Housing, Health and Health Inequalities
Stephen Battersby MBE PhD FCIEH FRSPH
A tale of two citiesSlide2
Good health starts at home
The home is the main setting for our health throughout our lives – it is fundamental to our health
Housing is a social determinant of health - the “conditions in which people are born, grow, live, work and age, including the health system”
(Marmot)Slide3
Good health starts at home
Social determinants of health are mostly responsible for health inequities - the unfair and avoidable differences in health status
Persisting inequalities across key domains underscore this
Inequalities in early child development & education, employment & working conditions reflect housing & neighbourhood conditions which also affect affect mental health Slide4

Housing and Health
DWELLING
– the physical structure providing shelter, the necessary space, facilities and amenities for the household. Unsatisfactory conditions may lead to one or more direct health effects
(WHO)Slide7
Housing and Health
HOME
- the social cultural and economic structure created by the household, representing a refuge from the outside & enabling the development of a sense of identity; any intrusion of external factors or stressors limits the feeling of safety etc
(WHO)Slide8
Some issues
Housing condition – direct and indirect effects
Cost of housing - increasing debt and reduced ability to have control over one’s life (increasing health inequality)
Security – tenure relevant & frequent moves in PRS not conducive to stable home life – psychological stress (& end of AST most common reason for homelessness (32%) the “defining characteristic”
(NAO)
)
Local environment – no green space, poor air quality, noise, crimeSlide9
Homelessness
65,000 families, 125,00 children currently homeless
More than 300,000 people in Britain sleeping rough or in temporary accommodation
Temporary accommodation often not properly assessed & can be hazardous
Children in temporary accommodation for > one year 3x more likely to demonstrate mental ill health
Moving home many times in early life affects child behaviour
and mental health
(Shelter)Slide10
House to be used for homeless family – (
roof space converted to two bedrooms)
Open riser stair (of varying heights) to first floor from behind rear door in kitchen area of single ground floor room + irregular tread at top step & “ranch” style climbable guardingSlide11
Dampness
Dampness is more likely to occur in houses that are overcrowded and lack appropriate heating, ventilation and insulation
(Institute of Medicine 2004)
,
The
prevalence of indoor damp in low-income communities can be substantially higher than the national
average
(WHO Guidelines for Indoor Air Quality - Dampness and Mould, WHO, 2009)
A damp home is also more likely to be a cold home
Slide12
Cold – Direct impacts
Excess winter deaths
3x higher in coldest quarter than warmest quarter; 40% attributable to cardio-vascular disease &33% attributable to respiratory disease
Children
- >2x more likely to have respiratory problems
Adolescents
>1 in 4 at risk of multiple mental health problems (1 in 20 in warm homes)
Increased COPD, & cardio vascular diseases
Mental ill-health
Arthritis & rheumatism exacerbated
(IHE, UCL)Slide13
Cold – Indirect impacts
Cold homes negatively affects
children’s educational attainment & emotional wellbeing & resilience
family dietary opportunities and choices (to eat or heat dilemma)
dexterity: increases risk of accidents & unintentional injuries
Time off work and loss of earning for occupiers as the result of ill-health (reinforcing poverty & health inequity)
(IHE, UCL)Slide14
(Over)crowding & Lack of space
Adverse effects on children include negative educational performance and behaviour
(Ambrose & Farrell 2009)
Children up to 10 times more likely to contract meningitis
(
Harker
2006)
Overcrowding linked to spread of TB (in 2011 there were 8,963 cases reported
(HPA)
Increase risk of accidents & unintentional injuriesSlide15
Housing Health and Safety Rating System (HHSRS)
Underlying principle - a means of comparing different hazards arising from
deficiencies
and of reflecting the seriousness of these as identified by the ‘surveyor’ or building manager on inspection
It
is NOT a standard – it is a means of assessing dwellings (not actually enforced but underpins any action by local housing authority)Slide16
The HHSRS principles
Any residential premises should provide a safe and healthy environment for any potential occupier (or visitor)
Dwelling unit (letting) should be capable of providing adequate protection from all potential hazards prevailing in local external environment
Some hazards inevitable but risks should be minimised
Slide17
The HHSRS principles
A dwelling that is safe & healthy for the vulnerable age group will be safe and healthy for all
It is the effects of deficiencies that are important not the deficiencies themselves the HHSRS is solely about risks to health and safety Slide18
Potential Housing Hazards
Arranged into four groups -
A - Physiological Requirements
B - Psychological Requirements
C - Protection Against Infection
D - Protection Against AccidentsSlide19

D - Protection Against AccidentsElectric Shocks, Fires, Burns & ScaldsElectrical HazardsFireFlames and Hot Surfaces etcSlide23
Deficiencies & Hazards
One deficiency could give rise to more than one hazard – disrepair to a door and frame & self-closer could give rise to “Entry by Intruders” “Noise” “Excess Cold” (draughts) “Domestic Hygiene Pests & Refuse” depending on the location and nature of disrepair
Many deficiencies could give rise to only one hazard – mould in the bathroom, penetrating damp under to window and through the ceiling all contribute to “Damp & mould” -
single hazard rated once, but greater exposure
greater riskSlide24
Relating People & Hazards
Potential hazards
are assessed
in relation
to the
most vulnerable class of
person (by age)
who might typically occupy or visit the
dwelling, regardless of who actually occupies
e.g.
~ potential hazard from gaps in banisters judged in terms of young
childThe principle is that if a dwelling is safe or healthy for the most vulnerable then it will be safe for allSlide25
“Harm” is
:
The possible health outcome(s) from an occurrence, whether temporary or permanent. That is, the adverse physical or mental effect on the health of a person, such as physical injury, illness, or other health condition or
symptom that would justify medical attentionSlide26
Hazard rating
Identified hazard is rated by a formula that takes account of:
Likelihood or probability of an occurrence (event or exposure that could cause harm) over next 12 months
Percentage spread of possible harm outcomes, from extreme to moderate
The formula produces a hazard score or ratingSlide27
Part 1 Housing Act 2004
Enforcement
by local authorities–
Category 1 Hazards (Bands A –
C or Hazard rating of 1000 or more)
duty
on LHA
to take the most appropriate enforcement action in Part 1 Housing Act 2004
Category 2 Hazards (Bands D –
J or Hazard rating of 999 or less) power on LHA to consider actionSlide28
Points to note
Hazard arises from deficiencies and is rated by reference to the “vulnerable age group” where this has been identified, regardless of actual occupation (an empty property could be rated)
The actual occupation will be taken into account when the LHA considers which if any course of action under Part 1 of Housing Act 2004 e.g. Hazard Awareness, Impro
vement Notice or Prohibition Order etcSlide29
Local authority action
2015-16, 4.5 million households were renting in the private sector (second largest tenure)
28% of private rented homes failed to meet the Decent Homes standard (0.795m with any Cat 1 hazard – 0.229m Excess Cold)
Evidence is many local authorities not using their powers effectively; in 2013/14
Median no. Improvement Notices = 6
Median no. Prohibition Orders = 1
Slide30
Cost of poor housing
The HHSRS Formula allows an assessment of the costs of poor housing to be made as harm outcomes can be “monetised”
– although “exported” or social costs not included
