled Trials (CENTRAL), and we also obtained articles by searching the Korean databases Research Information Service System (RISS), DBPIA, and Korean Studies Information Service System (KISS). REVIEW METHODS: A systematic review was performed on all searchable articles published form inception to October 17, 2016, using the international and Korean databases noted above. The search terms used was ((aromatherapy OR aroma* OR essential oil) AND (dysmenorrhea OR menstrual pain)). Articles were selected for analysis from among the retrieved articles based on the key questions and the inclusion and exclusion criteria using a PRISMA flow diagram. The 21 articles entire texts were reviewed and qualitatively analyzed while seven articles were quantitatively analyzed using RevMan software ver. 5.3. RESULTS: In a comparison between the experimental groups, which received an aromatherapy intervention, and the control groups, which received no treatment of any kind, the dysmenorrhea score in the experimental group decreased by 2.67 points (mean difference -2.67), showing a statistically significant difference(Z = 7.79, p < .001, Higgins I2 = 0%). Compared to the placebo group, which received a placebo oil treatment, the dysmenorrhea score in the experimental group decreased by 1.71 points (mean difference, -1.71), showing a statistically significant difference (Z = 4.51, p < .001), but high heterogeneity (Higgins I2 = 81%). CONCLUSIONS: Aromatherapy was an effective intervention for reducing dysmenorrhea. However, because the analysis showed that the aroma intervention methods were diverse and that the basis for the intervention methods was weak, the possibility of randomization bias was high.

The Effects of Aromatherapy on Intensive Care Unit Patients' Stress and Sleep Quality: A Nonrandomised Controlled Trial.

BACKGROUND: Stress has both physiological and psychological effects and can negatively impact patients' treatment and recovery. We examined whether the aromatherapy alleviated patients' stress and improved their sleep quality and provided data that can be utilized in clinical settings. METHODS: This was a nonrandomised controlled experimental study. Participants included lucid adult patients who were admitted to the intensive care unit and had spent more than two nights there. The experimental treatment required participants to engage in deep breathing with essential oils as part of the aromatherapy. The control group was instructed to go to sleep without receiving the lavender aroma oil. RESULTS: The experimental group and control group showed a significant difference in perceived stress (F = 60.11, p < .001), objective stress index (F = 25.65, p < .001), systolic blood pressure (F = 9.09, p < .001), diastolic blood pressure (F = 2.47, p = .046), heart rate (F = 5.71, p < .001), and sleep quality (F = 109.46, p < .001). CONCLUSIONS: The results revealed that aromatherapy alleviated stress and improved sleep quality in intensive care unit patients after 2 days of the experimental treatment. These results demonstrate that aromatherapy affects stress and sleep quality, thus indicating its value in nursing interventions. This trial is registered with KCT0002344.

[Effects of Aromatherapy on Menopausal Symptoms, Perceived Stress and Depression in Middle-aged Women: A Systematic Review].

PURPOSE: This study was a systematic review to evaluate the effects of aromatherapy on menopausal symptoms, perceived stress and depression in middle aged-women. METHODS: Eight databases were searched from their inception September 8, 2015. Two reviewers independently performed the selection of the studies, data abstraction and validations. The risk of bias was assessed using Cochrane criteria. For analysis of the data, a meta-analysis of the studies was performed. RESULTS: From the electronic databases, 73 articles were selected, and 19 removed due to duplication. After two reviewers read the abstracts of 54 studies, 34 studies were selected. Complete papers for 34 original articles were read and, 12 studies which met selection criteria were reviewed and the effects of aromatherapy on menopausal symptoms, stress and depression analyzed using meta-analysis with RevMan. In the 2 studies which included Randomized Controlled Trials testing of aromatherapy on menopausal symptoms and comparison of control and placebo groups were done. Aromatherapy massage was favorably effective in reducing the menopausal symptoms compared to the control group (n=118, MD=-6.33; 95% CI -11.51 to -1.15), and compared to the placebo group (n=117, MD=-4.14; 95% CI -7.63 to -0.64). Also aromatherapy was effective in reducing stress (n=72, SMD=-0.64; 95% CI -1.12 to -0.17) and depression (n=158, MD=-5.63; 95% CI -10.04 to -1.22). CONCLUSION: There is limited evidence suggesting that aromatherapy for middle-aged women may be effective in controlling menopausal symptoms, perceived stress and depression.
