One of the major risk factor for CVDs is hypertension. Regular practice of ingestion of lemon juice as complimentary therapy would have a positive impact in controlling blood pressure; since it contains vitamin C
A quasi experimental interrupted time series design was adopted for the study. The sample comprised of 50 hypertensive clients, selected using non-probability purposive sampling technique. On day 1 demographic proforma of the clients was collected and blood pressure reading was taken. The clients were then randomly assigned to experimental and control groups. The experimental group was administered 10ml lemon juice diluted in 250ml warm water in the morning, 30 minutes before breakfast for a period of 30 days. The control group received no intervention by the investigator but was advised to carry on with routine treatment. The blood pressure was checked at 15th and 30th day for clients in both experimental and control group
The mean pre-test SBP reading 156.40±8.7 was more than the post-test I 153.44±9.7 and post-test II 143.04±11.0 in the experimental group. The mean pre-test SBP reading 153.28±9.7 is more the than post-test I 149.60±12.0 and post-test II 148.80±11.2 in control group. The mean pre test DBP reading 98.08±3.5 is more than the post-test I 93.84±5.3 and post-test II 88.72±5.0 in the experimental group. The mean pre test DBP reading 96.80±4.2 is more the than post-test I 94.72±5.4 and post-test II 94.48±4.0 in the control group. ANOVA test showed that the F value 61.91 for the SBP was greater than the tabled value t(2, 48) =3.19 and F value 37.85 for the DBP was also greater than the tabled value t(2, 48)=3.19 at 0.05 level of significance. Mann-Whitney ‘Z’ value 0.44 of pre test and post-test I in experimental and control group is less than the tabled value 1.96 and ‘Z’ value 3.24 of pre test and post test II in experimental and control group is greater than the tabled value 1.96 at 0.05 level of significance. There was a significant association of level of SBP with educational status and diet. There is no significance association of levels of DBP with age, gender, religion, education, occupation, diet, duration of diseases, treatment followed and associated illness
Interpretation and conclusion
Study concludes that, lemon juice is a non-pharmacological and cost effective intervention in reducing blood pressure in hypertensive clients.
