Link between Vitamin D and Depression in Young Women

Vitamin D status seems to be related to depression in young women.
A study from Oregon State University in the US suggests a relationship between low levels of vitamin D, and depression in otherwise healthy young women. Those with lower levels of vitamin D were more likely to have clinically significant symptoms over the course of a five-week study. The results were consistent even when researchers took into account other possible explanations, such as time of year, exercise and time spent outside.
A lot of past research has found no association between the two, but much of that research has been based on older adults or special medical populations.

This study focused on young women in the Pacific Northwest because they are at risk of both depression and vitamin D insufficiency. Researchers recruited 185 female college students, aged 18-25, to participate in the study at different times during the academic year. Vitamin D levels were measured from blood samples and participants completed a depression symptom survey over five weeks.

As expected, the women’s vitamin D levels depended on the time of year, with levels dropping during autumn, reaching their lowest in winter, and rising again in the spring. Depression did not show as a clear pattern, prompting the team to conclude that links between vitamin D deficiency and seasonal depression should be studied in larger groups of individuals. They say the study does not conclusively show that low vitamin D levels cause depression, and a clinical trial examining whether vitamin D supplements might help prevent or relieve depression is the logical next step to understanding the link between the two.

Acupuncture better than Standard Care for Anxiety & Depression in Distressed Patients

Acupuncture research from Sweden: acupuncture is better than standard care for anxiety & depression .

Researchers from the University of Gothenburg in Sweden have concluded that at six month follow-up, patients with psychological distress, and treated with either acupuncture or integrative care (acupuncture alongside talking therapy), show more long-term benefit than those given conventional care. Patients were drawn from four GP practices across western Sweden, and comprised 120 adults aged 20 to 55. Primary diagnoses were: depression (30%), anxiety or panic disorders (20%), severe stress (20%), somatic symptoms/pain (20%) and sleep disorders (10%). Acupuncture was given once each week for eight weeks.

Both acupuncture and integrative care were more effective than conventional care, in reducing anxiety and depression whilst improving quality of life. The researchers say their results are in line with earlier findings suggesting the effectiveness of acupuncture for anxiety and depression.

Acupuncture with Antidepressants better than Drugs Alone

Acupuncture is more effective than drug treatment alone.

A pragmatic randomised controlled trial conducted by the Medicines Research Group at the University of East London, has found that patients with depression benefit more when they receive acupuncture in addition to taking SSRI antidepressant medication. (SSRIs include citalopram, fluoxetine, Prozac and seroxat.) A total of 76 patients were randomly allocated to one of two groups: one group was given an SSRI but also received acupuncture, whilst the other group was only given the SSRI. Baseline depression scores for the two groups were 22.2 and 22.1 respectively.

After the first week of treatment, the depression score in the acupuncture group had dropped to 15.6, compared to 18.3 for the second group. This significant difference was maintained to the end of the six week trial, when scores were 6.3 for the acupuncture group, and 8.2 for the drug-alone group.

Acupuncture outperforms Counselling & Usual Care in Depression complicated by Pain

A study published by the British Medical Journal shows that acupuncture outperforms counselling and usual care, in patients who have depression complicated by pain. This follows from a secondary analysis of the study data arising out of the research detailed on 21 January 2014 below.

A total of 755 patients recruited through GP practices across northern England, were randomised to receive acupuncture (302 patients), counselling (302 patients) or usual care alone (151 patients). Patients’ assessment of their pain and general wellbeing revealed that those with moderate to extreme pain were doing better after three months if they received acupuncture compared with those who received either counselling or usual care.

Acupuncture & Counselling Hasten Results in Depression Treatment

Research from the UK: acupuncture and counselling hasten results in depression treatmentA large UK multi-centre, randomised controlled trial has shown that adding either acupuncture or counselling to usual care, can hasten improvements in patients with moderate to severe depression. A total of 755 such patients were recruited from 27 GP practices across northern England, and randomised to one of three groups: acupuncture (302 patients), counselling (302 patients), or usual care alone (151 patients). Over a three month period, patients attended a mean of ten acupuncture sessions or nine counselling sessions. Patients were followed up over twelve months. Usual care, including antidepressants, was available to all three groups.

Compared with usual care alone, both acupuncture and counselling gave significantly greater reductions in depression scores, at both three and twelve months. Antidepressants fail to work in more than half of patients, and many patients would like to be offered drug-free treatment options.
