How can I use eager loading in this case?

Supposing I have these 6 models such as
User
Profile
Gender
Country
Prefecture
Car
User has one Profile.
Then each Profile has those who are gender_id, country_id, and
prefecture_id User has many Cars
I'm stating asssociation just like this.
models/user.rb
has_one :profile
has_many :cars
scope :confirmed, where("sign_in_count != ?",0)
paginates_per 10
models/profile.rb
belongs_to :user
belongs_to :gender
belongs_to :country
belongs_to :prefecture
models/gender.rb
has_many :user_profile
models/country.rb
has_many :user_profile
models/prefecture.rb
has_many :user_profile
models/car.rb
belongs_to :user
And here's my question!
How can I fix my code in controller, and view?
This my current codes.
CONTROLLER
@users =
User.confirmed.joins(:profile).page(params[:page]).order('profiles.total_point
DESC')
VIEW
<% @users.each do |user| %>
<tr>
Username: <%= user.username %> <br />
Total Point: <%= user.profile.total_point %> <br />
Gender: <%= user.profile.gender.data %> <br />
Country: <%= user.profile.country.data %> <br />
Orefecture: <%= user.profile.prefecture.data %> <br />
The number of the cars that the user owns: <%= user.cars.count %>
<br />
</tr>
<% end %>
