Foundation: type 2 diabetes mellitus is the most common diabetes in Cuba, which demands an increase in health services, a situation which could affect the quality of care of these patients. Objective: to evaluate the quality of medical care provided to patients with type 2 diabetes in the José Antonio Echeverría polyclinic, in the Cárdenas municipality in 2016. Method: an investigation was carried out on evaluative health systems and services. A sample was calculated and 375 patients were studied, a stratified two-stage cluster sampling was used for the selection. The variables studied were related to the attention and perception of the patients. The instruments applied were built and validated by experts. The processing was carried out by means of the statistical package SPSS version 21.0. Results: the most distant results from the established standards were found in body mass index, only 29, 6 % had normal weight, users satisfaction (52,5 %), and glycemic control (58,1 %). Conclusions: the quality of care was evaluated as unsatisfactory; the results were evaluated as not acceptable. Despite the existence of national guidelines for the clinical control of the diabetic, these are not always met, as confirmed by the number of uncontrolled patients and dissatisfied with the care received.

Foundation: mortality study usually shows death as a single-caused phenomenon, so it is considered necessary to discuss methods which include in the analysis, all diseases recorded in medical death certificates. Objective: to identify the conditions under which the weighted multi-causal approach differs from the classical single causal approach. Method: a descriptive study was conducted and a weighting method was applied to calculate mortality rates from the multiple causes of death of medical death certificates and the classic method that exclusively uses the basic cause. The universe was the total of deaths in the first semester of 2016 in Havana according to death certificates. The causes in which the two methods showed greater differences were identified. Data processing was carried out using the statistical package IBM-SPSS version 21.0. Results: diseases such as heart disease, dementia and Alzheimer's, malignant tumors and asthma did not show differences between the rates calculated by both methods; diseases such as primary essential hypertension, diabetes mellitus and pneumonia, showed important differences. Conclusions: the weighted multi-causal method differs from the classic single causal method, as the cause of interest appears more as secondary and less as basic; the mortality rate according to the weighted multicausal method is higher than that of the classical method for the corresponding cause.

Technology and the rapid growth in the area of brain imaging technologies have forever made for a pivotal role in analyzing and focusing the new views of brain anatomy and functions. The mechanism of image processing has widespread usage in the area of medical science for improving the early detection and treatment phases. Deep neural networks (DNN), till date, have demonstrated wonderful performance in classification and segmentation task. Carrying this idea into consideration, in this paper, a technique for image compression using a deep wavelet autoencoder (DWA), which blends the basic feature reduction property of autoencoder along with the image decomposition property of wavelet transform is proposed. The combination of both has a tremendous effect on sinking the size of the feature set for enduring further classification task by using DNN. A brain image dataset was taken and the proposed DWA-DNN image classifier was considered. The performance criterion for the DWA-DNN classifier was compared with other existing classifiers such as autoencoder-DNN or DNN, and it was noted that the proposed method outshines the existing methods.

This article aimed to determine and compare the timing of long-acting reversible contraceptives (LARC) use (ie, intrauterine device and implant) in Burkina Faso (BF) and DR Congo (DRC) between the intervention and control groups.Patients and Methods: A total of 1120 postpartum women were enrolled and followed up to 12 months postpartum. We used Yam-Daabo trial data which was a multi-intervention, single-blinded, cluster-randomised controlled trial done in primary health-care centres (clusters) in both countries. Centres were randomly allocated to receive the six-component intervention or standard antenatal and postnatal care in matched pairs (1:1). We did a secondary analysis using Royston-Parmar’s semi-parametric model to estimate the effect of the interventions on the median time of LARC uptake.Results: Our analysis included 567 postpartum women in BF (284 in the intervention group and 283 in the control group) and 553 in the DRC (274 in the intervention group and 279 in the control group). After showing an increase in family planning use in these two African countries, Yam Daabo’s interventions showed a reduction of the median time of LARCs adoption in the intervention group compared to the control group in both countries (difference of 39 days in Burkina Faso; difference of 86 days in the DR Congo).Conclusion: The Yam Daabo intervention package resulted in increased and earlier adoption of LARC in rural settings in Burkina Faso and urban settings in DR Congo. Such an intervention could be relevant in similar contexts in Sub-Saharan Africa with very high fertility rates and high unmet needs for contraception.Keywords: family planning, postpartum, long-acting reversible contraceptives, sub-Saharan Africa

ObjectivesPortugal has the highest HIV incidence rate in Western Europe. The proportion assigned to sexual contact between men recently increased to more than 30% of all HIV infections. Men who have sex with men (MSM) are vulnerable to the acquisition of other sexually transmitted infections (STIs), increasing the per-contact risk of HIV infection. Building on syndemic theory, the aim of this analysis was to identify patterns of current sexual behaviour in MSM, and explore their relationship with self-reported current, past STI diagnoses and HIV positive serostatus.DesignA cross-sectional behavioural survey was conducted in Portugal among MSM, using a community-based participatory research approach. Hierarchical cluster analysis was used to identify patterns including behavioural and demographic factors.ResultsThe analysis resulted in six clusters. Three clusters showed higher rates of current STI diagnosis (ranging from 11.7% to 17.1%), past STI diagnosis (ranging from 25.5% to 41.5%) and HIV positive serostatus (ranging from 13.0% to 16.7%). From the three clusters scoring lower on current and past STI and HIV diagnoses, one was characterised by a high number of sexual partners (62% had more than 12 partners in the last year), a high proportion (94.6%) of frequent visits to gay venues to meet sexual partners and high alcohol use (46.1%). The other two clusters scored lower on high risk sexual behaviour.ConclusionFactors other than sexual behaviour appear to reinforce the vulnerability to STIs and HIV of some MSM in this study, suggesting a syndemic of STIs, HIV and other adverse conditions. More research is needed to better understand the drivers of the STI/HIV epidemic in Portuguese MSM, using a concept that goes beyond risk behaviour, to develop effective combination prevention interventions.

Background: Reducing deaths from hypertensive disorders of pregnancy is a global priority. Low dietary calcium might account for the high prevalence of pre-eclampsia and eclampsia in low-income countries. Calcium supplementation in the second half of pregnancy is known to reduce the serious consequences of pre-eclampsia; however, the effect of calcium supplementation during placentation is not known. We aimed to test the hypothesis that calcium supplementation before and in early pregnancy (up to 20 weeks' gestation) prevents the development of pre-eclampsia Methods: We did a multicountry, parallel arm, double-blind, randomised, placebo-controlled trial in South Africa, Zimbabwe, and Argentina. Participants with previous pre-eclampsia and eclampsia received 500 mg calcium or placebo daily from enrolment prepregnancy until 20 weeks' gestation. Participants were parous women whose most recent pregnancy had been complicated by pre-eclampsia or eclampsia and who were intending to become pregnant. All participants received unblinded calcium 1·5 g daily after 20 weeks' gestation. The allocation sequence (1:1 ratio) used computer-generated random numbers in balanced blocks of variable size. The primary outcome was pre-eclampsia, defined as gestational hypertension and proteinuria. The trial is registered with the Pan-African Clinical Trials Registry, number PACTR201105000267371. The trial closed on Oct 31, 2017. Findings: Between July 12, 2011, and Sept 8, 2016, we randomly allocated 1355 women to receive calcium or placebo; 331 of 678 participants in the calcium group versus 320 of 677 in the placebo group became pregnant, and 298 of 678 versus 283 of 677 had pregnancies beyond 20 weeks' gestation. Pre-eclampsia occurred in 69 (23%) of 296 participants in the calcium group versus 82 (29%) of 283 participants in the placebo group with pregnancies beyond 20 weeks' gestation (risk ratio [RR] 0·80, 95% CI 0·61–1·06; p=0·121). For participants with compliance of more than 80% from the last visit before pregnancy to 20 weeks' gestation, the pre-eclampsia risk was 30 (21%) of 144 versus 47 (32%) of 149 (RR 0·66, CI 0·44–0·98; p=0·037). There were no serious adverse effects of calcium reported. Interpretation: Calcium supplementation that commenced before pregnancy until 20 weeks' gestation, compared with placebo, did not show a significant reduction in recurrent pre-eclampsia. As the trial was powered to detect a large effect size, we cannot rule out a small to moderate effect of this intervention.

IntroductionWomen who use contraceptive methods sometimes stop early, use methods intermittently, or switched contraceptive methods. All these events (discontinuations and switching) contribute to the occurrence of unwanted and close pregnancies. This study aimed to explore contraceptive discontinuation and switching during the Yam-Daabo project to measure the effect of interventions on the continuation of contraceptive methods use.MethodsWe conducted a secondary analysis of the Yam-Daabo trial data. We choose the discontinuation and switching of a modern contraceptive method as outcome measures. We performed a survival analysis using the Stata software package to estimate the effect of the interventions on contraceptive discontinuation. We also studied the main reasons for discontinuation and switching.ResultsIn total, 637 out of the 1120 women used at least one contraceptive method (of any type), with 267 women in the control and 370 in the intervention group. One hundred seventy-nine women of the control group used modern methods compared to 279 women of the intervention group with 24 and 32 who discontinued, respectively. We observed no statistically significant association between interventions and modern methods discontinuation and switching. However, modern methods' discontinuation was higher in pills and injectables users than implants and IUDs users. The pooled data comparison showed that, in reference to the women who had not switched while using a modern method, the likelihood of switching to a less or equal effectiveness method among the women of the control group was 3.8(95% CI: 1.8-8.0) times the likelihood of switching to a less or equal effectiveness method among the women of the intervention group. And this excess was statistically significant (p ConclusionThe results of this study show no statistically significant association between interventions and modern methods discontinuation. Discontinuation is more related to the methods themselves than to any other factor.

Background: an earlier adoption of contraceptive methods during the postpartum period could help women to extend the inter-pregnancy interval. This article aimed to determine and compare the timing and dynamics of long-acting and reversible contraceptives (LARC) use (i.e., intra-uterine device and implant) in Burkina Faso (BF) and the DR Congo (DRC).Methods: Study participants were followed up to 12 months postpartum. We used Royston-Parmar's semi-parametric model to estimate the effect of the interventions. All multivariate results were adjusted for covariates found to be imbalanced between the intervention and control groups. We used a Mantel-Haenszel-type method to compare adjusted hazard ratios (aHR) between the two countries. We computed the median time of contraceptive adoption in each group by country.Results: Our analysis included 567 postpartum women in BF (284 in the intervention group and 283 in the control group) and 553 in the DRC (274 in the intervention group and 279 in the control group). Interventions had an effect in LARC use in BF (aHR 1.85; p=0.001) as well as DRC (aHR 2.78; pConclusion: The Yam Daabo intervention package resulted in an increased and earlier adoption of LARC in both rural settings in Burkina Faso and urban settings in DR Congo. Such an intervention could be relevant in similar contexts in Sub-Saharan Africa.Plain English summary: Many studies showed that postpartum family planning use is low and unmet need for contraception following pregnancy is high in low- and middle-income countries. The Yam Daabo cluster-randomised controlled trial showed that a package of six low-technology interventions, designed in a participatory manner and aimed at strengthening routine antenatal and postnatal services in primary health clinics, doubled the proportion of women using short-acting and long-acting reversible modern contraceptives up to 12 months post partum when compared with women using routine care. This paper, which is a secondary analysis of the Yam Daabo trial, focuses on long-acting and reversible contraceptive (LARC) because of their multiples advantages and few disadvantages by reporting the dynamics of LARCs adoption during the first year postpartum. Such an analysis is very relevant because an earlier adoption of LARC in poor countries such as Burkina Faso and the DR Congo, with a high fertility rate, is effective in spacing pregnancies.Yam Daabo’s interventions showed a reduction of the median time of LARCs adoption in the intervention group compared to the control group in both countries (just under 2 months for the median time for LARC adoption in intervention group, difference of 39 days in Burkina Faso; 75 days postpartum for the median time for LARC adoption in intervention group, difference of 86 days in the DR Congo). This is an important point for the decision makers. According to our results, if the women are checked in the six postpartum weeks, as recommended by the WHO about postnatal care in 2013, and exposed to Yam Daabo’s interventions, this might increase an earlier PPFP use and specifically LARC use. Considering the high effectiveness of LARC, this may contribute to prevent unintended pregnancies and extend the inter-pregnancy interval. This is all the more important since most of these countries have very high fertility rates with high unmet needs for contraception. These results have important programmatic implications for countries with similar context.

Objective: The impact of early hormonal contraception (HC) exposure during breastfeeding on child growth and pubertal and behavioural development was assessed using data from the Avon Longitudinal Study of Parents and Children (Avon study).Study design: The Avon study is a prospective cohort study designed to identify environmental factors affecting child health and development (n=14,541; delivery dates: 1 April 1991-31 December 1992). This secondary analysis was restricted to breastfed singleton infants. The main independent predictor variable was HC exposure during the first 8 weeks postpartum. Growth variables were changes from baseline in weight and height at ages 2 and 4 years. Behavioural variables were assessed at age 47 months. Pubertal development was evaluated between ages 8- and 16-years using Tanner scales. Results: 9,508 children were breastfed during the first 4 weeks postpartum; 8,927 had complete data for breastfeeding and HC exposure. Multivariate analyses demonstrated no difference in growth outcome variables between breastfed infants exposed to HC and those who were not. Similarly, no differences in behavioural problems or pubertal development were observed between the two groups.Conclusions: Early HC exposure during breastfeeding did not appear to influence negatively child growth and development. Limitations include short-term exposure to HC, the discrepancy between the timepoints when HC intake and breastfeeding were measured and the missing data, particularly regarding growth measurements Further clinical studies are required to confirm this lack of negative impact.Implications statement: Guidance on the use of HC during breastfeeding remains controversial; however, the Avon study did not detect any signal to suggest that early exposure to HC via breastfeeding has a negative impact on child growth, development or behaviour.

We propose a method for estimating the weight of the light source position to content-based image retrieval (CBIR) through retrieving image data. The image retrieval method makes use of a multi-dimensional descriptor expressing the features of the image. A multi-directional Gabor filter is then applied in order to extract the contour direction of the image, and a color correlation is applied in order to analyze the distribution of the position between the colors in the image. An HSV histogram and chromatic distribution information were obtained for the color composition analysis, and the light source position in the image was estimated for the main region extraction. The relative similarity between the images was measured through a relative comparison between each descriptor. In conventional image retrieval, there is a disadvantage in terms of the large computational intensity required, because the accuracy is degraded when simple information is used or when the result is estimated through a comparison of complex image components. However, the proposed method adds a light source location analysis element in order to ensure accurate retrieval. Image retrieval using the proposed method achieves an average retrieval accuracy of 85%, indicating that its reliability is superior to that of previously described methods.

Background The YAM DAABO study (“your choice” in Mooré) takes place in Burkina Faso and the Democratic Republic of Congo. It has the objective to identify a package of postpartum family planning (PPFP) interventions to strengthen primary healthcare services and determine its effectiveness on contraceptive uptake during the first year postpartum. This article presents the process of identifying the PPFP interventions and its detailed contents. Methods Based on participatory action research principles, we adopted an inclusive process with two complementary approaches: a bottom-up formative approach and a circular reflective approach, both of which involved a wide range of stakeholders. For the bottom-up component, we worked in each country in three formative sites and used qualitative methods to identify barriers and catalysts to PPFP uptake. The results informed the package design which occurred during the circular reflective approach – a research workshop gathering service providers, members of both country research teams, and the WHO coordination team. Results As barriers and catalysts were found to be similar in both countries and with the view to scaling up our strategy to other comparable settings, we identified a common package of six low-cost, low-technology, and easily-scalable interventions that addressed the main service delivery obstacles related to PPFP: (1) refresher training of service providers, (2) regularly scheduled and strengthened supportive supervision of service providers, (3) enhanced availability of services 7 days a week, (4) a counseling tool, (5) appointment cards for women, and (6) invitation letters for partners. Conclusions Our research strategy assumes that postpartum contraceptive uptake can be increased by supporting providers, enhancing the availability of services, and engaging women and their partners. The package does not promote any modern contraceptive method over another but prioritizes the importance of women’s right to information and choice regarding postpartum fertility options. The effectiveness of the package will be studied in the experimental phase. If found to be effective, this intervention package may be relevant to and scalable in other parts of Burkina Faso and the DRC, and possibly other Sub-Saharan countries.

© 2018 The Author(s). Background: Postpartum family planning (PPFP) information and services can prevent maternal and child morbidity and mortality in low-resource countries, where high unmet need for PPFP remains despite opportunities offered by routine postnatal care visits. This study aims to identify a package of PPFP interventions and determine its effectiveness on the uptake of contraceptive methods during the first year postpartum. We hypothesize that implementing a PPFP intervention package that is designed to strengthen existing antenatal and postnatal care services will result in an increase in contraceptive use. Methods: This is an operational research project using a complex intervention design with three interacting phases. The pre-formative phase aims to map study sites to establish a sampling frame. The formative phase employs a participatory approach using qualitative methodology to identify barriers and catalysts to PPFP uptake to inform the design of a PPFP intervention package. The intervention phase applies a cluster randomized-controlled trial design based at the primary healthcare level, with the experimental group implementing the PPFP package, and the control group implementing usual care. The primary outcome is modern contraceptive method uptake at twelve months postpartum. Qualitative research is embedded in the intervention phase to understand the operational reasons for success or failure of PPFP services. Discussion: Designing, testing, and scaling-up effective, affordable, and sustainable health interventions in low-resource countries is critical to address the high unmet need for PPFP. Due to socio-cultural complexities surrounding contraceptive use, this research assumes that this is more effectively accomplished by engaging key stakeholders, including adolescents, women, men, key community members, service providers, and policy-makers. At the individual level, knowledge, attitudes, and behaviors of women and couples toward PPFP will likely be influenced by a set of low-cost interventions. At the health service delivery level, the implementation of this trial will probably require a shift in behavior and accountability of providers regarding the systematic integration of PPFP into their clinical practice, as well as the optimization of health service organization to ensure the availability of competent staff and contraceptive supplies. Trial registration: Retrospectively registered in the Pan African Clinical Trials Registry (PACTR201609001784334, 27 September 2016).

Objective To demonstrate the feasibility and safety of training midlevel healthcare providers (midwives and family nurses) to provide medical abortion and postabortion contraception in underserved areas in Kyrgyzstan. Study design This was an implementation study at four referral facilities and 28 Felsher Obstetric Points in two districts to train their midwives and family nurses to deliver safe and effective abortion care with co-packaged mifepristone–misoprostol and provide contraceptives postabortion. The outcome of abortion — complete abortion, incomplete abortion or o-going pregnancy — was the primary end point measured. An international consultant trained 18 midwives and 14 family nurses (with midwifery diplomas) to provide medical abortion care. Supervising gynecologists based in the referral centers and study investigators based in Bishkek provided monthly monitoring of services and collection of patient management forms. A voluntary self-administered questionnaire at the follow-up visit documented women's acceptability of medical abortion services. All study data were cross-checked and entered into an online data management system for descriptive analysis. Results Between August 2014 and September 2015, midwives provided medical abortion to 554 women with a complete abortion rate of 97.8%, of whom 62% chose to use misoprostol at home. No women were lost to follow-up. Nearly all women (99.5%) chose a contraceptive method postabortion; 61% of women receiving services completed the acceptability form, of whom more than 99% indicated a high level of satisfaction with the service and would recommend it to a friend. Conclusion This study demonstrates that trained Kyrgyz midwives and nurses can provide medical abortion safely and effectively. This locally generated evidence can be used by the Kyrgyz Ministry of Health to reduce unintended pregnancy and expand safe abortion care to women in underserved periurban and rural settings. Implications Success in scaling up midwife/nurse provision of medical abortion in Kyrgyzstan will require registration of mifepristone–misoprostol, regulations permanently allowing midwife/nurse provision, strengthened procurement and distribution systems to prevent stockouts of supplies, preservice training of midwives/nurses and their involvement in district level supervision, monitoring and reporting, and support from supervisors.

BACKGROUND:In rural Burkina Faso, a package of six low-technology, post-partum contraceptive interventions (ie, refresher training for providers, a counselling tool, supportive supervision, daily availability of contraceptive services, client appointment cards, and invitation letters to attend appointments for partners), aimed at strengthening existing primary health-care services and enhancing demand for them, doubled the use of modern contraceptives at 12 months post partum (ie, 55% uptake in intervention recipients vs 29% in routine-care users). This study assessed the effect of a similar package but in urban settings of Kinshasa province, Democratic Republic of the Congo, in an effort to reduce the unmet need for post-partum family planning. METHODS:Yam Daabo was a multi-intervention, single-blinded, cluster-randomised controlled trial done in six primary health-care centres (clusters) in Kinshasa. Centres were randomly allocated to receive the six-component intervention or standard antenatal and postnatal care in matched pairs (1:1) on the basis of number of monthly births, the ratio of health workers per population in the health zone, and the urban and suburban settings. Only data analysts could be masked to cluster allocation. Health-care facilities were eligible if they provided a continuum of antenatal, delivery, and postnatal care, were well stocked with contraceptives, and were situated close to the main study centre. All pregnant women presenting to the six centres were eligible if they were in their third pregnancy trimester and had no counterindications to deliver in the facility. The main outcome was prevalence of use of modern contraceptives at 12 months after delivery. Analysis was by modified intention-to-treat using generalised linear mixed models or Fisher's exact test for small groups. Prevalence ratios were adjusted for cluster effects and baseline characteristics. This study was registered with the Pan-African Clinical Trials Registry (PACTR201609001784334). FINDINGS:From July 1, 2016, to Feb 2, 2017, eight of 52 clinics assessed for eligibility met the criteria and were randomised. Of 690 women approached, 576 (83%) women were enrolled: 286 in the four intervention clusters and 290 in the four control clusters. Of them, 519 (90%) completed the 12-month study exit interview (252 in the intervention group and 267 in the control group) and were included in the intention-to-treat analysis. At 12 months, 115 (46%) of 252 women in the intervention group and 94 (35%) of 267 in the control group were using modern contraceptives (adjusted prevalence ratio [PR] 1·58, 95% CI 0·74-3·38), with significant differences in the use of contraceptive implants (22% vs 6%; adjusted PR 4·36, 95% CI 1·96-9·70), but without difference in the use of short-acting contraceptives (23% vs 28%; 0·92, 0·29-2·98) and non-modern or inappropriate methods (7% vs 18%; 0·45, 0·13-1·54). There were no serious adverse events or maternal deaths related to the study. INTERPRETATION:The Yam Daabo intervention package did not have a significant effect on the overall use of effective modern contraceptives but significantly increased implant use in women post partum who live in urban settings in Kinshasa up to a year after childbirth. However, interferences from external family planning initiatives in the control group might have diminished differences between the services received. Such an intervention could be potentially relevant in similar contexts in DR Congo and other countries.

Summary Background In rural Burkina Faso, a package of six low-technology, post-partum contraceptive interventions (ie, refresher training for providers, a counselling tool, supportive supervision, daily availability of contraceptive services, client appointment cards, and invitation letters to attend appointments for partners), aimed at strengthening existing primary health-care services and enhancing demand for them, doubled the use of modern contraceptives at 12 months post partum (ie, 55% uptake in intervention recipients vs 29% in routine-care users). This study assessed the effect of a similar package but in urban settings of Kinshasa province, Democratic Republic of the Congo, in an effort to reduce the unmet need for post-partum family planning. Methods Yam Daabo was a multi-intervention, single-blinded, cluster-randomised controlled trial done in six primary health-care centres (clusters) in Kinshasa. Centres were randomly allocated to receive the six-component intervention or standard antenatal and postnatal care in matched pairs (1:1) on the basis of number of monthly births, the ratio of health workers per population in the health zone, and the urban and suburban settings. Only data analysts could be masked to cluster allocation. Health-care facilities were eligible if they provided a continuum of antenatal, delivery, and postnatal care, were well stocked with contraceptives, and were situated close to the main study centre. All pregnant women presenting to the six centres were eligible if they were in their third pregnancy trimester and had no counterindications to deliver in the facility. The main outcome was prevalence of use of modern contraceptives at 12 months after delivery. Analysis was by modified intention-to-treat using generalised linear mixed models or Fisher's exact test for small groups. Prevalence ratios were adjusted for cluster effects and baseline characteristics. This study was registered with the Pan-African Clinical Trials Registry (PACTR201609001784334).

INTRODUCTION Mortality analysis based on a single cause of death is not, in most cases, fully informative. There are several more illuminating procedures using a multiple cause of death approach; these are little known and rarely used in Cuba. The simplest of these methods, while methodologically limited, consists of summing all deaths from a specific cause mentioned on death certificates, regardless of whether the cause is listed as underlying or contributing. OBJECTIVE Using Cuban data, critically assess and implement two of the most recognized approaches to analyzing multiple causes of death. METHODS Multiple causes of death in Cuba were assessed for the years 2005, 2010 and 2015, employing death records from the National Medical Records and Health Statistics Bureau of Cuba's Ministry of Public Health. With the example of diabetes mellitus as underlying cause, we explored connections between underlying and associated (antecedent and contributing) causes on death certificates using two approaches from the international literature: the simple method and the cause-of-death association indicator. RESULTS The study identified main trends in multiple causes of death identified in 2005, 2010 and 2015, overall and by age group and sex. We observed a trend to increasing mean number of causes of death per death certificate between 2005 and 2015. The number of causes reported showed no substantial differences by age group or sex. Diseases of the arteries, arterioles and capillaries were by far the most frequently associated with diabetes mellitus as underlying cause. CONCLUSIONS The multiple causes of death approach affords more nuanced understanding of patterns of disease, comorbidity and death in the Cuban population. The indicators used fulfill different roles: the simple method brings to light the full range of ways in which a given cause contributes to mortality, and the cause-of-death association indicator enables exploration of links between different causes of death, not possible with the simple method.
